Potential of Microorganisms in Clean-up the Environment
Pages : 271-285Download PDF
Microorganisms are ubiquitous in nature and make up the biodiversity on earth. They perform several important processes in cycling of nutrients, degradation of various compounds globally. Knowledge of microbial activities helps mankind to find various strategies to utilize agricultural natural resources in long term sustainable manner. In sustainable agriculture bacteria and fungi are being utilized as biofertilizers. Plant growth promoting rhizobacteria (PGPR) play important role in soil fertility. Use of PGPR as biofertilizers should be increased to stop deterioration of soil fertility due to extensive application of chemical fertilizers. Change in living standards contributes increased dependence on chemicals in day today life, These chemicals are used from our soaps, detergents, disinfectants, insecticides, like DDT, pollute receiving water bodies through sewage. Various microorganisms can be used for bioremediation of such waste water containing recalcitrant and xenobiotic compounds. The microbial activities that help us to design an excellent new strategy of life leading to sustainable future are presented.
