A survey of 30 representative strains of human gram-positive intestinal bacteria indicated that Roseburia species were among the most active in metabolizing linoleic acid (cis-9,cis-12-18:2). Different Roseburia spp. formed either vaccenic acid (trans-11-18:1) or a 10-hydroxy-18:1; these compounds are precursors of the health-promoting conjugated linoleic acid cis-9,trans-11-18:2 in human tissues and the intestine, respectively.
一项对30种具有代表性的人类革兰氏阳性肠道细菌菌株的调查表明,罗斯氏菌属是代谢亚油酸(顺式-9,顺式-12-18:2)最活跃的菌属之一。不同的罗斯氏菌属菌株分别形成了反式-11-十八碳烯酸(反式-11-18:1)或10-羟基-18:1;这些化合物分别是人体组织和肠道中具有健康促进作用的共轭亚油酸顺式-9,反式-11-18:2的前体。
