Saccharomyces sp. Sugarcane juice
 
Description 401-405
Various indigenous strains of Saccharomyces sp. (SCP-1, SCP-3, SCP-4, SCP-5, SCP-7) isolated from datepalm (Phoenix
dactylifera) sap were evaluated for alcohol dehydrogenase (ADH) enzyme activity, ethanol production and alcohol tolerance
limits and compared with standard culture of S. cerevisiae (S.C.Std). Alcoholic contents in juice samples fermented with
different yeast strains varied considerably (8.9-12.5%, v/v) as determined by GLC. Yeast cultures showed varied in vitro ethanol
tolerance (3-12%). Isolate SCP-1 was found superior showing 12.5% ethanol production, high ADH enzyme activity (4.38
units/ml) and higher alcohol tolerance maintaining cell viability at 12% ethanol in YPD medium up to 48 h
