INFLUENCE OF CYSTEINE ON THE PRODUCTION OF HAEMOTOXIN OF CL. WELCHII
Keyword(s):
It has been shown that the addition of 0.1% or more of cysteine to Robertson's chopped meat media completely inhibits the production of haemotoxin by Cl. welchii and that H2S has a similar effect. The effect is shown to be related to the metabolism of the organisms and not to a direct reaction with the formed toxin. The addition of these concentrations of cysteine was shown to have little effect upon the oxidation-reduction potential of sterile media but a marked effect upon the oxidation-reduction potential of cultures during the most active growth period. Beef muscle media low in cystine were shown to give a good yield and fish muscle relatively high in cystine was shown to give a poor yield of haemotoxin.
