Microorganisms are of critical importance to the sustainability of life in our planet. The untapped diversity of microorganisms is a resource for new genes and organisms of value to biotechnology. The diversity patterns of microorganisms can be used for monitoring and predicting environmental change. Water sediments and leaf litter samples were collected from streams of Silver falls, Pillar rock, Vattakanal, Villpatti and Gundar. In this present study the role of different microbial groups as decomposers in the littoral area and their metabolic and structural responses of sediment microbial communities to the addition of different carbon substances have been assessed. Leaf litter and sediments in five selected streams displayed many microorganisms of bacteria and fungi. However, if the pollution continues at this level the five streams under study will soon reach bad conditions and problems arise to microbial population. Thus the sustenance of environment especially in streams requires a thoughtful management of microorganisms.
