ABSTRACT
The white-rot fungus Bjerkandera sp. BOS55 produced de-novo several aromatic metabolites. Besides veratryl alcohol and veratraldehyde, compounds which are known to be involved in the ligninolytic system of several other white-rot fungi, other metabolites were formed. These included anisaldehyde, 3-chloro-anisaldehyde and a yet unknown compound containing two chlorine atoms. Additionally GC/MS analysis revealed the production of small amounts of anisyl alcohol and 3-chloro-anisyl alcohol. After 14 days, the extracellular fluid of Bjerkandera BOS55 contained 100 microM veratraldehyde and 50 microM 3-chloro-anisaldehyde. This is the first report of de-novo biosynthesis of simple chlorinated aromatic compounds by a white-rot fungus. Anisaldehyde and 3-chloro-anisaldehyde were also produced by Bjerkandera adusta but not by Phanerochaete chrysosporium.
