Manganese regulation of veratryl alcohol in white rot fungi and its indirect effect on lignin peroxidase
Article Abstract:
Manganese (Mn) controls the biosynthesis of veratryl alcohol in white rot fungus, and if the concentration of Mn is low, the formation of veratryl alcohol is inhibited. Veratryl alcohol is necessary for the breakdown of lignin and its compounds by lignin peroxidase (LiP). Mn indirectly affects the amount of LiP formed by the cell because of its effect on the formation of veratryl alcohol. Nitrogen does not have any effect on veratryl alcohol synthesis because if the concentration of Mn remains constant, there is no change in the amount of alcohol formed in different nitrogen concentrations.

Role of organic acids in the manganese-independent biobleaching system of Bjerkandera sp. strain BOS55,
Article Abstract:
The role of simple organic acids on the stimulation of manganese-independent biobleaching of eucalyptus oxygen-delignified kraft pulp (OKP) was investigated. While an inverse relationship was obtained with the glycolate concentration and the kappa number or delignification, pulp brightness showed a direct association with optimum glycolate concentration. Although biobleaching occurred in both the control and experimental cultures in the first period, it stopped in the control during the second stage.

Biodegradation of polycyclic aromatic hydrocarbons by new isolates of white rot fungi
Article Abstract:
Newly isolated white rot fungi were tested for the biodegradation of polycyclic aromatic hydrocarbons (PAH). All of the strains tested degraded anthracene. Whereas strains from the genera Bjerkandera, Phanerochaete and Ramaria accumulated anthraquinone, Trametes strains were able to degrade anthraquinone. The best degrader of anthracene and benzo(a)pyrene was Bjerkandera sp. strain Bos 55. It was demonstrated that the polymeric dye Poly R-478 was useful in screening for promising PAH degraders.
