| Research Abstract |
Purple photosynthetic bacteria were able to survive under the conditions of very low organic nutrients by using light energy in examined 4 species. In the microbial community of hot springs, in which low concentrations of electrons are provided from the water, the biomass grows with continuous cycling of the electrons in the community with the help of photosynthetic bacteria. In the cycling, hydrogen production and consumption play important roles. In the oligotrophic lakes and ponds, partially denitrifying photosynthetic bacteria were involved in the denitrification with non-photosynthetic bacteria.
