Soy bean seed-coat, potential renewable raw-material for alcohol production

Kailash Chandra Srivastava


The seed coat was shaken for different periods of time, from 12 hr to 96 hr in sterile distilled water pre-adjusted to pH 8. The contents of the flask filtered and pH adjusted to 4.6. Next the solution was heated for 20 min at 90° C in a waterbath, filtered and media prepared from the filtrate. These media were inoculated with 10% volume of a strain of Saccharomyces Cerevisiae. The suspension shaken on a rotary shaker at 250 rpm and 30°C ± 1°C for 48 hr after which the culture filtrate was distilled and the amount of alcohol measured according to the alcoholometric tables of the U.S. Pharmacopia. Thus up to 1.3% of alcohol could be obtained.
