Abstract
We examined the role of bacteriochlorophyll synthesis on the regulation of carotenoid synthesis in Rhodopseudomonas capsulata. Strains capable of making bacteriochlorophyll accumulated greater amounts of carotenoids under low oxygen than they did under high oxygen. However, strains unable to produce bacteriochlorophyll did not regulate their carotenoid production in response to changes in oxygen tension. This indicates that oxygen does not directly regulate carotenoid production.
摘要
我们研究了细菌叶绿素合成在荚膜红假单胞菌中对类胡萝卜素合成调控的作用。能够合成细菌叶绿素的菌株在低氧条件下积累的类胡萝卜素比在高氧条件下更多。然而，无法产生细菌叶绿素的菌株不会根据氧张力的变化来调节其类胡萝卜素的产生。这表明氧不会直接调控类胡萝卜素的产生。
