Abstract
The measurement of growth rate of three isolates—P14, P15 and P19 (obtained after regeneration of protoplasts of the control strain) with significantly higher (P14, P19) or lower (P15) activity of laccase than the control strain (P. ostreatus florida F6) revealed similar patterns for P14 and P19; P15 had a higher growth rate and the highest rate was observed in the control strain. The rate of mineralization of14C-lignin on SSF (perlite) by strains F6 and P15 was almost the same and it was higher than that of P14 and P19 strains. The enzyme pattern of the individual isolates, studied by gel electrophoresis and activity staining of laccase, did not show any difference in isozyme patterns of the isolates, but there were differences in the level of gene expression.
