Biotech is effectively changing the way the largest chemical companies do business, in which as demonstrated by pharmaceutical industries, DNA is used to create novel therapeutics. A crucial advance in this direction is coming from Metagenomics, the emerging science branch that has the potential to substantially impact industrial production, as shown by the company founded by Venter http://www.tigr.org/. Industries have different motivations to probe the enormous resource represented by uncultivated microbial diversity. Currently, there is a global political drive to promote biotechnologies as a central feature of the sustainable economic future of modern industrialized societies. This requires the development of novel enzymes, processes, products and applications. Metagenomics is the branch of science that integrates biology and technology. Based on the genomic analysis of DNA, it has the power to solve problems in many different fields, from positively impacting human health to enabling a better understanding of the environment and agricultural systems as well as creating new biological sources of energy.
