Notes:
A toxigenic strain of Staphylococcus aureus known to produce both thermonuclease and enterotoxin was exposed to ultraviolet radiations. Thermonuclease deficient mutants were recovered on methylgreen-DNA-agar medium. All of twenty thermonuclease deficient mutants lost the capacity to produce coagulase, enterotoxin, and lecithinase. However, these functions were regained upon reversion with visible light (Photoreactivation) thus suggesting a coordinated control mechanism for the synthesis and release of the above metabolites. These characteristics in most of the mutants remained stable for 3 months.
