“…Keeping out other phototrophic anoxygenic, Chloroflexus aurantiacus sprout effectively in environments with a moderate temperature of 50–60°C [ 4 , 5 ]. They can mostly acclimatize in various environmental circumstances, including wetlands, river water, hot springs, and sediments containing elevated-sulfide conditions [ 6 , 7 ]. Surprisingly, the species of bacteria have specific similar characteristics, particularly chimeric photosystem, with purple-photosynthetic bacteria (PPB) and green-sulfur bacteria (GSB) [ 8 , 9 ].…”
