Abstract
The objective of this study is to determine the growth rate of TriclJoderma reesei from batch fermentation in liquid medium by using single substrate as carbon source which were cassava waste and rice straws. It was found that 12. 5 % and 8.2 % by weight of maximum reducing sugar obtained from 60 g/l, of each substrate in liquid medium fermented with 0041 g/L of Ttichodetmu reesei RMUTTO I at pH 5 and shaking speed of 120 rpm at room temperature (32 degree Celsius). for 7 day s and 5 days fermentation time of cassava waste and rice straws respectively; the maximum specific growth rate of TriclJodenna reesei ([mu]max) in cassava waste and rice straws fermentation is 0.97 per day and 0.16 per day and saturation constant (K[subscript s]) is 143.13 and 36.35 gram/liter respectively.
