Starch-degrading enzymes from the brown-rot fungus Fomitopsis palustris

Protein Expression and Purification, 2020
Brown-rot fungi preferentially degrade softwood and cause severe breakdown of wooden structures. At the initial stage of the brown-rot decay, penetrating hyphae of the fungi are observed in ray parenchyma. Since starch grains are known to be present in the ray parenchyma of sapwood, investigation of the functions and roles of the starch-degrading ...

Efficient xylose fermentation by the brown rot fungus Neolentinus lepideus

Enzyme and Microbial Technology, 2012
The efficient production of bioethanol on an industrial scale requires the use of renewable lignocellulosic biomass as a starting material. A limiting factor in developing efficient processes is identifying microorganisms that are able to effectively ferment xylose, the major pentose sugar found in hemicellulose, and break down carbohydrate polymers ...

Bioorganosolv pretreatments of P. radiata by a brown rot fungus (Gloephyllum trabeum) and ethanolysis

Enzyme and Microbial Technology, 2010
Abstract Pinus radiata wood chips were pretreated with the brown rot fungus Gloephyllum trabeum for 3 weeks followed by an organosolv delignification with ethanol:water mixture at pH 2. The organosolv process was assessed using biotreated material that showed a high viscosity loss and a mass loss ranging from 6% to 8%. The experiment was designed

Purification and characterization of a thermostable xylanase from the brown-rot fungus Laetiporus sulphureus

Journal of Bioscience and Bioengineering, 2009
A thermostable extracellular xylanase was purified and characterized from brown-rot basidiomycete Laetiporus sulphureus, cultivated on biologically pretreated Pinus densiflora biomass. After three consecutive purification steps using DEAE, Mono Q, and Superdex 75 columns, the xylanase specific activity was found to be 72.4 U/mg, nine fold higher than ...

Microbodies in the Brown Rot Fungus Poria contigua

Zentralblatt für Bakteriologie: I. Abt. Originale C: Allgemeine, angewandte und ökologische Mikrobiologie, 1980
Summary Using the diaminobenzidine (DAB) reaction catalase activity could be demonstrated cytochemically in cytoplasmic structures of Poria contigua bearing the general ultrastructural features of microbodies. These kidney-shaped compartments were associated with a densely packed coherent membrane system.

Biodegradation of polyvinyl alcohol by a brown-rot fungus, Fomitopsis pinicola

Biotechnology Letters, 2013
A brown-rot fungus, Fomitopsis pinicola, degraded polyvinyl alcohol (PVA) in quartz sand but not in liquid culture. From gel permeation chromatography analysis, the high-molecular-weight fraction of PVA was decreased by the action of F. pinicola but the coloration of the culture filtrate with I2 solution increased.

Effect of biodegradation on thermogravimetric and chemical characteristics of hardwood and softwood by brown-rot fungus

Bioresource Technology, 2016
The thermogravimetric and chemical characterization of hardwood Eucalyptus urophylla (Ep) and softwood Pinus massoniana (Mp) pretreated by brown-rot fungus Gloeophyllum trabeum were investigated. The results indicated that the brown-rot fungus pretreatment can optimize the thermal decomposition and decrease the initiation temperatures (8-11°C lower) of

Enhancement of autofluorescence of the brown-rot fungus Piptoporus betulinus by metal ions

Folia Microbiologica, 2010
The autofluorescence (primary fluorescence, AF) of agar cultures of the brown-rot fungus Piptoporus betulinus was investigated in Zeiss Jenalumar and Nikon Eclipse 8201 fluorescence microscopes at various excitations. The strongest AF of hyphae was found in minimal medium with glucose, where the hyphae exhibited green AF at violet (450 nm) excitation ...

Multipath effects of berberine on peach Brown rot fungus Monilinia fructicola

Crop Protection, 2019
Abstract The brown rot disease caused by fungus Monilinia fructicola severely reduces the yield of peach and other stone fruits. Earlier, we found that berberine (BBR), one of isoquinoline alkaloids, strongly halts the growth of M. fructicola. However, the underlying mechanisms remain unclear. Here we report that BBR inhibits M.

Monilia mumecola, a new brown rot fungus on Prunus mume in Japan

Journal of General Plant Pathology, 2004
In 1982, an anamorphic fungus in the genus Monilia was first isolated as the causal agent of brown rot disease of Japanese apricot or mume (Prunus mume) in Oita Prefecture, Kyushu, Japan. Inoculation of flowers, shoots, and fruit of P. mume with the fungus reproduced brown rot disease symptoms similar to those found in nature.
