Abstract
Twenty-six yeast strains, representative of different yeast genera, were tested for their sensitivity to crude extracellular cellulolytic enzyme complexes obtained from the fungusTrichoderma reesei QM 9414 and its mutants M 6 and MHC 22 (Microcrystalline cellulose was the sole carbon source.) Practically all the yeast strains tested were found to be sensitive, exhibiting signs of cellwall weakening and lysis during prolonged incubation with the emzymes fromTrichoderma. Under growth conditions, the effect of cellulolytic enzymes on yeast cells and their growth rates was much less pronounced. However, at increased cellulase concentrations (5 mg/ml) in the growth medium, lysis of stationary phase yeast cells was observed.
