Effect of glucose, CSL, GL levels
In examining effect of cultivation medium composition on
the bioconversion process, different levels of either
glucose, CSL or GL were used (Figures. 1, 2 and 3,
respectively). The low level of glucose (0.5 %) supported
maximum GL bioconversion activity (44.45 %), while
increase of glucose level over the latter concentration
resulted in a gradual decrease in GL bioconversion
efficiency. The enhanced bioconversion efficiency in the
presence of glucose might be due to increased growth of
