Exotic litter of the invasive plant Ligustrum lucidum alters enzymatic production and lignin degradation by selected saprotrophic fungi
Chemical changes in leaf input to forest soils have been reported to affect decay processes. In this work, litter mass loss and decomposition constants (k) during 200 days in solid-state fermentation of the native tree Celtis tala Gill. ex Planch. and the exotic one Ligustrum lucidum Ait. with three...
