Fourteen strains of white-rot basidiomycetes belonging to eight species of two genera (Inonotus and Pholiota) were tested for their ability to maintain the production of laccase, peroxidase and manganese-dependent peroxidase (enzymes involved in lignin biodegradation) after a short-time preservation in liquid nitrogen with different cryoprotectives (glycerol, dimethyl sulfoxide). No negative effect of cryopreservation or the used cryoprotective on production of the ligninolytic enzymes was found in the fungi tested.
