THE EFFECT OF SALT CONCENTRATION ON THE BIOCHEMICAL REACTIONS OF SOME HALOPHILIC BACTERIA

Abstract

Tests with a number of strains of halophilic bacteria indicate that biochemical reactions, such as protein hydrolysis, and indol and hydrogen sulphide production, may vary with the concentration of salt in the medium. It is suggested therefore that, in reporting the biochemical reactions of halophilic bacteria, the concentration of salt in the medium be definitely stated, and that before negative results are reported, the tests be made at different salt concentrations over the range at which the organism grows.
