Fentachlorophenol is readily degraded in biofilm reactors, so bioremedi-ation is a promising option for the treatmenl of contaminated groundwater brought to the surface as part of a pnmp-and-treat operation.

The proteome of soil microbiota has been elucidated recently using 2D gel and spectrometry at the University of California. These investigators have examined the community of soil microorganisms in a biofilm from a mine. They have identified about 1200 proteins one important protein identified among them is a novel cytochrome that is responsible for the oxidation of iron and for the formation of the biofilm itself. The metapro-teomics of microbial communities involved in the bioremediation of soil and water, particularly those in ground and estuaries, are difficult.

Extra cellular polymeric substances (EPS) produced by microorganisms are a complex mixture of biopolymers primarily consisting of polysaccharides, as well as proteins, nucleic acids, lipids, and humic substances. EPS make up the intercellular space of microbial aggregates and form the structure and architecture of the biofilm matrix. The key functions of EPS are comprised of the mediation of the initial attachment of cells to different substrate, and protection against environmental stress and dehydration. The latter has a profound impact on an array of biomedical, biotechnical, and industrial fields including pharmaceutical and surgical applications, food engineering, bioremediation.

Biofilm-mediated bioremediation resulted more efficient and safer bioremediation in comparison vith that, for example, carried out by planktonic bacteria. Microorganisms presenting in the biofilm possessed a concrete opportunity to adapt to different environments and to ensure the microbial survival allowing the mineralization processes.
