Yeast Nitrogen Base Media

Saccharomyces Cerevisiae Yeast Nitrogen Base

Yeast Nitrogen Base media have been prepared according to the formulae of Wickerham (1943-51) and Burkholder (1943).  Their research on the nutritional requirements of yeast strains resulted in the formulation of Yeast Nitrogen Base (YNB).  YNB is a well defined composition of salts, vitamins, amino acids and a nitrogen source for a vigorous growth of Sacharomyces Cerevisiae.

Besides the original formulation of YNB, Formedium™ produces many variations of this medium without one or more components.  These YNB without ‘X’ media provide the researcher the possibility to grow yeast cells in the absence of a certain component or to replace a particular component.
