The
feasibility of using apple pomace for cellulase production
by Trichoderma sp. under solid state fermentation was
evaluated in this study. Our results indicated that initial
moisture level of the medium, incubation temperature and
inoculum size influenced the cellulase production greatly.
The optimum initial moisture level, incubation temperature
and inoculum size were 70%, 32 and 2×108
spores/flask, respectively. The supplement of lactose and
corn-steep solid to the apple pomace favored the enzyme
formation markedly.
