Isolation and characterization of yeast from palmwine;- Ezeibekwe, Francis N

ABSTRACT

 Palm wine is a cheap source of yeast that can augment for the more expensive commercial yeast. Utilizing palm wine yeasts for industrial processes requires a comprehensive knowledge of their technological properties. In this work, yeasts were isolated from Palm wine and subsequently characterized and identified. Seven randomly selected palm wines were cultured by streak plate and spread plate method. Obtained results showed three primary yeast species with varying prevalence in palm wine samples. Three yeasts were isolated Saccharomycescerevisiae, Saccharomyces globobus and Saccharomyces carlsbengensis. Saccharomyces cerevisiae was found in all samples while Saccharomyces globobus and Saccharomyces carlsbengensis had 71.43% occurrence (5/7) and 57.14 %(4/7). Yeast isolated from palm wine can be used in the production ofwine.
