Hess, George E. (U. S. Army Chemical Corps, Fort Detrick, Maryland)and Milton Shon . Selection of thermostableSerratia marcescens from logarithmic-phase cultures as a means for inducing synchronous growth. J. Bacteriol.83: 781–784. 1962.—A relatively thermostable, apparently nonmultiplying, population ofSerratia marcescens was found in cultures in the exponential phase of growth. Thermal treatment of the whole culture resulted in the death of the multiplying cell fraction, although the nonmultiplying fraction remained viable. Subcultivation of the thermally treated suspensions yielded cultures in which most of the viable organisms multiplied synchronously for at least two generations.
