Pigments in Photosynthetic Bacteria | Microbiology

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 a and utilized in the [...]

Photosynthetic Bacteria: History and Classification | Microbiology

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 other hand, S. Winogradsky, a [...]
