Description Tamarind kernel powder (TKP), a soluble
agro-residue, was used to examine the production of both
cellulolytic and xylanolytic enzymes in a submerged
culture of Termitomyces clypeatus, an edible mushroom.
Soluble TKP containing xyloglucan as the major polysaccharide
induced all cellulolytic and xylanolytic enzymes,
and enzyme production increased up to 3% (w/v) TKP
with culture filtrate consisting of xylanase and CMCase at
a ratio of 4 : 1 app. Strong catabolic repression of enzyme
production was also observed with the soluble substrate,
although fed-batch addition of soluble substrate at late
growth phase modified the enzyme kinetics by improving
the yield by 30%. The results indicate that inducers were
possibly released from TKP by cellulose and xylan fractions
of the lignocellulosic polymer. Therefore, the present
study reports the successful economic utilization of TKP,
an abundantly available soluble agro-residue, for the production
of both cellulolytic and xylanolytic enzymes in a
single fermentation method.
