Abstract
Propionate catabolism was monitored in anaerobic cocultures of propionate-degrading and methanogenic bacteria. Metabolism was monitored by use of C-enriched propionate and succinate. The intermediates identified indicated that the methylmalonyl coenzyme A pathway was used in these cultures. The data also indicated that a transcarboxylation reaction between succinate and propionyl coenzyme A occurred, yielding propionate and methylmalonyl coenzyme A.
摘要
丙酸的分解代谢在产丙酸降解菌和产甲烷菌的厌氧共培养物中进行了监测。通过使用 C 标记的丙酸和琥珀酸进行代谢监测。鉴定出的中间产物表明，该途径在这些培养物中被使用。数据还表明，琥珀酸和丙酰辅酶 A 之间发生了转羧基反应，生成丙酸和甲基丙二酰辅酶 A。
