Biosensor it affects marine organisms, especially plankton (floating microorganisms) and viruses that attack plankton. Plankton form the base of the marine food chains and are believed to affect our planet's temperature and weather by uptake of CO for photosynthesis. Deneb Karentz, a researcher at the Laboratory of Radio-biology and Environmental Health (University of California, San Francisco) has devised a simple method for measuring ultraviolet penetration and intensity. Working in the Antarctic Ocean, she submerged to various depths thin plastic bags containing special strains of "E. coli" that are almost totally unable to repair ultraviolet radiation damage to their DNA.

National Collection of Industrial Food and Marine Bacteria National Collection of Industrial Food and Marine Bacteria The National Collection of Industrial, Food and Marine Bacteria (NCIMB) is a culture collection in the United Kingdom consisting of microorganisms from environmental samples (particularly marine bacteria) as well as bacteria involved in the production or spoilage of food and drink, and bacteria with important industrial properties. It is a large reference collection and has over 10,000 deposits. Deposits to the collection can be made for research purposes (for example to name a new species), or for inclusion into patent submissions. Prior to 1982 the collection was one of a number of
