Summary Thirteen different strains of micro-organisms able to grow on phenol as a major carbon source were isolated from soil. Among these there were six bacteria, three yeasts, and four mycelial fungi. The oxidation of phenol and catechol by these organisms was studied using the manometric technique and the reaction products were identified by spectrophotometry. In most of the isolated strains, the pathway phenol → catechol →cis, cis-muconate muconate is the main route of phenol degradation. In one of our bacterial strains the extradiol type of catechol cleavage exists together with the intradiol ring fission. In two of the strains investigated, the pattern of oxygen consumption in the presence of phenol and catechol indicated that catechol was not the first intermediate (or not the only one) in the degradation of phenol by these strains. Also the spectra of the oxidation products indicated the presence of a reaction product different from eithercis,cis-muconate or α-hydroxy muconic semi-aldehyde. Washed cells of the majority of the strains accumulated coloured products (possibly quinones) when incubated with phenol or catechol.
