title: Hydroxylation of benzoate and its chlorinated derivatives in Aspergillus niger.
abstract: Comparison of the properties of a purified benzoate-4-hydroxylase, using benzoic acid and its chlorinated derivatives as substrate, suggests that the same enzyme operates during the initial hydroxylation of benzoate, 2-chlorobenzoate (2-cba), and 3-chlorobenzoate (3-cba) in A.niger.
