Fermented Cassava Rubber (Moniho Fermentasi Singkong Karet (Monihot carthagenensis MÜII) Menjadi EtanolDengan Pemanfaatan Albumin Dari Ikan Gabus (Channa striata) Sebagai Sumber Nitrogen Bagi Mikroba
Abstract
Has been cassava rubber fermentation (M. carthagenensisMÜll) as a raw material for making ethanol with the utilization of fishcork albumin (Channastriata) as nitrogen Saccharomyces cerrevisiae with enzymatic hydrolysis result through 2 stages ieliquification using α-amylase and saccharification stage using gluco -amilase. The best reducing sugar content was obtained at 0.1307%. Based on this research, maximum ethanol content was obtained with 0.5% concentration of nutrient at fermentation time for 232 hours, obtained by result of 12,688% at 5.6 mL distillate volume using gas chromatography method.
