Marine life asexually by binary fission, fragmentation, or budding; unlike bacteria and eukaryotes, no known species forms spores. Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle. Of eukaryotic groups, the protists are most commonly unicellular and microscopic. This is a highly diverse group of organisms that are not easy to classify. Several algae species are multicellular protists, and there are marine slime molds have
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
