1.1 Introduction
Metagenomics, or also known as environmental genomics, is study of collective genomes of microorganisms. By using metagenomics, we are able to perform genomic analysis of microorganisms by direct extraction and cloning of DNA from an assemblage of microorganisms, collected from various types of environment such as soil, river, feces and marine (Handelsman, 2004; Bhuiyan et al., 2011). The recent development of molecular biology designed to access this wealth of genetic information through environmental nucleic acid extraction has provided a means of avoiding the limitations of culture-dependent genetic exploitation (Cowan et al., 2005).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitations of the Study and Definition of technical terms.
