Abstract: | Variability of production of all tested ligninolytic enzymes (laccase, peroxidase and manganese-dependent peroxidase) was
substantially higher in isolates derived from basidiospores of strain F6 of the white-rot basidiomycetePleurotus ostreatus than the relatively low variability of the dikaryotic mycelial colonies of this strain, and also higher than the variability
of protoplast-derived isolates of the same strain. The difference was caused mainly but not completely by the monokaryotic
nature of the isolates. To reach the best fructification of the fungus, two fructification media were chosen from twenty two
tested and a modified technique of fructification was used. |
