Production of Staphylocoagulase in a Chemically Defined Medium

Abstract

IN the course of work on the purification of staphylocoagulase, a possible approach appeared to be the production of the enzyme in a protein-free ‘synthetic’ medium. While growth of Staphylococcus aureus occurs according to Fildes et al.1, Gladstone2 and Gale3 in media simpler than that reported here, for our purpose, which is concerned exclusively with the production of coagulase, a medium containing a wide range of amino-acids and vitamins seemed advisable. This medium has yielded good growth of a number of freshly isolated strains of coagulase-positive staphylococci, without prior ‘training’.
