Evolution of lignocellulose decomposition was one of the most ecologically important innovations in fungi. White-rot fungi in the Agaricomycetes (mushrooms and relatives) are the most effective microorganisms in degrading both cellulose and lignin components of woody plant cell walls (PCW). However, the precise evolutionary origins of lignocellulose decomposition are poorly understood, largely ...
Ectomycorrhizal fungi play a key role in mobilizing nutrients embedded in recalcitrant organic matter complexes, thereby increasing nutrient accessibility to the host plant. Recent studies have shown that during the assimilation of nutrients, the ectomycorrhizal fungus Paxillus involutus decomposes organic matter using an oxidative mechanism involving Fenton chemistry (Fe H2O2 H ¡ Fe ̇OH H2O), s...
Fungi and bacteria are the major organic matter (OM) decomposers in aquatic ecosystems. While bacteria are regarded as primary mineralizers in the pelagic zone of lakes and oceans, fungi dominate OM decomposition in streams and wetlands. Recent findings indicate that fungal communities are also active in lakes, but little is known about their diversity and interactions with bacteria. Therefore,...
White rot fungi produce extracellular phenoloxidases and can decompose lignin efficiently. Elfvingia applanata has been successfully applied for the bioconversion of bisphenol A, suggesting the usefulness of white rot fungi for bioremediation. In order to attain real bioremediation, the recycling of ecomolecules in the ecosystem is important. The sophisticated symbiotic system of white rot fung...
The efficiency and dynamics of simultaneous kenaf biomass decomposition by basidiomycetous fungi and actinobacteria were investigated. After 8weeks of incubation, up to 34wt.% of the kenaf biomass was degraded, with the combination of fungi and bacteria being the most efficient. Lignin decomposition accounted for ∼20% of the observed biomass reduction, regardless of the culture used. The remain...
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...
Introduction: Fungi are placed in the kingdom fungi according to the five concept of Whitteker .Microbiologist use the term fungus. Eukaryotic, achlorophyllous,spore bearing organism with absorptive nutrition that reproduce both sexually and asexually and usually have filamentous structure whose cells wall generally contain cellulose. Fungi reproduce via spores, which are often produced on spec...
