ans....if u know don't spam.......

Answer 1

Anoxygenic phototrophic bacteria were discovered at the dawn of microbiology more than 100 years ago. The first anoxygenic phototrophic bacterium was identified in 1901 and was subsequently described as Rhodospirillum species by the German botanist, Hans Molisch in 1907 (10). Rhodospirillum species are purple bacteria that belong to the phylum Proteobacteria, and the term “purple bacteria”, which refers to a major group among anoxygenic phototrophic bacteria, was also simultaneously proposed by Molisch. Another major anoxygenic phototrophic group, green sulfur bacteria, which belong to the phylum Chlorobi, was described by the Russian biologist, Georgii A. Nadson in 1906 (13). Martinus W. Beijerinck, a famous microbiologist in the Netherlands, who was a contemporary of Molisch and Nadson, proposed a lactic acid bacterial group, the genus Lactobacillus, in 1901.
