The absolute requirement of deposition of type strains of new taxa in one or more of the internationally recognized permanent culture collections, in conjunction with description and valid publication, is a recommendation under Rule 30 of the Bacteriological Code (International Committee of Systematic Bacteriology, 1997).

Under this rule, a taxon cannot be considered validly published and hence a valid name unless it has been deposited and it is available for distribution from a recognized culture collection. Moreover, descriptions of new taxa are not accepted for publication in the International Journal of Systematic and Evolutionary Microbiology, the official organ of the International Committee on Systematic Bacteriology, unless type strains have been deposited.
