Cellulose utilization in forest litter and soil: identification of bacterial and fungal decomposers.
Organic matter decomposition in the globally widespread coniferous forests has an important role in the carbon cycle, and cellulose decomposition is especially important in this respect because cellulose is the most abundant polysaccharide in plant litter. Cellulose decomposition was 10 times faster in the fungi-dominated litter of Picea abies forest than in the bacteria-dominated soil. In the ...
متن کاملIsolation of fungal cellobiohydrolase I genes from sporocarps and forest soils by PCR.
Cellulose is the major component of plant biomass, and microbial cellulose utilization is a key step in the decomposition of plant detritus. Despite this, little is known about the diversity of cellulolytic microbial communities in soil. Fungi are well known for their cellulolytic activity and mediate key functions during the decomposition of plant detritus in terrestrial ecosystems. We develop...
متن کاملSynergistic Degradation of Lignocellulose by Fungi and Bacteria in Boreal Forest Soil
Boreal forests contain an estimated 28% of the world’s soil carbon, and currently act as a significant global carbon sink. Plant-derived lignocellulose is a major component of soil carbon, and its decomposition is dependent on soil bacteria and fungi. In order to predict the fate of this soil carbon and its potential feedbacks to climate change, the identities, activity, and interactions of soi...
متن کاملBiodegradation of polystyrene, poly(metnyl methacrylate), and phenol formaldehyde.
The biodegradation of three synthetic 14C-labeled polymers, poly(methyl methacrylate), phenol formaldehyde, and polystyrene, was studied with 17 species of fungi in axenic cultures, five groups of soil invertebrates, and a variety of mixed microbial communities including sludges, soils, manures, garbages, and decaying plastics. Extremely low decomposition rates were found. The addition of cellu...
متن کاملProduction of Lignocellulolytic Enzymes by Mushrooms
Biopolymers contained within or derived from plant biomass form by far the largest pool of soil carbon. The decomposition of lignocellulose in the soil environment thus attracts considerable attention. Lignocellulose is composed mainly of the polysaccharidic polymers cellulose and hemicelluloses, and the polyphenolic polymer lignin. During transformation in soils, humic substances (humus, humic...
