Discovery and characterization of a novel p-hydroxybenzoate-m-hydroxylase, protocatechuate 3,4 ring-cleavage dioxygenase and hydroxyquinol 1,2 ring-cleavage dioxygenase from Aspergillus niger

The aim of this study was to find candidate genes in A. niger involved in the degradation of benzoic acid. Overall design: Transcriptome data on aromatic compounds was used to find candidate genes encoding benzoic acid metabolic enzymes
