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 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...
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 کاملCredit Search and Credit Cycles
The supply and demand of credit are not always well aligned and matched, as is reflected in the countercyclical excess reserve-to-deposit ratio and interest spread between the lending rate and the deposit rate. We develop a search-based theory of credit allocation to explain the cyclical fluctuations in bank reserves, the interest spread, as well as credit rationing. We show that search frictio...
متن کاملCredit contagion and credit risk
We study a simple, solvable model that allows us to investigate effects of credit contagion on the default probability of individual firms, in both portfolios of firms and on an economy wide scale. While the effect of interactions may be small in typical (most probable) scenarios they are magnified, due to feedback, by situations of economic stress, which in turn leads to fatter tails in loss d...
