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 μM veratraldehyde and 50 μM 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 .
