RADIATION AND NRSP EFFECT ON PROTEIN, FILTRATION EFFICIENCY AND CRUDEFIBER DEGRADATION AFTER SUGAR-CANE BAGASSE FERMENTATION BY MUSHROOM FUNGI

The upgrading of sugar cane bagasse with natural rubber waste by irrad iation and three mushroom fungi was studied in order to produce econom ical animal feed and mushrooms. The protein concentrations changed a l ittle at 0, 1% of NRSP but greatly increased at 5% NRSP concentration with irradiation and nonirradiation in liquid fermentation. The filtra tion rate decreased at 5% NRSP concentration after liquid fermentation but it increased by 2.7, 10.2, 11.1 times with irradiation for P. saj or-caju, C. phlytidosprorus and P. flavellatus. The amounts of crude f iber were decreased due to the irradiation and the different concentra tion of NRSP after 42 days of solid fermentation by P. sajor-caju. (C) 1998 Elsevier Science Ltd.
