dc.description.abstractIn this study, superfluous jute plants and jute stick were converted into upgraded animal feed by solid state fermentation (SSF) using a cellulolytic fungus, Pleurotus sajor-caju. Prior to fermentation, substrates were subjected to several pretreatments such as soaking with water overnight and alkali or lime pretreatment. SSF was carried out with 20 g of substrate in 100 ml conical flask and was incubated at 30C for 8 weeks. In all treatments, the highest amount of reducing sugar, soluble protein as well as the cellulolytic activities of three enzymes viz. cellobiase, carboxymethyl cellulase and avicelase were obtained at 6th week of fermentation. Compared to raw, unsoaked substrates, soaking treatment alone could produce 10% more soluble protein in both substrates whereas reducing sugar increment was 5% and 6% in jute sticks and jute plants, respectively. From all treatments, combination of soaking and lime treatment in green jute plants yielded higher value than jute sticks in terms of reducing sugar, soluble protein and enzymatic activity. The radiation doses at 20, 30 and 40 kGy appeared to have no effect on sugar and protein accretion. During eight weeks of fermentation, relatively higher cellobiase activity was found compared to that of carboxymethyl cellulase and avicelase. The present investigation indicates that fungal conversion with pretreatment can turn these lignocellulosic agro-wastes to a nutritionally enriched animal feed by increasing the crude protein and reducing sugar content. However, further research is necessary to develop strategies for industrial scale production to overcome the crisis of nutritionally improved animal feed.
