Abstract

During O2-free growth in the light and in medium with pyruvate, Rhodospirillum rubrum exhibits diauxic growth. The cells first fermented pyruvate and afterwards photometabolized. Exogenous cyclic AMP acted to prolong the lag period between fermentative and photosynthetic development, as well as to slow the light-dependent growth rate. This observation, and in situ changes in the cyclic AMP levels in cells undergoing biphasic growth, suggested that the cyclic nucleotide was involved in photosynthetic differentiation, perhaps by repressing the formation of the bacteriochlorophyll needed to support growth in the light.

摘要

在光照且含有丙酮酸的无氧培养基中生长时,深红红螺菌呈现双相生长。细胞首先发酵丙酮酸,然后进行光代谢。外源性环磷酸腺苷(cAMP)的作用是延长发酵与光合发育之间的延迟期,同时减缓光依赖生长速率。这一观察结果,以及双相生长细胞中环磷酸腺苷水平的原位变化,表明环核苷酸参与了光合分化,可能是通过抑制支持光照下生长所需的细菌叶绿素的形成来实现的。
