BIOCONVERSION OF RICE STRAW INTO PROTEIN RICH FEED

Abstract

                                Three cellulolytic fungi were inoculated on alkali hydrolysed rice straw and untreated rice straw, Asperquillus sp. (AS.3) exhibited maximum straw conversion (80.0%) followed by Fusarium sp. (Fs.4) and Trichodermu sp. (T.3) Fungal biomass yield ranged from 82 to 1.06 g/50 ml depending upon the fungi. Crude protein content of rice straw after fermentation varied from 15.6 to 25.0% irrespective of the type of rice straw and the fungi. Soluble protein of the fermented rice straw was maximum (42.5 mg/100 ml) in Aspergillus sp. (As.3) insulated substrate. The results showed the possibility of obtaining protein enriched rice straw employing efficient cellulosic fungi.
