ABSTRACT
The basic objective is to study the effect of Brevibacillus borstelensis R1 and its partially purified α-
amylase along with Saccharomyces cerevisiae in ethyl alcohol dual fermentation. The production of ethyl
alcohol was estimated and analyzed for 30 days at regular intervals. Yeast extract, peptone and starch
medium (YPS) was inoculated with Saccharomyces cerevisiae as control and with Saccharomyces
cerevisiae and Brevibacillus borstelensis R1 as test. In our studies of dual fermentation, 5% co-strains of
Saccharomyce cerevisiae and Brevibacillus borstelensis R1 showed maximum (3.37±0.23U/ml) alcohol
production on the 21st day.
Keywords: Brevibacillus borostelensis R1, α-amylase, Saccharomyces cerevisiae, Dual fermentation, alcohol.
