where X1 was inoculation rate of A.sojae, X2 was inoculation rate of
T.harzianum, and X3 was agitation speed that constitute the significant
factors effective on bioethanol production. As depicted in
Fig. 2, higher concentrations of inoculation rates of T.harzianum and
A.sojae 6% (w/v) and agitation speed around 200 rpm led to
maximum amount of bioethanol. On the other hand inoculation
rate of S.cerevisiae and aeration method did not change bioethanol
production, significantly.
