Microbial Degradation of Lignocellulose: the Lignin Component

Microbial degradation of lignocellulose: the lignin component.

A new procedure was developed for the study of lignin biodegradation by pure or mixed cultures of microorganisms. Natural lignocelluloses were prepared containing C in primarily their lignin components by feeding plants l-[U-C]phenylalanine through their cut stems. Lignin degradation was observed in numerous soils by monitoring evolution of CO(2) from [C]lignin-labeled oak (Quercus albus), mapl...

Lignin degradation: A microbial approach

Metabolic control of lignocellulose degradation by lignocellulose-degradation microbial community MC1

This study was to reveal the limiting factors of lignocellulose degradation and further improve the potential degradation of microbial community MC1, by pH manual adjustment (pHMA) and culture medium partial replacement (CMPR) during the process of rice straw degradation. The results indicated degradation rate in control (5% rice straw) increased, ranging from 33.3 to 67.5% via pHMA method, and...

Boosting LPMO-driven lignocellulose degradation by polyphenol oxidase-activated lignin building blocks

BACKGROUND Many fungi boost the deconstruction of lignocellulosic plant biomass via oxidation using lytic polysaccharide monooxygenases (LPMOs). The application of LPMOs is expected to contribute to ecologically friendly conversion of biomass into fuels and chemicals. Moreover, applications of LPMO-modified cellulose-based products may be envisaged within the food or material industry. RESULT...
