Abstract

The biodegradative potentialities of a toluene-tolerant Pseudomonas sp. BCNU 154, isolated from waste water, were investigated. Among 16 aromatic substrates tested, cumene, cyclohexane, ethylbenzene, p-xylene, m-xyene, toluene and diphenylether were metabolized. Pseudomonas sp. BCNU 154 degraded aerobically toluene, ethylbenzene, p-xylene and cumene. With toluene competitive degradation occurred after 12 hours, but with p-xylene and cumene, and with ethylbenzene, 90 and 75% degradation occurred after 12 hours of incubation, respectively.

분리된 toluene내성세균 Pseudomonas sp. BCNU 154을 생물분해반응에 적용하고저 그 가능성을 조사하였다. 방향 족화합물 16개을 대상으로 저화능을 조사한 결과 cumene, cyclohexane, ethylbenzene, p-xylen, m-xylen, toluene 그리고 diphenylether가 공시균쥬에 의해 자화됨이 확인 되었다. Pseudomonas sp. BCNU 154는 toluene, ethylbenzene 그리고 p-xylen 그리고 cumene을 호기적으로 분해하였다. Touene은 12시간후에 완전히 분해되었고, p-xylene과 cumene은 12시간배양시 90% 분해되었으며, ethylbenzene은 12시간 배양시 75%가 분해되었다.
