The goal of this study was to compare the environmental factors that determine viability of the gram-negative photosynthesizing bacteria Rhodobacter capsulatus (specifically, light and growth medium composition) and to assess the effect of these factors on the synthesis and composition of lipopolysaccharides released from the cell wall. Depletion of medium resulted in the release of lipopolysaccharides with a truncated polysaccharide fragment. It is concluded that, due to high viability of these bacteria, the main factor that induced lipopolysaccharide release from the cell wall, irrespective of culturing conditions, is cell division rather than cell death.
本研究的目的是比较决定革兰氏阴性光合细菌荚膜红细菌生存能力的环境因素（具体为光照和生长培养基成分），并评估这些因素对从细胞壁释放的脂多糖的合成和组成的影响。培养基耗尽导致具有截短多糖片段的脂多糖释放。得出的结论是，由于这些细菌的高生存能力，无论培养条件如何，诱导脂多糖从细胞壁释放的主要因素是细胞分裂而非细胞死亡。
