What Is Culture Collection Centres?
Culture collections are centres that provide authentic examples of organisms, often microorganisms or animal and/or plant cell cultures that can be grown or maintained in the laboratory. They normally have a public service role and often provide other biological resources and services.
Which is the largest culture collection Centre in the world?
ATCC
Established in 1925 to serve as a national center for depositing and distributing microbiological specimens, ATCC has since grown to distribute in over 150 countries. It is now the largest general culture collection in the world.
Which is the best known culture collection Centre in the world?
The World Data Center for Microorganisms (WDCM), launched in 1966, is the data center of WFCC and Microbial Resources Centers network (MIRCEN). WDCM is the global registry for culture collections and serves as an information resource for the user community.
What is the purpose of a stock culture?
A culture of a microorganism maintained solely for the purpose of keeping the microorganism in a viable condition by subculture, as necessary, into fresh medium.
How are culture collection Centres useful?
Culture collections play a vital role in the conservation and sustainable use of microbial resources [2]. They also provide the authentic biological material for high quality research and teaching [3] in the form of reference strains, reagents for quality control, etc. This role is thus played by a culture collection.
What are the two main types of culture?
The two basic types of culture are material culture, physical things produced by a society, and nonmaterial culture, intangible things produced by a society.
How many cultures are collected in India?

How do you create a stock culture?
Inoculate a culture flask containing 5-10 ml of liquid medium with a single bacterial colony and grow the culture overnight. 2. Transfer 3.4 ml of the overnight culture to a sterile vial containing 0.6 ml of sterile glycerol. Place the cap on the vial and mix the contents thoroughly by vortexing.
How do you maintain stock cultures?
Preserving Stock Cultures A popular method for preserving microorganisms is through lyophilization, or freeze drying. This method is best for long term storage. The lyophilization process requires costly equipment including a lyophilizer, vacuum pump, generator, etc.
What Is Culture Collection in microbiology?
Microbial culture collections focus on the acquisition, authentication, production, preservation, catalogueing and distribution of viable cultures of standard reference microorganisms, cell lines and other materials for research in microbial systematics. Culture collection are also repositories of type strains.
Why do you need a good stock culture collection?
There are a number of reasons why a microbiology laboratory needs stock cultures in good condition. The typical stock culture collection may contain isolates that fall into one or more of the following categories: Reference strains for quality control of culture media and methods
Why do we need a culture collection center?
Therefore, such important cultures must be deposited at National or International Culture Collection Centres. At these centres the cultures are properly maintained by the experts. These cultures are governed by stringent rules and regulations so that intellectual property rights of the depositors must be protected.
How is stock culture maintained in a laboratory?
Whatever the size of the laboratory ’s stock culture collection, it is important that it is properly maintained. Traditionally this has been a matter of culturing isolates on agar slants of suitable media and then subculturing onto fresh slants at regular intervals.
Who is the American type culture collection ( ATCC )?
The American Type Culture Collection (ATCC) is a private, nonprofit organization dedicated to the acquisition, preservation, authentication, and distribution—the “APAD” activities—of diverse biological materials. ATCC was founded by scientists in 1925 to serve as a national repository and distribution center for cultures of microorganisms.
