Abstract
The major thrust area of microbial ecology is to understand the composition of microbial structure in the terrestrial environment because these communities affect biogeochemical cycles in an ecosystem. In this chapter, we analyze the soil microbial structure, the influence of microbial species and ecosystem processes in carbon storage, and control of greenhouse gas emission. We analyze the interactions of bacteria with plants and their metabolites. We then analyze the possible conditions for differences among types of microbes to influence C cycling and storage. The community structure involved in the generation of organic matter in detritus and in the rhizosphere. The microbial extracellular enzymes are one of the important factors that influence C cycling. Moreover, these ecosystem processes are very narrow and the specific niche plays a major role in biogeochemical cycles. In ecosystem processing a group of organisms is mostly involved in ecosystem functioning and responsible for the C cycle. In the soil C system broad processes are responsible for C storage and decomposition. In this chapter, therefore, we will focus on the role of microbes associated with C storage and decomposition.
