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

Culture conditions affecting biodegradation components of the brown-rot fungus Gloeophyllum trabeum. Varela, Elisa; Mester, Tunde; Tien, Ming (Department of Biochemistry and Molecular Biology, Pennsylvania State University, University Park, PA 16802, USA). Archives of Microbiology, 180(4), 251-256 (English) 2003 : Springer-Verlag. CODEN: AMICCW.Chemicals with cas numbers 3117-03-1 and 50-99-7 also play role. ISSN: 0302-8933. DOCUMENT TYPE: Journal CA Section: 10 (Microbial, Algal, and Fungal Biochemistry) To det. the liq. culture conditions under which the wood-degrading system of the brown-rot fungus Gloeophyllum trabeum is expressed, enzymes and metabolites from liq. and solid substrate cultures were characterized. Enzymes were analyzed by 2-D gel electrophoresis and also assayed. Growth conditions were varied by using liq. media contg.: (1) low carbon, low nitrogen, (2) low carbon, high nitrogen, (3) high carbon, low nitrogen, or (4) high carbon, high nitrogen. The protein arrays expressed under the four conditions were very similar, and endo-1,4-b-glucanase (detected by 2-D gels) activity along with b-glucosidase, xylanase, and NADH/quinone oxidoreductase activities were detected. Maximal expression of the hydrolytic enzymes was obsd. in high carbon/high nitrogen medium, whereas the highest oxidoreductase activity was in the high carbon low nitrogen medium. Oxalate and 2,5-dimethoxybenzoquinone were detected under all culture conditions, with higher prodn. in high carbon/low nitrogen medium. Cultures grown in this medium also yielded the highest rate of hydroxylation of p-hydroxybenzoic acid, yielding protocatechuic acid, a product of hydroxyl radical attack. .
