Summary

  1. (1)

    The increase in the resistance of speculating cells ofBacillus cereus to X-rays commences during the prespore phase, when the proteins of the sporangium are being enriched with cystine. The possibility that the cystine structure contributes to the radioresistance of the spores is discussed.

  2. (2)

    The relative increase in radio-resistance occurs before the synthesis of dipicolinic acid and the incorporation of45calcium, but continues to increase gradually in the course of further development.

  3. (3)

    The resistance of sporulating cells to higher temperatures develops progressively, according to the amount of dipicolinic acid synthesized.

  1. (1)

    Начало повышения устойчивости спорообразующих клеток Bacillus cereus к лучам Х относитя к периоду образования преспор, когда протеины спорангиев обогащаются цистином. — Обсуждается возможность участия цистиновой структуры в радиорезистентност и спор.

  2. (2)

    Относительное повышение радиорезистентност инаблюдается уже перед синтезомдипиколино вой кислоты и включением Са45, но в течение дальнейшего развития радиорезистентност ь продолжает постепенно повышаться.

  3. (3)

    Устойчивость спорообразующих клеток к повышенным температурам развивается постепенно в зависимости от количества синтезируемой дипиколиновой кислоты.
