Abstract
: A formulated fish feed was fermented employing two strains of
Saccharomyces cerevisiae in solid state fermentation (SSF) at their
corresponding optimized growth conditions. The strain Sn-1Y enhanced
protein content of fermented feed up to 31.68% after 72 hours. While Sn5Y showed increase of protein content up to 32.90% after 48 hours. Total carbohydrate content of the feed showed a declining trend up to 54.54% for Sn-1Y and 55.39% in case of Sn-5Y after 168 hours of fermentation. Maximum reduction (42.50 and 16.25%) of free amino acids occurred for Sn-1Y and Sn-5Y after 72 and 48 hours of incubation, respectively. The present study showed that the fermentation of the fish feed by S. cerevisiae may improve its quality. Application of such feeds may economize the development of aquaculture in this country
