Abstract 1. FourPseudomonas strains, anAchromobacter sp., threeNocardia strains,Mycobacterium coeliacum and aBacillus sp., grown on either phenol or benzoic acid as sole carbon source, were tested for co-oxidation of monochlorophenols and monochlorobenzoates respectively. 2. ThePseudomonas spp.,Nocardia spp.,M. coeliacum and theBacillus sp. showed O2-uptakes in the presence ofo-, m- orp-chlorophenol and oxidised them to either 3- or 4-chlorocatechol. 3. Benzoate-grown cells of the threeNocardia spp. and three of the pseudomonads absorbed O2 only in the presence ofm-chlorobenzoate, 4-chlorocatechol being identified as the oxidation product in two cases. One pseudomonad gave some O2-uptake also in presence ofp-chlorobenzoate. 4. Benzoate-grownBacillus cells gave O2-uptakes with eitherm- orp-chlorobenzoate and the former was oxidised to 5-chloro-2,3-dihydroxybenzoic acid via 5-chlorosalicylic acid, thus representing a novel metabolic pathway.
