Potentials of Saccharomyces cerevisiae Y10 as a Starter Culture for Wine Production from Date Palm (Phoenix dactylifera) Fruits

Abstract

A considerable quantity of agricultural produce in Nigeria gets spoilt due to lack of storage facilities and poor storage conditions. An example of such agricultural produce is date palm which is readily available in the northern parts of Nigeria. This study aimed at evaluating the potential of Saccharomyces cerevisiae Y10 isolated from decomposed sugarcane bagasse to produce wine using date palm fruits. The yeast was isolated using yeast extract peptone dextrose agar and was identified by molecular methods. Fermentation of date palm fruit juice was carried out anaerobically for 20 days during which physicochemical parameters and proximate composition were determined using standard methods. The yeast was identified as Saccharomyces cerevisiae Y10 with accession number MG321589. Analysis of physicochemical properties showed that pH dropped from 5.4 to 3.6, titratable acidity increased from 0.25 to 0.71% and specific gravity decreased from 1.1 to 1.01. Proximate composition of produced wine gave low total reducing sugar and low protein of 0.11 and 0.44% respectively and the final alcohol content was 10.4% at the 20th day of fermentation. This study has shown that Saccharomyces cerevisiae Y10 which was isolated from decaying sugarcane bagasse sample has the potential to be used as starter culture for fermentation of date palm for wine production.

Assessing Potential of Biogas: Harnessing Sustainable Energy from Biomass for Renewable Solutions (Review)

“…Moreover, biogas integration with circular economy models offers synergistic opportunities for resource recovery and value creation. Circular economy principles advocate for the redesign of systems to minimize waste generation and maximize resource utilization through reuse, recycling, and regeneration [6] ( Adeleke et al, 2023). Biogas projects can be integrated into circular economy frameworks by co-digesting diverse organic waste streams, implementing nutrient recovery technologies, and exploring symbiotic relationships with other industries [7] (Agori et al, 2023).…”

“…Through anaerobic processing, natural waste like agrarian buildups, creature compost, and food scraps can be changed over into biogas, lessening methane discharges from deterioration and landfills. As indicated by [6] Adeleke et al, (2023), biogas creation from natural waste can essentially moderate ozone harming substance discharges, offering a lowcarbon option in contrast to conventional energy sources. Moreover, biogas digestate, a result of the assimilation cycle, fills in as a supplement rich manure, advancing soil wellbeing and decreasing the requirement for engineered composts [7] (Agori et al, 2023).…”
