Activity of cellulolytic enzymes cultures Stereum hirsutum (Wild.) Gray, different nuclear status, depending on the substrate have been studied. The most productive by synthesis endoglucanases monokaryotic cultures of Sh1-4 and Sh7-2 were determined. It is found that nutrient medium containing filtering paper is optimal for synthesis of cellulase (culture Sh1-4, maximum of cellulolytic activity is 319 μМ/mg, culture Sh7-2 — 101 μМ/mg). Maximum of cellulolytic activity at cultivation with sawdust of trees for culture Sh1-4 observed at the 10th day was 142 ?М/mg (oak sawdust), for culture Sh7-2 at the 20th days it was 34 μМ/mg (ash-tree sawdust). Study of quality cellulolytic enzymes enabled to establishe presence of four exoenzymes of Cx complex with a relative electrophoretic mobility of 0.22; 0.24; 0.47; 0.74. Enzyme with relative electrophoretic mobility 0.47 showed high concentration and activity.

Key words: cellulolytic enzymes, Stereum hirsutum, monokaryotic cultures, electrophoresis of proteins.
