Abstract:

The optimal conditions for the lywallzyme hydrolysis of the cultured mycelia of Pleurotus eryngii for protoplast production were investigated by single factor and orthogonal array design methods. Results showed that the optimal values of hydrolysis conditions were as follows: substrate concentration 133 mg/mL, enzyme dosage 1.0% and pH 6.0 for a hydrolysis duration of 2.5 h at 30 ℃. The hydrolysate obtained under such conditions exhibited a protoplast density of up to 6.34 × 107 cells/mL.

Key words: lywallzyme, Pleurotus eryngii, protoplasts, enzymolysis conditions, orthogonal array design
