| Abstract: | Abstract Transmission electron microscopy of wheat straw cell wall incubated with Pleurotus ostreatus in the presence of glucose or sunflower oil reveals different degradation patterns. Lower lignin content and increased polyphenol-oxidase activity correspond to peculiar features of the substrate at ultrastructural level. Differentiation between cellulose and lignin degradation by electron microscopy might represent a valuable tool to monitor biological delignification during industrial hydrolysis of ligno-cellulose. |
