From the time life was created on Earth, photosynthetic bacteria evolved along with changes in the environment. Photosynthetic bacteria are one type of bacteria that sustains good ecosystems with other useful bacteria (such as actinomycetes) as a leading player in the cycle of N, CO2, S, and others on Earth. Though the true name of Photosynthetic Bacteria (P.S.B.) is Phototrophic Bacteria (P.T.B.), they are so called as they possess photosynthetic pigment. We are culturing and selling the environmentally friendly biomaterials to bring out the excellent nature of P.S.B.
