- ItemProduction of Wine from the Fermentation of Cherry by Saccharomyces cerevisiae(2025-12-12) Mubarak Muhammed Abdulrazaq a*, Bajepade Toheeb Taiye a*, Uthman Lateefat Saheed a, Ummulkhair Aliyu a, Durosinmi Halimah Adekunbi a, and Kareem Hussaini KehindeThis study investigated the fermentation potential and physicochemical characteristics of cherry wine produced using Saccharomyces cerevisiae isolated from naturally fermented palmwine, with comparisons drawn against standard values for fruit-based wines. The study also aimed to evaluate the yeast’s sugar fermentation capability and the nutritional and antioxidant properties of the resulting cherry wine. Study Design: A laboratory-based experimental design was adopted, incorporating statistical analyses to monitor microbial load, fermentation progress, and proximate composition changes overtime. Place and Duration of Study: Microbiology Laboratory, Kwara State University, Malete, Kwara State, Nigeria from March 2025 to April 2025. Methodology: Fresh cherry fruits were procured from the Malete market in Kwara State, Nigeria, while yeast for fermentation was isolated from freshly tapped palm wine. Yeast isolation was conducted using Potato Dextrose Agar (PDA) prepared and sterilized under standard conditions, with isolates characterized morphologically, microscopically, and biochemically through sugar fermentation tests. Cherry fruits were washed, peeled, deseeded, blended, and treated with sodium metabisulfite before fermentation. A yeast starter culture of Saccharomyces cerevisiae was reactivated and inoculated into the prepared cherry must, supplemented with nutrients such as sugar, potassium phosphate, ammonium sulfate, citric acid, and magnesium sulfate. Fermentation was monitored daily for physicochemical changes, including pH, specific gravity, total soluble solids (°Brix), titratable acidity, and alcohol content. Proximate analyses of the final product measured moisture, ash, crude fiber, crude protein, and fat content. Microbiological safety was assessed by bacterial enumeration and coliform detection. Antioxidant properties of the cherry wine were evaluated DPPH free radical scavenging assay, hydrogen peroxide scavenging assay, ferric reducing antioxidant power (FRAP), and nitric oxide scavenging assay. Sensory evaluation was conducted comparing the fermented cherry wine with a commercial wine. Results: The isolated Saccharomyces cerevisiae from palm wine demonstrated effective fermentation of cherry must, characterized by a progressive decline in specific gravity (from 1.085 to 1.070) and pH (from 3.5 to 3.1), alongside an increase in alcohol content from 0.31% to 6.32% v/v over 9 days. Total soluble solids decreased while titratable acidity showed a consistent decline. Microbiological analysis confirmed the absence of Staphylococcus spp., E. coli, and coliforms, indicating the microbial safety of the wine. Proximate analysis showed that cherry wine had higher moisture and carbohydrate content but lower ash, protein, fat, and fiber compared to fresh cherry fruit. Antioxidant assays revealed moderate activity (50–58%) across DPPH, nitric oxide, FRAP, and hydrogen peroxide scavenging tests. Sensory evaluation showed that while the commercial wine was rated higher overall, the cherry wine received favorable scores in taste and aroma. Conclusion: The study demonstrates that Saccharomyces cerevisiae isolated from palm wine effectively ferments cherry must into a safe, nutritious, and sensorially acceptable wine. The findings support the potential for local production of cherry wine with desirable quality attributes using native yeast isolates.

- ItemAssessment of the Use of Eyewitness Reports by Channels Television(Media and Communication Currents, 2024) Shaibu Agnes Joe; Udende PatrickEthical concerns surrounding eyewitness materials from citizens often necessitate structured guidelines for integrating them into television productions. This study assessed Channels Television’s use of eyewitness reports in the Eyewitness Report programme. The objectives the study sought to achieve were to identify reasons for Channels Television‘s Eyewitness Report; to examine the mode of sourcing and utilising eyewitness reports; to examine procedures for making eyewitness reports conform to the station’s policies/ethical guidelines and to examine the mode of authenticating eyewitness materials from audience members. This was premised on the gatekeeping theory. The study adopted a qualitative research design, with the key informant interview method to garner insights from News and Current Affairs department personnel involved with the Eyewitness Report programme. A purposive sampling technique was used to select four key informants based on access, availability and knowledge of the subject. Data from the interviews were analysed thematically. The study found reasons behind the use of eyewitness reports to include that of addressing gaps in news coverage. In sourcing and utilising eyewitness reports, the programme actively engaged with the public through various platforms, emphasising credibility and quality checks Furthermore, the study uncovered that meticulous verification processes, follow-up and collaborative decision-making were employed in utilising citizen eyewitness reports. The study concluded that adherence to journalistic guidelines in the context of the Eyewitness Report demonstrates a commendable approach to incorporating citizen voices into the news agenda. The study therefore recommended that Channels Television provide clear guidelines for citizen contributors and communicate the same to the public in addition to its message soliciting eyewitness contributions.
- ItemThematic Analysis of Al-Jazeera Documentary, unrest forces farmers off their land, on Farmer-Herder Conflict in Nigeria(Metacommunication: Journal of Communication Studies, 2025) Subair Bashirat DamilolaThe conflict between farmers and herders in Nigeria has, over time, impacted adversely on ethnic tolerance, agriculture, source of livelihood, sheltering and lives of many. In the process, the media have been noted to have exerted a great deal of influence on the perception of people on the array of issues reported by the media. It is against this backdrop that this study sought to examine the portrayal of Unrest forces farmers off their land, a documentary produced by Al Jazeera, on specific themes portrayed in the documentary, government responsibility towards the conflict, the portrayal of language in the documentary and to determine the consequences of the conflict portrayed in the documentary. A qualitative content analysis was performed on the documentary having determined the content categories. The study found that the documentary moderately portrayed peace journalism, government’s inability to do enough in curbing the conflict between farmers and herders, which affected the effectiveness and outcomes of the peace journalism. This is akin to the notation that the media engagement of the conflicting parties, in order to allow them to state their needs, wants and expectations from the other conflicting party and the government, will go a long way in the settlement of the conflict. Therefore, the media are one of the determinants of the escalation or de-escalation of conflict issues. The media should therefore practice continuity in the ways by which they handle conflict issues and to contribute immensely to conflict resolution, peace building of conflict-related issues, to prevent reprisal attacks. More so, the conflict between farmers and herders would subside if government gives adequate attention and act duly in resolving the conflict.
