Abstract

Mycelial protoplasts ofGibberella fujikuroi andTrichoderma reesei were prepared using Novozym 234 and linear relationship between the yield of the protoplasts and mycelial concentration up to 2 mg dry mass per mL was observed. The optima for concentration of the enzyme, the age of the culture and the contact time of the enzyme with mycelial cells were 2 g/L, 25h and 10 h, respectively, for both cultures. The frequency of reversion of the individual protoplasts was about 80%.
