Description Cellulase [see 1,4-(1,3;1,4)-~-D-glucan 4-glucanohydrolase, EC 3.2.1.4], (J-D-glucosidase (~-D-glucoside
glucanohydrolase, EC 3.2.1.21) and D-xylanase (],4-~-D-xylan xylanohydrolase, EC 3.2.1.8)
production by Aspergillus ustus, Sporotrichum pulverulentum, Trichoderma sp. (a), Trichoderma
sp. (b) and Botrytis sp. in solid state fermentation on different compounded media containing wheat
bran {WB), rice straw (RS) and minerals was studied. Toyama's mineral solution mixed with RS was
found to be a better substrate for cellulase and D-xylanase while with WB it induced higher ~-Oglucosidase
production. A ratio of substrate to mineral solution (w/v) of 1:4 or 1:5 supported high
D-xylanase and cellulase production whereas a ratio of 1:2 gave the highest [J-D-glucosidase activity.
Among the fungal isolates, Aspergillus ustus gave the highest [J-D-glucosidase activity of 60 U g -1 WB
and the highest D-xylanase activity of 740 U g-1 was obtained with RS. A mixture of seven parts of
RS and three of WB, mixed with 40 parts of Toyama's mineral solution yieMed 6 U filter paper
activity, 40 U ~-D-glucosidase, 12 U carboxymethylcellulase and 650 U D-xylanase g-1 substrate.
