✦ Synopsis


A simple rapid method for preparing synchronous cultures of Bacillus subtilis has been used to investigate changes in density during the cell cycle. Asynchronous cells separated on a stepped Percoll density gradient had a mean cell density of 1.117 g ml-1 +/- 0.004. Samples from a synchronous culture exhibited variation (ca. 1.5%) in mean cell density which was greatest at the onset of cell division. An asynchronous control culture showed little variation in density. These results are discussed in relation to previous work on Escherichia coli.

The sporulation potential of Bacillus subtilis as a function of position in the cell cycle was determined by transferring cells from growth medium to sporulation medium at various times during growth. Growth was induced by incubating heat-activated spores in rich medium or by diluting stationary pha
