In cells of Rhodopseudomonas capsulata, grown at growth limiting light intensity (7 W x m-2), the cellular bacteriochlorophyll (Bchl) content increased 13-fold, the Bchl concentration of membranes 3.4 fold, the concentration of reaction centers in membranes 1.6-fold, the size of the photosynthetic unit twofold, the concentration of carotenoids in membranes 2.4 fold and the number of intracytoplasmic membrane vesicles, bearing the photosynthetic apparatus, 6..3 fold in comparison with cells grown at 2000 W x m-2 light intensity. Thus, the variation of incident caused mainly a variation of the amount of intracytoplasmic membrane vesicles per cell, but also a variation of the size and concentration of photosynthetic units in the membrane system.
在以生长限制光强（7 W·m⁻²）培养的荚膜红假单胞菌细胞中，与在2000 W·m⁻²光强下培养的细胞相比，细胞细菌叶绿素（Bchl）含量增加了13倍，膜中Bchl浓度增加了3.4倍，膜中反应中心浓度增加了1.6倍，光合单位大小增加了两倍，膜中类胡萝卜素浓度增加了2.4倍，承载光合装置的胞内膜泡数量增加了6.3倍。因此，入射光强的变化主要引起每个细胞中胞内膜泡数量的变化，也引起膜系统中光合单位大小和浓度的变化。
