Trichoderma reesei was grown for 180h in batch culture in an 8 liter stirred fermenter using a glucose-rich medium. Concentrations of glucose, ammonia, cell dry weight, debris and lipid are presented for two runs. Cell dry weights reached 26.9g/L and 19.6g/L in these runs. The debris from solvent-extracted cells was chitin which accumulated to greater than 75% of the final cell dry weights.
