Toxin production Properties Mobile elements ensure that genes can be spread to nontoxigenic derivatives or be lost from cell Experimentally called"curing"get nontoxigenic derivatives Phase of production Some produced continuously by growing bacteria Other synthesized when cells enter stationary phase(true also for many antibiotics) BIOL 533 Lecture 9BIOL 533 9 Lecture 9 Toxin Production – Properties • Mobile elements ensure that genes can be spread to nontoxigenic derivatives or be lost from cell – Experimentally called “curing”—get nontoxigenic derivatives – Phase of production • Some produced continuously by growing bacteria • Other synthesized when cells enter stationary phase (true also for many antibiotics)
