Effect of tryptophan catabolites on the development of heat resistance in Bacillus cereus spores
Ethyloxamate and nicotinamide inhibited the development of heat resistance and the biosynthesis of pyridine-2,6-dicarboxylic acid (dipicolinic acid) in Bacillus cereus spores. Addition of quinaldic acid or hydroxyanthranilic acid to an ethyloxamate-grown culture resulted in an increase in the number of heat resistant spores. Nicotinamide induced heat sensitivity could be reversed to different degrees by the addition of kynurenine or xanthurenic acid. Explanations which may account for these observations are presented.
