Abstract

Two Achromobacter strains capable of utilizing 2,2-dimethylheptane or tertbutylbenzene as the sole carbon and energy source were isolated from waste-water. Pivalic acid was found in the cultures of Achromobacter A1 containing 2,2-dimethylheptane. From cultures of Achromobacter A2 in the presence of tertbutylbenzene, a diol was isolated and identified as 2,3-dihydro-2,3-dihydroxytertbutylbenzene. Evidence for meta cleavage of the aromatic ring and for accumulation of pivalic acid in the cultures was also obtained. A metabolic pathway for tertbutylbenzene is suggested.

摘要

从废水中分离出两株能够利用2,2-二甲基庚烷或叔丁基苯作为唯一碳源和能源的无色杆菌菌株。在含有2,2-二甲基庚烷的无色杆菌A1培养物中发现了新戊酸。在叔丁基苯存在的情况下,从无色杆菌A2的培养物中分离出一种二醇,并鉴定为2,3-二氢-2,3-二羟基叔丁基苯。还获得了芳香环间位裂解以及培养物中新戊酸积累的证据。提出了叔丁基苯的代谢途径。
