Aromatic hydrocarbons are known to be recalcitrant, so that they have been concerned as pollutant chemicals. Microorganisms play a major role in the breakdown and mineralization of these compounds. However, the kinetics of the biodegradation process may be much slower than desired from environmental consideration. The biodegradation of aromatic hydrocarbons is conducted by oxidation to produce catechol as a common intermediate which is metabolized for carbon and energy sources. In this study, a bacterial isolate capable of degrading several aromatic hydrocarbons was isolated from the contaminated wastewater of Yeocheon industrial complex. On the basis of biochemical characteristics and major cellular fatty acids, the isolate was identified as Pseudomonas putida Z104. The strain Z104 can utilize benzoate and catechol as the sole carbon and energy sources via a serial degradative pathway. The strain degraded actively 0.5 mM catechol in MM2 medium at pH 7.0 and 3$0^{circ}C$.
