Vaccenic acid (11-18:1) accounted for 92% of the fatty acids in the extractable lipids of log-phase Nitrobacter and Hyphomicrobium. During the stationary phase, both genera formed a 19-carbon cyclopropane fatty acid which increased in proportion to a decrease in the amount of vaccenic acid.
vaccenic酸（11-18:1）占对数期硝化细菌和生丝微菌可提取脂质中脂肪酸的92%。在稳定期，这两个属都形成了一种19碳环丙烷脂肪酸，其比例随着vaccenic酸含量的减少而增加。
