In this article we will discuss about the presence of pigments in photosynthetic bacteria. Because of the presence of carotenoids in all photosynthetic tissues their role is anticipated in photosynthesis. The tissue/cells rich in carotenoids devoid of chlorophyll do not photosynthesize. Light energy absorbed by carotenoids appears to be transferred to chlorophyll a or bacteriochlorophyll […]

In this article we will discuss about the mechanism of bacterial photosynthesis. The absorption of light is by a pigment molecule which after absorption delivers the energy to electron carriers that can transduce the energy into chemical form. The function of chlorophyll molecule is absorption of photons. The energy contained in the excited pigments is […]

In this article we will discuss about:- 1. History of Photosynthetic Bacteria 2. Classification of Photosynthetic Bacteria 3. Metabolism. History of Photosynthetic Bacteria: Before nineteenth century it was considered that the photosynthetic machinery is present in purple bacteria because these bacteria showed movement towards light (phototactic) and growth is also induced by light. On the […]
