This 1988 volume brought together for the first time a wealth of information for those using yeasts in biotechnology. The volume is a guide to the preservation and identification of yeasts and their deposit for patent purposes; it describes the data centres and culture collection organisations from which information and expert help was obtained. The international panel of authors combined with the microbial resource centres themselves provide a unique source book. The volume will continue to be of interest to microbiologists, fermentation scientists and others who use yeasts.
