Reference Strains

There thousands of reference strains in the National Collection of Industrial, Food and Marine Bacteria. The strains are a valuable reference for identification, and have a wide range of potential research and industrial applications.

Potential uses within the food, drink and supplements sectors include:

  • Food production strains and started cultures
  • Production of probiotic products
  • Bioremediation
  • Use in quality control procedures

For example, the collection includes an extensive selection of lactic acid bacteria , which have been isolated from a diverse range of sources including naturally fermented pickles and yoghurt, marinated fish, brewery yeast, fermented cassava and lettuce leaves.

NCIMB reference strains are supplied under the terms of our Material Transfer Agreement (MTA), which allows scientists greater flexibility in their responsible use. You can download our MTA via the link on the right hand side of this page.

You can contact us to enquire about availability of specific strains, or search the NCIMB catalogue on this website.

The catalogue gives details of the colony and cellular morphology you can expect from the strain as well as information on growth requirements, metabolite production, the environment from which the strain was isolated, equivalency and references, where available.

Bacteria

Most bacterial cultures are supplied freeze-dried in sealed glass ampoules, but they can also be supplied as an active culture if required.

Bacteriophages and plasmids

Bacteriophages and plasmids are supplied as thawed liquid suspensions in plastic vials.

Media Recipes

We maintain a searchable database of media recipes, which includes media recipes for all the strains in our collection. The media recipe search can be accessed via the link on this page.

Please note:

All cultures supplied by NCIMB are, to the best of our knowledge, free of background IP or ownership issues which prevent or restrict scientific research associated with those cultures. Should there be any pre-conditions attached to the release or use of an NCIMB culture outside those already stipulated in our standard Material Transfer Agreement (MTA), we will inform the purchaser in advance.

It is ultimately the responsibility of the end user to ensure that any development, commercial exploitation or use of cultures supplied does not infringe patent or other IP or ownership rights already granted, or have any obligations with regard to the country of origin as laid down in the Convention on Biological Diversity (CBD).

For more information about NCIMB's CBD policy, please see our CBD information sheet.

Explanatory note on equivalency

There is some overlap in strain holdings between major culture collections, where the same strain has been deposited in multiple collections. Culture collections share this information where it is known, and most publish a list of "equivalents".

No culture collection can absolutely guarantee strain equivalency as errors occasionally happen and in a very few cases genetic drift may alter the properties of the strain between collections. However these are rare occurrences, and it is generally accepted that, for example, when a collection states that Pseudomonas aeruginosa NCIMB 8295 = NCTC 10332 = DSM 50071 = CECT 110 = CIP 63.52 these cultures will be indistinguishable from one another.

Please note that claims of "equivalency" by NCIMB do not make any claim upon the handling rights or ownership of that strain. Each culture collection has its own conditions of supply and/or MTA which may place restrictions or undertakings when using that strain. All culture collection users should take care to read those conditions when purchasing any organism from a culture collection.
