TLDR
Recent advances in the various biological treatments that can turn these three lignicellulose biopolymers into alternative fuels are reviewed and biotechnological innovations based on natural delignification and applied to pulp and paper manufacture are outlined.Abstract:
In nature, cellulose, lignocellulose and lignin are major sources of plant biomass; therefore, their recycling is indispensable for the carbon cycle. Each polymer is degraded by a variety of microorganisms which produce a battery of enzymes that work synergically. In the near future, processes that use lignocellulolytic enzymes or are based on microorganisms could lead to new, environmentally friendly technologies. This study reviews recent advances in the various biological treatments that can turn these three lignicellulose biopolymers into alternative fuels. In addition, biotechnological innovations based on natural delignification and applied to pulp and paper manufacture are also outlined.read more

Biodegradation of lignin in a compost environment: a review
TL;DR: The optimum temperature for thermophilic fungi is 40-50°C which is also the optimal temperature for lignin degradation in composting as discussed by the authors, however, very little is known about the degradation by mixed microbial compost populations.

Molecular and biotechnological aspects of xylanases
TL;DR: Many lines of evidence suggest that xylanases operate via a double displacement mechanism in which the anomeric configuration is retained, although some of the enzymes catalyze single displacement reactions with inversion of configuration.
