Nutrient regulation of extracellular peroxidases in the white rot fungus, Bjerkandera sp. strain BOS55

Applied Microbiology and Biotechnology, 1996
Previous research indicated that the production of peroxidases inBjerkandera sp. strain BOS55 increased under N-sufficient conditions. In this study different organic N sources (amino acids, peptides, proteins) were tested as N supplements. Most N sources significantly enhanced the titres of peroxidases, which increased in parallel with growth.

Degradation of toxaphene by Bjerkandera sp. strain BOL13 using waste biomass as a cosubstrate

Applied Microbiology and Biotechnology, 2006
The white-rot fungus Bjerkandera sp. strain BOL13 was capable of degrading toxaphene when supplied with wood chips, wheat husk or cane molasses as cosubstrates in batch culture experiments. Approximately 85% of toxaphene was removed when wheat husk was the main substrate.

The physiology of anthracene biodegradation by the white-rot fungus Bjerkandera sp. strain BOS55

Applied Microbiology and Biotechnology, 1994
A recently isolated white-rot strain, Bjerkandera sp. strain BOS55, displays high extracellular peroxidase activity, and rapidly degrades polycyclic aromatic hydrocarbons (PAH). In this study, the culture conditions for the biodegradation of the model PAH compound, anthracene, were optimized with respect to O2, N, and C.

Oxidation of lignin in eucalyptus kraft pulp by manganese peroxidase from Bjerkandera sp. strain BOS55

Bioresource Technology, 2001
The white rot fungus Bjerkandera sp. strain BOS55 was shown in previous studies to cause high levels of kraft pulp bleaching and delignification under culture conditions in which manganese peroxidase (MnP) occurs as the dominant oxidative enzyme. In this study, the MnP of Bjerkadera was isolated and tested in vitro with eucalyptus oxygen-delignified ...

Isolation and characterization of a white rot fungus Bjerkandera sp. strain capable of oxidizing phenanthrene

Biotechnology Letters, 2005
Strain BOL13 was selected from 18 fungal strains isolated from an oil-spill contaminated site in Oruro, Bolivia. It was identified as a basidiomycete with high homology to Bjerkandera. The fungus degraded 100 mg phenanthrene l(-1) at 0.17 mg l(-1) d(-1) at 30 degrees C at pH 7. During phenanthrene degradation, a maximum manganese peroxidase activity of

Covalent immobilisation of manganese peroxidases (MnP) from Phanerochaete chrysosporium and Bjerkandera sp. BOS55

Enzyme and Microbial Technology, 2003
Abstract Manganese peroxidases (MnP) from Phanerochaete chrysosporium and Bjerkandera sp. BOS55 were immobilised in glutaraldehyde–agarose gels. Four different strategies were considered concerning the activation of the support (low or high density) and the ionic strength (low or high).

Oxidation of anthracene in water/solvent mixtures by the white-rot fungus, Bjerkandera sp. strain BOS55

Applied Microbiology and Biotechnology, 1995
Polycyclic aromatic hydrocarbons (PAH) are persistent priority pollutants of soil and sediments. The use of white-rot fungi has been proposed as a means of bioremediating PAH-polluted sites. However, higher PAH compounds of low bioavailability in polluted soil are biodegraded slowly. In order to enhance their bioavailability, PAH solubilization, can be

Activation of Kraft Lignin by an Enzymatic Treatment with a Versatile Peroxidase from Bjerkandera sp. R1

Applied Biochemistry and Biotechnology, 2013
Enzymatic lignin activation may be an environmentally friendly alternative to the use of chemicals in the production of wood fibers composites. Most studies on enzymatic activation of lignin for improving the adhesion of lignocellulosic products have been carried out using laccases.

Screening for Pah Degrading White-Rot Fungi: Bjerkandera Sp. Bos55, a Promising New Isolate

1993
New white-rot fungal isolates were screened for their ability to degrade polycyclic aromatic hydrocarbons (PAH). The best isolate. Bjerkandera sp. BOS55, was able to remove 99.2 and 83.1% of anthracene and benzo[a]pyrene supplied at 10 mg L−1 after growing for 28 days in 10 g L−1 glucose media.
