ABSTRACT: Optimation biokraft
of fungi P. Chrysosporium through elongated
incubation time on mixed stem
and branch waste
mangium is a
solution to solve
the environmental pollution problem,
low quality of
pulp and limited
raw material. Effect
of P. Chrysosporium 10 % concentration and 45 days incubation time on
pre research could not decrease lignin optimally and exstractive degradation
had not occured yet. The aims of the study
were to observe the
effect of incubation
time extension, and to determine
the best incubation time of P.
Chrysosporium applied at 10 % concentration based on the chemical component
percentage, 45, 60 and 75 days on mixed
stem and branch as raw material for pulp.
Results showed that
increasing incubation time
decreased extractive and
lignin content and
increased holocelulosa and
alpha celulosa content.
Mixed stem and
branch with 10% amount and 75 day
incubation time of P.
Chrysosporium gave the best results for
raw material of pulp.
Key words:
biokraft, Phanerochaete crysosporium,
chemical component of
mangium, pulp
