光合细菌是能进行光合作用的一类细菌。光合作用是地球上最重要,规模最大的生物化学过程。通过这一过程,光合生物把太阳能转化成细胞合成所必需的化学能。十九世纪中期就有学者对这一类细菌进行无光合成作用研 Photosynthetic bacteria are photosynthetic bacteria. Photosynthesis is the most important and largest biochemical process on Earth. Through this process, photosynthetic organisms convert solar energy into the chemical energy necessary for cell synthesis. In the mid-nineteenth century, some scholars did not study the role of this type of bacteria in the synthesis of light
