[Identification of genes encoding ligninolytic enzymes in naturally occurring basidiomycete isolates]

The presence of genes encoding lignin peroxidase, laccase, and manganese peroxidase was assessed in more than 20 types of polypore fungi collected in the woods of Kirov oblast; the fungi studied had not been previously characterized with regard to ligninolytic enzyme production. Fifteen isolates of eleven basidiomycete species were shown to contain genes coding for all three ligninolytic enzymes. Genes coding for these enzymes were detected in D. mollis, D. quercina, F. pinicola, G. trabeum, G. lucidum, H. fasciculare, L. betulina, P. betulinus, P. igniarus, P. pomaceus, P. pini, and P. cinnabarinus for the first time.
