A SYNTHETIC MEDIUM FOR EXTREMELY HALOPHILIC BACTERIA

Abstract
A synthetic medium, made up of 15 amino acids, adenylic and uridylic acid, glycerol, asparagine or ammonium chloride, and various salts, has been developed for halophilic bacteria. Halobacterium cutirubrum and Sarcina litoralis grew as well in this medium as in a complex medium containing casein hydrolysate and yeast extract. Growth of Halobacterium halobium, Halobacterium salinarium, and Sarcina morrhuae was slower in the synthetic medium and the final cell densities were not as great as in the complex medium.
