aStrains were cultured on MM medium supplemented with cellobiose (MM Cellobiose medium) or CMC (MM CMC medium) for 120 hrs at 37ºC and 150 rpm. Values followed by the same letters in the columns are not significantly different at 5% probability level. Means were calculated for three replicates.
b Nd: not determined.
* The values in the column are significantly different at 5% probability level.
