TCA Cycle Replenishing Pathways in Photosynthetic Purple Non-Sulfur Bacteria Growing with Acetate

TCA Cycle Replenishing Pathways in Photosynthetic Purple Non-Sulfur Bacteria Growing with Acetate

Purple non-sulfur bacteria (PNSB) are anoxygenic photosynthetic bacteria harnessing simple organic acids as electron donors. PNSB produce <i>a</i>-aminolevulinic acid, polyhydroxyalcanoates, bacteriochlorophylls <i>a</i> and <i>b</i>, ubiquinones, and other valuab...

They are highly promising producers of molecular hydrogen. PNSB can be cultivated in organic waste waters, such as wastes after fermentation. In most cases, wastes mainly contain acetic acid. Therefore, understanding the anaplerotic pathways in PNSB is crucial for their potential application as producers of biofuels. The present review addresses the recent data on presence and diversity of anaplerotic pathways in PNSB and describes different classifications of these pathways.https://www.mdpi.com/2075-1729/11/7/711purple non-sulfur bacteriatricarboxylic acid cycleanaplerotic pathwaysglyoxylate pathwayethylmalonyl-CoA pathwaycitramalate cycle
