Abstract:Phanerochaete chrysosporium were used to investigate ulating effects of coal slurry with
thogonal study results indicate that Phanerochaete chrysosporium
have
good effect
in
ulating coal slurry,the bination of Phanerochaete chrysosporium culture time is 2 days,
coagulant is 2 mL,and bacilli volume is 2 mL,the kind ulent is broken liquid,the pH valud is 6.
The result of FTIR shows that the biological
extract
of Phanerochaete ehrysosporium contains
lot of acid—
ic harides that has the effect of
