Amino acid requirements for the growth and production of some exocellular products of Staphylococcus aureus.

A simple, defined synthetic medium has been developed for the growth of a toxic-shock-syndrome-associated Staphylococcus aureus strain (FRI 1187) in continuous culture, which gives a high growth yield and assayable amounts of acid phosphatase, haemolytic activity, hyaluronate lyase and toxic-shock-syndrome toxin-1. It consists of multiple ions, ammonium sulphate, glucose, cystine, aspartate, glutamate, arginine, glycine, proline, nicotinic acid and thiamine.
