Manganese peroxidase production by Bjerkandera sp. BOS55

Bioprocess Engineering, 2000
The white-rot fungus Bjerkandera sp. BOS55 has been suggested as a good alternative for the production of ligninolytic enzymes, specially Manganese peroxidase (MnP), by its potential ability to degrade complex compounds. However, the application of this fungus requires the complete knowledge of the fermentation pattern in submerged cultures, conditions

The formation of veratryl chloride by Bjerkandera sp. strain BOS55

Phytochemistry, 1997
In the ethyl acetate extract from the extracellular fluid of the mycelium of Bjerkandera sp. BOS55 the presence of veratryl chloride was detected. Addition of deuterated benzoic acid or 4-hydroxybenzoic acid to the culture resulted in the formation of deuterated veratryl chloride.

Evidence for a new extracellular peroxidase Manganese-inhibited peroxidase from the white-rot fungusBjerkanderasp. BOS 55

FEBS Letters, 1992
A novel enzyme activity was detected in the extracellular fluid of Bjerkandera sp, BOS 55. The purified enzyme could oxidize several compounds, such as Phenol red, 2,6-dimethoxyphenol (DMP), Poly R-478, ABTS and guaiacol, with H2O2 as an electron ...

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.

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.

Different fungal manganese-oxidizing peroxidases: a comparison between Bjerkandera sp. and Phanerochaete chrysosporium

Journal of Biotechnology, 2000
Two manganese-oxidizing peroxidases differing in glycosylation degree were purified from fermenter cultures of Bjerkandera sp. They were characterized and compared with the three manganese-oxidizing peroxidase isoenzymes obtained from the well-known ligninolytic fungus Phanerochaete chrysosporium.

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 ...

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

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).
