Culture growth and xylanase production were assessed by feeding
the culture with various carbon sources at 40 C and pH 7.0.
Either birchwood xylan, beechwood xylan, sawdust, wood chips
or palm oil fiber was used as a carbon source in the liquid medium.
After 6 days of culture growth, enzyme activity was assessed. To
investigate the influence of temperature, cultures were assayed
at different temperatures ranging from 25 to 50 C. Culture growth
and enzyme production were also evaluated at various initial pHs
from 5.0 to 11.0 at 40 C.
