The urgency of the subject Microorganisms as well as bacteria in particular have demonstrated significant practical meaning to humans by their application in medical agriculture industry and environmental treatment. To find a large amount of new microbial genes and apply them in life the study of the genomic diversity of microbial communities becomes an important issue that considerably gains many interests from biologists. However some recent discoveries show that the vast majority of microbial species approximately 99 have been uncultured. Therefore the use of common culturing techniques is unable to collect the entire genetic resources of all microbiota. Presently by using metagenomics - an effective tool to sequence the whole genome of all organisms obtained directly from an environmental sample genes of both cultured and uncultured microorganisms are fully studied and analyzed. In Vietnam the development of agriculture with large-scale and concentrated production generates a large amount of wastes and byproducts which are commonly discarded by
