Abstract
SUMMARY: Growth of Bacillus subtilis and of Escherichia coli following treatment with oxygen at 10 atmospheres for 18 hr was synchronous. Treatment at lower pressures resulted in a much lower degree of synchrony. After exposure to high-pressure oxygen to induce synchronous growth of B. subtilis the resistance of various stages of the cell cycle to further treatment with oxygen at 10 atm. was studied. Maximum resistance occurred immediately following division of the bacilli and then fell to a low value. The region of maximum resistance in B. subtilis compared fairly closely with the time of maximum catalase activity.
