Ligninase of Phanerochaete chrysosporium
This study examined the ligninase-catalysed degradation of lignin model compounds representing the arylglycerol ,-aryl ether substructure, which is the dominant one in the lignin polymer. Three dimeric model compounds were used, all methoxylated in the 3and 4-positions of the arylglycerol ring (ring A) and having various substituents in the ,-ether-linked aromatic ring (ring B), so that competi...
متن کاملNucleotide sequence of a ligninase gene from Phanerochaete chrysosporium.
Lignin biodegradation is catalyzed in part by ligninases, also known as lignin peroxidases (1-4). We have cloned and sequenced the gene encoding ligninase isozyme H8 from the white-rot fungus Phanerochaete chrysosporium. The gene is interrupted by eight introns, ranging in size from 49 to 69 bp, which are distributed throughout the gene. Putative transcriptional control signals (underlined) inc...
متن کاملFactors Involved in the Regulation of a Ligninase Activity in Phanerochaete chrysosporium.
The regulation of an H(2)O(2)-dependent ligninolytic activity was examined in the wood decay fungus Phanerochaete chrysosporium. The ligninase appears in cultures upon limitation for nitrogen or carbohydrate and is suppressed by excess nutrients, by cycloheximide, or by culture agitation. Activity is increased by idiophasic exposure of cultures to 100% O(2). Elevated levels of ligninase and, in...
متن کاملDecolorization of Molasses Waste Water from an Alcoholic Fermentation Process with Phanerochaete Chrysosporium Involvement of Ligninase
Waste water from a molasses alcoholic fermentation plant (MWW) was treated biologically with Phanerochaete chrysosporium. The ability of this white-rot fungus to degrade the dark colored pigments present in MWW and the consequent decrease the effluent's color was examined. The Optimum concentration of MWW for color removal was determined and set at the ratio of 1:10. The color changes durin...
متن کاملHalotolerance, ligninase production and herbicide degradation ability of basidiomycetes strains
Fungi have been recently recognized as organisms able to grow in presence of high salt concentration with halophilic and halotolerance properties and their ligninolytic enzyme complex have an unspecific action enabling their use to degradation of a number of xenobiotic compounds. In this work, both the effect of salt and polyols on growth of the basidiomycetes strains, on their ability to produ...
