Abstract
The Penicillium strain Bi 7/2 able to grow on phenol as sole source of carbon and energy was isolated from a contaminated soil in Bitterfeld (East Germany). The strain is adapted to high phenol concentrations. Spores germinated still at a phenol concentration of 1.5 g/l. Phenol is degraded by the ortho-pathway with catechol as first intermediary product. The Penicillium strain metabolizes 4-, 3- and 2-chlorophenol with decreasing rates with phenol or glucose as cosubstrate. In the case of 4-chlorophenol 4-chlorocatechol was detected as intermediary product, further degraded as indicated by release of about 35% of the bound chlorine of the aromatic molecule. The strain also cometabolically metabolizes 4-, 3- and 2-nitrophenol. The final product of 3- and 4-nitrophenol is 4-nitrocatechol.
