Characterization of polygalacturonase from the brown-rot fungus Postia placenta

Applied Microbiology and Biotechnology, 1996
Two extracellular isoenzymes of polygalacturonase, isolated from the brown-rot fungus Postia placenta, were purified 342-fold by Mono S cation-exchange chromatography. The temperature optimum ranged from 25 °C to 37 °C, and the pH optimum ranged from 3.2 to 3.9. Apparent pI values of the isoenzymes (3.2 and 3.4) were lower than any previously reported.

Effect of carbon source on the production of oxalic acid and hydrogen peroxide by brown-rot fungus Poria placenta

Journal of Biotechnology, 1995
Oxalic acid and hydrogen peroxide have been suggested to be essential in the degradation of wood carbohydrates by brown-rot fungi. The production of oxalic acid, hydrogen peroxide and endo-β-1,4-glucanase activity by the brown-rot fungus Poria placenta ...

Lignin peroxidase production by a brown-rot fungus Polyporus ostreiformis

Journal of Fermentation and Bioengineering, 1991
Abstract Lignin peroxidase production by a brown-rot fungus Polyporus ostreiformis BU has investigated in stationary culture conditions. A maximum of 50 n kat· l −1 enzyme activity of the culture filtrate was obtained on the 6th d of incubation of the organism in a synthetic liquid medium.

Culture conditions affecting biodegradation components of the brown-rot fungus Gloeophyllum trabeum

Archives of Microbiology, 2003
To determine the liquid culture conditions under which the wood-degrading system of the brown-rot fungus Gloeophyllum trabeum is expressed, enzymes and metabolites from liquid and solid substrate cultures were characterized. Enzymes were analyzed by 2-D gel electrophoresis and also assayed. Growth conditions were varied by using liquid media containing:

Assessment of saccharification efficacy in the cellulase system of the brown rot fungus Gloeophyllum trabeum

Applied Microbiology and Biotechnology, 2010
Brown rot fungi uniquely degrade wood by creating modifications thought to aid in the selective removal of polysaccharides by an incomplete cellulase suite. This naturally successful mechanism offers potential for current bioprocessing applications. To test the efficacy of brown rot cellulases, southern yellow pine wood blocks were first degraded by ...

Proteinases of the Brown-Rot Fungus Postia Placenta

Mycologia, 1992
Proteinase formation by the brown-rot fungus Postia placenta was studied to determine whether differences in proteolytic enzyme production could be correlated with the ability to decay wood.

Characterization and Molecular Cloning of Cellobiose Dehydrogenase from the Brown-Rot Fungus Coniophora puteana

Journal of Bioscience and Bioengineering, 2004
Cellobiose dehydrogenase (CDH) was purified from the brown-rot fungus Coniophora puteana grown in culture containing crystalline cellulose as a carbon source. The purified enzyme gave a single band at 115 kDa on SDS-PAGE and showed a typical flavocytochrome absorption spectrum.

Purification and characterization of a thermophilic xylanase from the brown-rot fungus Gloeophyllum trabeum

Journal of Biotechnology, 1994
A xylanase produced by the brown-rot fungus, Gloeophyllum trabeum, was purified to electrophoretic homogeneity by ion-exchange chromatography and gel filtration. The enzyme had an isoelectric point of 5.0 and molecular mass of 39–42 kDa, respectively.

Polyamine Biosynthesis in the Brown-Rot Fungus Postia placenta

1990
Polyamines are aliphatic polycations that have been shown to be essential for optimal growth and development of a wide variety of living organisms (McCann et al., 1987). Ornithine decarboxylase (ODC) (EC 4.1.1.17) and arginine decarboxylase (ADC) (EC 4.1.1.19) control the rate-limiting steps responsible for biosynthesis of the polyamines putrescine ...

Degradation of cellulose by the major endoglucanase produced from the brown-rot fungus Fomitopsis pinicola

Biotechnology Letters, 2008
An endoglucanase that is able to degrade both crystalline and amorphous cellulose was purified from the culture filtrates of the brown-rot fungus Fomitopsis pinicola grown on cellulose. An apparent molecular weight of the purified enzyme was approximately 32 kDa by SDS-PAGE analysis.
