CONCLUSIONS
The productions of bioethanol from
agricultural cellulosic materials are important
for energy generation as biofuel. Penicillium
spp. have been described as a large group of
fungi which produce cellulolytic enzyme for
many importance industrials. Several articles
reported the production of cellulolytic enzyme
by P. oxalicum (Seeley and Vandemark (1981),
P. pinophilum (Wood et al. (1989), P. brasilianum
(Jorgensen and Olsson, 2006) and Penicillium
sp. (Karthikeyan et al., 2010). In our results, we
isolated P. oxalicum HS1-3 which produced high
carboxymethyl cellulase activity. Moreover,
this P. oxalicum HS1-3 could hydrolyze filter
paper and exhibited the production of betaglucosidase
and avicelase (unpublished data)
at the same time. The synergistic property of
cellulosic enzyme produced from P. oxalicum
HS1-3 is quite promising as this fungus could
hydrolyze cellulosic materials to glucose for
ethanol production.
