Biopreservation of Tomatoes Using Bacteriocin Produced by L. Plantarum SJC 103 and L. Apis Hbam1
(0002)
Several species of Lactobacillus have been known to produce an antimicrobial peptide known as bacteriocin, which are generally regarded as safe thus making them suitable as food additives a*nd thereby fulfilling consumers demand for chemical free food. The aim of the study was to produce bacteriocin from Lactobacillus plantarum SJC103 and L. apis HBAM1 and use the bacteriocin produced as a biopresevative of tomatoes. Production of bacteriocin from both Lactobacillus species was performed using broth cultures of the selected isolate were centrifuged at 4000 rev/min for 1 hr and the supernatant which contained the was then decanted. The bacteriocin produced was purified using ammonium sulphate precipitation. Microbial analysis was conducted on untreated tomatoes (control), tomatoes treated with bacteriocin, and Staphylococcus aureus infected tomatoes treated with bacteriocin and all were stored under the same conditions. The biopreservative potential of bacteriocin from both isolates produced a reduction in colony for the treated tomatoes with 1.10 x 107 cfu/g and 2.15 x 107 cfu/g for L. plantarum and L. apis respectively which were significantly reduced when compared with the S. aureus infected tomatoes with 9.25 x 107 cfu/g on day 10 of preservation. It was concluded that bacteriocin from Lactobacilli can be harnessed as a natural antibacterial in the preservation of tomatoes.
Toxicological implications of crude alkaloidal fraction from Cnestis ferruginea D.C root on liver function indices of male Wistar rats
(2009) TG Atere and AT Ajao
The crude alkaloidal fraction of Cnestis ferruginea D.C root was evaluated for its effect on the liver function indices of Wistar rats. Prior to the evaluation, the LD50 of oral route was established which is 27 mg/kg body weight. For the sub-acute toxicity studies, albino rats were grouped into four (A-D). Groups A, B and C were orally administered with 3, 6 and 9 mg/kg body weight of the alkaloidal fraction on daily basis for 14 days while group D (the control) was treated like the test groups except that they received distilled water. The liver function indices were monitored progressively 24 h after 1, 7 and 14 daily doses of the alkaloidal fraction. The reduction (P<0.05) in the activities of liver alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in all the alkaloidal treated groups were accompanied by corresponding increase in the serum enzymes. Similar administration of the alkaloidal fractions increased the serum concentrations of albumin, conjugated and total bilirubin. The total protein in the serum and liver-body weight ratio decreased significantly. The histopathological examination revealed mild to severe disruption of the normal structural architecture of the liver characterized by the presence of red blood cells in the hepatocytes. The results suggest that alkaloidal fraction of Cnestis ferruginea D.C root has adverse effect on hepatic functions.
Studies on the biodegradation and utilization of selected tuber wastes by Penicillium expansum.
(2009) AT Ajao, HJ Abdullahi, TG Atere and OM Kolawole
Some fungi were found to be associated with the degradation of selected tuber starch wastes (Yam Peels, Cassava Peels, Sweet Potato Peels and Cocoyam Peels) of which eight showed amylase production on the Potato Dextrose Agar (PDA) supplemented with soluble starch. Penicillium expansum was selected among the isolates and used to ferment the extracts prepared from each of the tuber starch wastes for 144hours.Yam peel was found to be highly susceptible to the degradation while cocoyam peels was most resistant to the degradation. Fermentation of each of the waste extracts showed the ability of the organism to increase the protein contents, amylase activities of the waste extract with the increase in biomass. However, concentration of sugar and starch reduced considerably.

(2009) AT Ajao and TG Atere
This study reports the status of hygiene standard and bacteriological quality of food provided at the Kwara state Polytechnic, food canteens. Six canteens were randomly selected for the study.Ten assay visits were carried out and total bacterial counts from various environment surfaces, palms of the food handlers and various denominations of money from food sellers were determined using Agar Syringe Method containing nutrient agar for the evaluation of hygiene quality index.Food quality was also determined by testing for total viable counts, coliform,Salmonella Pseudomonas and Staphylococcus counts. The sensitivity of the bacterial isolates to some antibiotics was also evaluated. Result of the study indicated that clean plates, walls tables and serving counters have high hygiene quality indices of 75%, 91%, 62% and 65% respectively. While floor, hand towels, apron, money and hand swabs have low hygiene quality indices of 53%, 36%, 56%,46% and 40% respectively. Pudding and stew samples were of low microbial and compare to water and vegetable. Coliforms (10.8%), Salmonella sp(11.0%). Enterobacter sp(10.3%) and Bacillus sp (12.5%) were mostly occurred during the sampling period. The isolates were sensitive to some antibiotics while some were resistant. This study suggest that there is need to improve on hygiene practices in Kwara state polytechnic canteens in order to prevent or reduce as the case may be the incidence of food borne disease.

(2011) Adedayo, M .R. , Olayemi, F. F. and Bamishaiye, E. I.
The study was carried out to determine the proximate and mineral composition of a local non alcoholic drink made from the fruit pulp of baobab (Adansonia digitata). The fruit pulp was obtained by manually removing the pulp from the seed. Hundred grammes (100g) of the fruit pulp was dissolved in one litre of sterile distill water for 10 min to make the local drink. The baobab drink thus produced was analyzed for their proximate and mineral composition to ascertain their quality as a fruit drink. It was observed that the drink has various minerals with the highest percentage in potassium (130ppm), followed by magnesium (29.8ppm), copper (17ppm), manganese (13ppm) and calcium (12.2ppm) while protein was found to be 2.2mgg-1, ash 4.4%, p H 3.1. The Vitamin C content was 26mgg-1 and the sensory evaluation also showed that the fruit drink was well accepted by the consumer.
Antimicrobial property of palm wine
(2011) Adedayo Majekodunmi Rachael and Ajiboye Adeyinka Elizabeth
Palm wine was assessed for its antimicrobial property. The antimicrobial property was assayed on five bacteria: Escherichia coli, Staphylococcus aureus, Proteus mirabilis, Pseudomonas aureginosa and a Bacillus sp with one fungus Candida albicans. The minimum inhibitory concentration and the minimum bactericidal concentration of palm wine on these organisms were determined using agar well diffusion method. The antimicrobial activity on these organisms was then compared with the action of methylated spirit, a known commercial disinfectant. Palm wine was found to be more active against the gram negative organisms (Escherichia coli, Pseudomonas aureginosa and Proteus mirabilis) than the gram positive organisms (Bacillus sp and Staphylococcus aureus). The action was bactericidal on the gram negative organisms while it was bacteristatic on the gram positive. It was found out that palm wine had no inhibitory or cidal action on Candida albicans which is one of its resident organism. The antimicrobial action was also found to compare favorably with methylated spirit a known commercial disinfectant.

(2011) A. E. Ajiboye1 *, O. M. Kolawole2 , T. O. Oladosu2 , M. R. Adedayo1 and J. K. Akintunde1
Dried meat (Tinko) samples obtained from the Oja-Oba market in Ilorin metropolis during the rainy season were investigated for their microbial flora and the sensitivity of the bacterial isolates to different chemotherapeutic antibiotics under two different storage conditions (Cupboard and Refrigerator) for a period of five weeks revealed that the moisture content of dried meat samples stored in the cupboard increased from 35 to 65%, while those in the refrigerator had an initial increase from 50 to 55% for the first two weeks of storage and became constant through the period of storage. Bacteria and Fungi isolated include Staphylococcus aureus, Micrococcus luteus, Neisseria sp., Acinetobacter sp., Aspergillus niger, Aspergillus flavus, Penicillium sp. and Rhizopus sp. Bacterial isolates showed resistance to selected antibiotics (erythromycin, tetracycline, chloramphenicol, gentamycin, streptomycin, ofloxacin, nitrofurantoin, ciprofloxacin, azithromycin and clindamycin) except for Neisseria sp. which was sensitive to the antibiotics. The total bacterial count increased in the dried meat stored in the cupboard (2.5 × 107 to 3.3 × 107 cfu/ml) while it decreased in the meat samples stored in the refrigerator (2.0 × 107 to 1.4 × 107 cfu/ml).
Single Cell Proteins: As Nutritional Enhancer
(2011) Adedayo, M.R. Ajiboye, E.A., Akintunde, J.K., Odaibo, A.
To meet the protein need of our growing population, it is important to include non-conventional protein sources in our diet. Important non – conventional sources are oil seed proteins, leaf protein concentrate, (LPC) fish protein concentrate (FPC) and single cell proteins (SCP) or biomass protein (BMP). Single cell protein recently attracted attention and holds a major potential for increasing protein supply. Proteins not only provide a nutritional component in a food system but also perform a number of other functions).The protein obtained from microbial source is designed as “Single Cell Protein” (SCP). Bacteria, Moulds, Yeasts, Green and Bluegreen algae are widely used as source of single cell protein. However, blue-green algae, where cell wall lacks cellulose, are easily digestible and are the most frequently used organism. Microbial protein or SCP has various benefits over animal and plant proteins in that its requirement for growth are neither seasonal or climate dependent; it can be produced all round the year .Does not require a large expanse of land as in plant or animal protein production. It has high protein content with wide amino acid spectrum, low fat content, higher proteincarbohydrate ratio than forages, can be grown on waste and it is environmental friendly as it helps in recycling waste. Various forms of organic waste such as cellulose hemicelluloses, hydrocarbon and different types of agricultural waste are used in the production of SCP. Besides nutritional value, a protein should have desirable functional properties also for its incorporation in food. Functional properties of proteins vary with the source, composition, method of preparation/extraction, prevailing environment etc. SCP has been found to meet all the requirements for its inclusion as diet supplement for both human and livestock especially in the developing countries of Africa and the world at large. This paper is therefore aimed at reviewing the in production, processing and consumption of SCP for food and feed.

(2011) Olayemi Folorunsho Foline, Adedayo Majekodunmi Rachael, Bamishaiye Eunice Iyabo and Awagu Emenike Fidelis
The effect of drying on proximate compositions of catfish (Clarias gariepinus) using Nigerian Stored Products Research Institute (NSPRI) developed kiln was determined. The purchased quantities of catfish were shared into two parts; one part was used to determine the proximate compositions of the raw fish and the other part was dried using smoking kiln at a temperature range of 60 to 70°C for 15 h. The proximate compositions of the fresh and dried samples were determined. Also, sensory evaluation was also determined using 9 point hedonic scale. Protein, carbohydrate, moisture content, fat, ash and nitrogen free extract (NFE) for fresh and dried fish were 16.24, 0.92, 78.70, 0.50, 1.33, 2.31% and 68.4, 1.80, 7.30, 12.50, 6.40, 3.60% respectively. The general acceptance as shown by sensory evaluation was equally high. It was therefore concluded that drying does have a positive effect on fish since there was an increase in embedded nutritional parameters.

(European Journal of Applied Sciences, 2012) Atuanya, E. I., Aborisade, W. T. and Nwogu, N. A.
The impact of plastic enriched composting on soil structure, fertility and growth of maize (Zea mays L.) was examined in this study. A completely randomized blocked design (RCBD) consisting of five treatments viz., A (Control, untreated soil), B (0.83% treatment level), C (1.67% treatment level), D (2.50% treatment level) and E (3.33% treatment level) with three replicates each was used. The result of the physico-chemical parameters of the soil revealed that the addition of plastic granules to the soil resulted to increase in the total organic carbon content and bulk density of the soil. However, other nutrient elements of the soil were not affected. Among the treatments, there was no significant difference (P<0.05) on the germination of Zea mays seedlings. The result of impact of plastic on the growth showed that the higher the plastic granules the more its negative impact on Zea mays growth. A (36.51 ± 1.30 cm) had the highest growth while the least growth was observed in D (28.50 ± 0.74 cm) and E (28. 78 ± 1.64 cm) treatments after eight weeks of planting.

(2013) ADEDAYO MR, OLAYEMI FF, BAMISHAIYE EI, MOHAMMAD HR AND AJIBOYE AE
The research was carried out to produce a locally fermented dairy product “nono” from powdered milk. Microbiological and nutritional qualities of the product were assessed. The mean total plate count of nono was 1.0 x103 cfu/ml, the mean coliform count was 0.0 x103 cfu/ml while the mean fungal count was 10.0x103cfu/ml for the nono produced. The moisture content of the powdered milk nono was 80.0g/100g, total titratable acid was 1.8 and pH was 5.7. The values obtained for crude protein, total carbohydrate, and crude fat were 1.8g/100g, 17.7g/100g, and 0.5g/100g respectively. The absence of coliform organisms in the powdered milk nono and the physicochemical profile shows it is of good nutritional value and essentially a good source of defatted milk for children, adults and aged.

(2014) Ajiboye AE1*, Ajuwon IB1 and Adedayo MR1
An investigation was conducted on the microflora associated with the pulp of fresh and rotten fruits of Annona muricata. Microflora was more in the rotten fruits than in the fresh fruits. Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Proteus sp., Klebsiella sp., Rhizopus sp., Fusarium sp., Candida sp., Mucor sp. and Aspergillus niger were the microorganisms isolated from the rotten fruits while S. aureus, Micrococcus sp., P. aeruginosa, Aspergillus niger, Candida sp. and Penicillium sp. were isolated from fresh fruit. Rhizopus sp was the most dominant mycoflora in the rotten fruit having a percentage mean occurrence of 37% while P. aeruginosa, S. aureus and Proteus sp., were the most dominant bacteria in the rotten fruit with a percentage occurrence of 23.1%. Proximate composition and physicochemical analysis were carried out on the pulp of the rotten and fresh fruit. The results showed that the pulp of the fresh and rotten fruit contained an approximate mean value of 72.9 and 80.7% moisture, 11.8 and 10.5% ash, 0.84 and 0.76% titratable acidity, 4.01 and 2.89% crude fiber, 1.55 and 0.24% lipid, 1.43 and 0.42% protein, 8.47 and 5.25% carbohydrate and pH of 4.57 and 6.63 respectively. Different microorganisms, specifically bacteria and fungi occur within the rotten and apparently fresh fruits of A. muricata and these microbes can have health implication on humans and affect the value of the fruits in the food industry.

(2015) Adedayo, Majekodunmi Racheal1 and Sani, Alhassan
The effects of fungal fermentation on the amino acid profile and mineral composition of the pulverized seed of baobab (Adansonia digitata) were investigated in this study. Penicillium citrinum, Penicillium chrysogenum, Rhizopus stolonifer, Mucor hiemalis, Mucor racemosus, Alternaria tenuis, Scopuloriopsis brevicaulis, Aspergillus niger and Aspergillus flavus were isolated from naturally decomposed seed kernel and used singly to ferment the seed kernel flour of Baobab for five days (120 hours). The fermented samples were oven dried at 600 C and analyzed for their amino acid and mineral content standard methods. The amino acid content was obtained by using the Technicon sequential multi-sample amino acid analyzer (TSM) while the mineral content was done with the Atomic Absorption Spectrometry (AAS). The amino acid values of the fermented samples were higher (1.2-8.7mg/100g protein) compared to the unfermented sample except for phenylalanine (5.2-4.7mg/100gprotein). Essential amino acids particularly methionine, histidine, isoleucine, arginine, leucine, valine threonine and lysine content of fermented samples increased significantly. The chemical score of histidine (168-255%), leucine (127-129%) and threonine (107-109%) in M. hiemalis fermented sample, valine (117-133%) and arginine (102-106%) in P. chrysogenum were found to meet up with the daily requirement reference of the FAO/WHO/UNU standard for livestock, children and adults. The result of the analysis of the mineral composition of the fermented samples; Calcium (257- 559mg/kg) Potassium (258-263mg/kg), Magnesium (60-243mg/kg) and iron (130-188mg/kg) showed that they had significantly increased compared to the unfermented. It is concluded that fermented baobab seed can be a potential replacement of protein in livestock feed formulation.

(2015) Ajiboye, Adeyinka E.1 * and Sani, Alhassan2
The aim of this research was to produce citric acid from the fruit pulp of Dialium guineense using naturally occurring fungi in a solid state fermentation. The fruit pulp was de-capped from the seed and dried at 60 oC in an oven. Natural fermentation was carried out for seven days at 28 0C ± 2. The fungi were isolated and identified as Aspergillus niger, Aspergillus flavus, Penicillium chrysogenum, Penicillium citrinum, Mucor hiemalis, Mucor racemosus, Rhizopus stolonifer, Alternaria tenuis Syncephalastrum racemosus, Saccharomyces cerevisiae and Schizosaccharomyces pombe. They were screened for citric acid production using standard methods. Yellow coloration confirmed citric acid production after five days of incubation. Organisms that were strongly positive for citric acid production include Aspergillus niger, Aspergillus flavus, Penicillium chrysogenum, Penicillium citrinum, Mucor racemosus, and Alternaria tenuris. They were used to ferment the fruit pulp of D. guineense in a solid state fermentation by inoculating 2ml spore suspension of 2x10 5 spores/ml of each of the isolates on separate Erlenmeyer flasks of 250ml for seven days at 28 ± 2 oC. Quantitative production of citric acid was determined using standard methods. Aspergillus niger had the highest citric acid production of 14.07mg/g while Aspergillus flavus had the lowest citric acid production of 6.34mg/g. The result of this investigation reveals that some of the naturally occurring fungal isolates from the natural fermentation of the fruit pulp of D. guineense are capable of utilizing the substrate for the production of citric acid and could be employed for the production of citric acid on large scale.

(2016) MAJEKODUNMI RACHEAL ADEDAYO, SHOLA KOLA BABATUNDE, ADEYINKA ELIZABETH AJIBOYE , LATEEF MODUPE HABEEB
Objective: To determine the antimycotic potency of the aqueous and ethanolic extract of the fruit pulp of Tamarindus indica on human pathogenic Candida al-bicans. Methods: The disk diffusion method was employed to check for the antimycotic potency of extracts while qualitative and quantitative analysis of some phyto-chemical constituents was carried out following stand-ard methods. Results: The fruit pulp extracts were effective against the organism at 475 and 485 mg/ml in the aqueous and ethanolic extract respectively. The same concentration served as the Minimum Inhibitory and Minimum Fun-gicidal Concentration (MIC and MCC) in both extracts. The extracts were also subjected to qualitative and quantitative phytochemical analysis. Alkaloids, tan-nins and reducing sugars were found in the ethanol ex-tract while in the aqueous extract glycosides, saponins and reducing sugars were discovered to be present. Conclusions: The study indicated that aqueous and eth-anolic extracts of the fruit pulp of T. indica can be a potential source of antimycotic agent to combat the challenge of the emergence of drug-resistance in Can-dida albicans and the need to produce more effective antimicrobial agents.
