Abstract

Algae and bacterial organisms have the co-existed ever since the early stages of an evolution. This co-evolution has the revolutionized life on the earth planet system in many aspects. Algae and bacteria are both together influence the ecosystems as varied by as deep seas to the lichens and represent it is all conceivable modes of an interactions- from the mutualism to parasitism. After several studies have shown that algae and bacterial organisms synergistically affect each other's physiology and metabolism actions, a classic case being algae-proteobacteria interaction occurs in parasitic actions. These interactions are made from ubiquitous, and they define the primary productivity in most of the ecosystems.
