green nonsulfur bacteria การใช้

The first bacterial descendant, which split off from the Last Universal Ancestor, was defined by a strong sacculus, and later descendants branched off in the following order : low G + C Gram-positive bacteria, high G + C Gram-positive bacteria, Clostridia-Fusobacteria, Thermotaga, Deinococcus-Thermus-Green nonsulfur Bacteria, Cyanobacteria, Spirochetes, Chlamydia-Cytophaga-Bacteriodes, Green sulfur bacteria, Aquifex, and the Proteobacteria ( epsilon, delta, alpha, beta, gamma ) . ( Gupta, 2004 ) The predecessor of the proteobacteria probably gained its energy through anaerobic photosynthesis, and was contingent on a reductant, carbon and convenient oxygen levels.
