This report describes the metabolism of 6,10,14-trimethylpentadecan-2-one by a denitrifying bacterium (Marinobacter sp. strain CAB) isolated from marine sediments. Under aerobic and denitrifying conditions, this strain efficiently degraded this ubiquitous isoprenoid ketone. Several bacterial metabolites, 4,8,12-trimethyl-tridecan-1-ol, 4,8,12-trimethyltridecanal, 4,8,12-trimethyltridecanoic acid, Z-3,7-dimethylocten-2-oic acid, Z-3,7,11-trimethyldodecen-2-oic acid, and 6,10,14-trimethylpentadecan-2-ol, were formally identified, and different pathways were proposed to explain the formation of such isoprenoid compounds.
本报告描述了一种从海洋沉积物中分离出的反硝化细菌(海杆菌属菌株CAB)对6,10,14-三甲基十五烷-2-酮的代谢情况。在有氧和反硝化条件下,该菌株能有效降解这种普遍存在的类异戊二烯酮。正式鉴定出了几种细菌代谢产物,4,8,12-三甲基十三烷-1-醇、4,8,12-三甲基十三烷醛、4,8,12-三甲基十三烷酸、Z-3,7-二甲基辛烯-2-酸、Z-3,7,11-三甲基十二碳烯-2-酸和6,10,14-三甲基十五烷-2-醇,并提出了不同的途径来解释此类类异戊二烯化合物的形成。
