“…Ligninolytic fungi play irreplaceable roles in the decomposition of such recalcitrant compounds in litter (Osono, 2007a). Extensive surveys have been carried out comparing the decomposing ability of diverse wood-decomposing ligninolytic fungi (Nillson & Daniel, 1989;Otjen, Blanchette, Effland, & Leatham, 1987;Tanesaka, Masuda, & Kinugawa, 1993;Worrall et al, 1997). In contrast, abilities of diverse fungal species to decompose leaf litter have only sporadically been investigated.…”

Fungi play central roles in leaf litter decomposition as they are capable of actively decomposing lignin and other recalcitrant components in leaf litter that impact the decomposition in terrestrial ecosystems. Quantitative evaluation is lacking, however, regarding the ability of diverse fungi to decompose leaf litter and the variability of ligninolytic activity among fungal taxa. In this comprehensive synthesis, I summarize the data of 1,232 individual pure culture tests conducted under standardized protocols to examine the functional diversity of fungi associated with leaf litter decomposition, with special emphasis on the ligninolytic activity. Fungal strains tested included 218 species in 69 families of Basidiomycota, Ascomycota, and Mucoromycotina that were derived from tropical and temperate forests to polar tundra. Fungal strains were inoculated adjacent to sterilized leaves and other substrata and incubated in the laboratory in order (a) to examine their functional potentialities in terms of the ability to cause mass loss of leaves and decompose recalcitrant components and (b) to explore the effect of litter quality and various environmental factors. The results of these tests revealed that ligninolytic abilities were specifically detected in fungal strains in such families as Mycenaceae and Marasmiaceae in Basidiomycota, and Rhytismataceae and Xylariaceae in Ascomycota. The ligninolytic activity varied among fungal taxa and with the quality and type of substrata, incubation temperature, and external supply of nutrients. This review provides integrative accounts of the functional diversity of ligninolytic fungi associated with leaf litter decomposition and enhances our understanding of the roles of fungal diversity in decomposition processes.

“…As a consequence, special applications such as biomechanical pulping require the use of selective lignin degraders. By contrast, brown-rot fungi include most efficient cellulose-degrading species [26,27]. The white-rot fungi have been studied for treating pulp and paper mill wastewater, cork-boiling wastewater, and other similar wastewaters [28][29][30][31][32].…”

Conventional biological wastewater treatment generates large amounts of low-value bacterial biomass. The treatment and disposal of this excess bacterial biomass accounts for about 40-60% of wastewater treatment plant operational costs. A different form of biomass with a higher value could significantly change the economics of wastewater treatment. Fungi could offer this benefit over bacteria in selected wastewater treatment processes. The biomass produced during fungal wastewater treatment has, potentially, a much higher value than that from the bacterial activated sludge process. The fungi can be used as a protein source and to derive valuable biochemicals. Various high-value biochemicals are produced by commercial cultivation of fungi under aseptic conditions using expensive substrates. Food processing wastewater is an attractive alternative as a source of low-cost organic matter and nutrients to produce fungi with concomitant wastewater purification. This chapter summarizes various findings in fungal wastewater treatment, particularly focusing on creating new byproducts. This chapter also provides an overview on performance of fungal treatment systems under various operational conditions. Important factors such as pH, temperature, hydraulic and solids retention time, nonaxenic and axenic operation, bacterial contamination and others that affect the fungal treatment system are discussed.

“…Cooke was cultivated from basidiospores of a carpophore growing in the mor humus of the same forest. This species can degrade both cellulose and lignin (Norkrans, 1950) and causes a severe bleaching of several types of leaf litter (beech, pine, Taxus) (Watling, 1982), but does not appear to degrade wood (Tanesaka, Masuda & Kinugawa, 1993), and does not form mycorrhizas (Norkrans, 1950).…”

S U M M A R YThe decomposition and the nitrogen and phosphorus mineralization of fresh beech (Fagus sylvatica L.) leaf litter are described. Leaves were buried for up to 6 months in plant containers m which Scots pine (Pxnus sylvestris L.) seedlings were cultivated at a low rate of nutrient addition. The saprotrophic abilities of three ectomycorrhizal fungi, Thelephora terrestris Ehrh.: Fr., Suillus bovinus (L.: Ft.) O. Kuntze and Paxillus involutus (Batsch: Fr) Ft., were compared with the degradation caused by the iittet-decomposing basidiomycete, Lepista nuda (Bull.: Ft.) Cooke. Uninoculated leaves were included as controls. The investigation was performed at two different pH values since substrate pH is supposed to have an effect on the activities of extracellular enzymes of ectomycorrhizal fungi. The enzyme expression might also be largely influenced by the substrate they colonised. The mycorrhizal fungi caused only a low decomposition rate of the litter compared with that of L. nuda, and nitrogen was released only by L nuda. Leaves colonized by mycorrhizal fungi showed no net release of nitrogen; on the contrary, a small accumulation of N in the litter was observed. It therefore seems likely that the ectomyccrrhizal fungi studied do not have the ability to decompose efficiently the ligDOcellulose matrix of the relatively recalcitrant beech Jeaf litter. The degradation of this matrix seems to be essential for the fungi to gain access to the leaf nitrogen pool of fresh beech litter A direct release of nitrogen from organic compounds by ectomycorrhizal fungi seems therefore to be confined to the older litter layers. The beech leaf litter contained an important fraction of easily mineralizable phosphorus. P was not a growth limiting factor m the cultivation system, and could therefore accumulate m the leaf litter colonized by the ectomycorrhizal mycelium.
