Methyl alcohol in the concentration of 25 ml kg-1 of the substrate gave maximum production i.e. 45.85 g kg-1 while when ethanol was added the maximum production achieved was 40.65 g kg-1. The sugar consumption was 111g kg-1 and 110 g kg-1 respectively. The kinetic parameters such as product yield coefficient (Yp/x), and volumetric rate for product formation (Qp) and substrate consumption (Qs) were also found to be significant at 25 ml kg-1 methanol concentration.
