Modern biotechnology has a steadily increasing demand for vitamins, antibiotics and, in particular, novel biocatalysts for use in the production of flavors, agrochemicals, pharmaceuticals and high-value fine chemicals. Novel experimental approaches are being developed in attempts to identify such molecules. However, it is known that up to 99.8% of the microbes present in many environments are not readily culturable; hence, they cannot be exploited for biotechnology. The 'metagenome technology' offers a solution to this problem by developing culture-independent methods to isolate, clone and express environmental DNA. So far, metagenome-based approaches have led to the isolation of many novel biocatalysts and a variety of other molecules with a high potential for downstream applications.
