This review highlights the significant advances which have been made in prokaryotic ecology and biotechnology due to the application of metagenomic techniques. It is now possible to link processes to specific microorganisms in the environment, such as the detection of a new phototrophic process in marine bacteria, and to characterise the metabolic cooperation which takes place in mixed species biofilms. The range of prokaryote derived products available for biotechnology applications is increasing rapidly. The knowledge gained from analysis of biosynthetic pathways provides valuable information about enzymology and allows engineering of biocatalysts for specific processes. The expansion of metagenomic techniques to include alternative heterologous hosts for gene expression and the development of sophisticated assays which enable screening of thousands of clones offers the possibility to find out even more valuable information about the prokaryotic world.
