Variation in Molecular Weight of cis-1,4-polyisoprene by White Rot Fungus Ceriporiopsis Subvermispora

Properties of laccase isoenzymes produced by the basidiomycete Ceriporiopsis subvermispora.

Laccase is one of the ligninolytic enzymes found in liquid cultures of the fungus Ceriporiopsis subvermispora in defined medium. As an approach to a clarification of the role of laccases during the attack on lignin by the fungus, the enzyme has been characterized further. The levels of this phenol oxidase increase 2-fold in the presence of p-anisidine and are severely affected when addition of ...

Degradation of cis-l,4-Polyisoprene Rubbers by White Rot Fungi and Manganese Peroxidase- Catalyzed Lipid Peroxidation

Lignin-degrading peroxidases from the genome of the selective ligninolytic fungus Ceriporiopsis subvermispora*

Background: The first genome of a selective lignin-degrader is available. Results: Its screening shows 26 peroxidase genes, and five were heterologously expressed and catalytic properties investigated. Conclusion: Two new peroxidases oxidize simple and dimeric lignin models and efficiently depolymerize lignin. Significance: Although lignin peroxidase and versatile peroxidase had not been report...

Biodegradation of ciprofloxacin by white rot fungus Pleurotus ostreatus

Unrestricted and reckless use of antibiotics has resulted in their accumulation in environment. This, in turn, has led to the emergence of multiple drug-resistant microbes. The present study focuses on degradation of ciprofloxacin (CIP) by an edible white rot fungus Pleurotus ostreatus. Effect of CIP was determined on radial growth and biomass of P. ostreatus. Titrimetric and spectrophotometric...

Biodegradation of 2,4,6-Trinitrotoluene by White-Rot Fungus Irpex lacteus

White-rot fungus Irpex lacteus degraded TNT significantly in proportion to the culture time. After 48 h incubation, about 95% of TNT was degraded. Two reduced metabolites were identified as 4-amino-2,6-dinitrotoluene (4-ADNT) and 2-amino-4,6-dinitrotoluene (2-ADNT) which was further degraded.
