Abstract
The enzyme phenol hydroxylase (EC 1.14. 13.7) was determined and characterized in crude extracts of Rhodococcus sp. P 1. This enzyme catalyzed the first step of phenol degradation. It was inducible, had a pH optimum of 7.9 and ad temperature optimum at 20 °C and catalyzed also the hydroxylation of some other phenolic compounds.
