Soil basidiomycetes isolated from KBS were examined for the distribution and relative abundanceÕs of lignin peroxidase, (LIP), manganese dependent peroxidase (MNP) and laccase (LAC). The abundanceÕs of these ligninolytic enzymes produced by 25 isolates were correlated to two soil treatments; physical perturbation (tillage) and diversity (species richness and heterogeneity) of plant material inputs. LAC was produced by 90% of all isolates. MNP was produced by 40% of all isolates. No isolates produced LIPs although the potential for the production was evidenced through molecular probing. 75% of all isolates from the tilled soils produced LAC in vitro and 62.5% produced MNP. 40% of the isolates from the no-till soils produced LAC in vitro and 33.3% produced MNP. 82.5% of the isolates from the successional plant treatment soils produced LAC in vitro and 62.5% produced MNP. These data support the hypotheses that basidiomycetes isolated from a physically disturbed site have a higher distribution of ligininolytic enzymes than isolates from a non-disturbed site and basidiomycetes isolated from a soil with a high diversity of plant material inputs have a higher distribution of ligninolytic enzymes than those isolated from a soil with a lesser diversity of plant material inputs.Return to ContentsBack to meeting | Show |
