The macro- and micro-morphological features, mycelial extension rate, enzymatic activities and possible genetic changes were studied in 30 selected strains of basidiomycetes after 10-year cryopreservation on perlite in liquid nitrogen (LN). Comparisons with the same strains preserved by serial transfers on nutrient media at 4 C were also conducted. Production of ligninolytic enzymes and hydrogen peroxide was studied by quantitative spectrophotometric methods, whereas semiquantitative API ZYM testing was used to compare the levels of a wide range of hydrolytic enzymes
