Purple and Green(Anoxygenic Phototrophic) Bacteria Classification Anoxygenic phototrophic bacteria are classified based on their bacteriochlorophylls and photosynthetic membrane systems into three major groups Purple Bacteria(Nonsulfur purple, Purple sulfur bacteria) Green Bacteria(Green sulfur, green nonsulfur bacteria) Heliobacteria Anoxygenic phototrophic bacteria also produce carotenoid pigments. Therefore, the colors of the bacteria are the combination of bacterio chlorophylls and carotenoid pigments
