title: Catabolism of single ring aromatic acids by four Aspergillus species.
abstract: Four species of the genus Aspergillus, viz A. fumigatus, A. japonicus, A. niger and A. terreus, decarboxylated, demethoxylated and ring-cleaved aromatic compounds but to different extents. Decarboxylation of vanillate occurred before ring-cleavage, which preceded the release of 14CO2 from the methoxyl group. A large proportion of labelled carbon from the ring of ferulate and vanillate was found in particulate or trichloracetic acid precipitable material of homogenized fungal mycelium. The four Aspergillus species contained vanillate-inducible protocatechuate-3,4-dioxygenase and catechol-1,2-dioxygenase activities.
