The colony-forming ability and the rate of reproduction of Bacillus stearothermophilus were determined as a function of temperature and pressure. Colonies were formed between 39 and 70 degrees C at atmospheric pressure and between 54 and 67 degrees C at 45 MPa. Colonies did not form at 55.9 MPa. The rate of reproduction in broth cultures decreased with increasing pressure at all temperatures. The rate of reproduction diminished rapidly with pressure above 10.4 MPa. Therefore, increased hydrostatic pressure was not sufficient to enable B. stearothermophilus to function beyond the temperature limiting growth and reproduction at atmospheric pressure, and B. stearothermophilus should grow in naturally or artificially warmed regions of the deep sea, where the pressure is less than approximately 50 MPa, although growth rates would be low above 10 MPa.
作为温度和压力的函数，测定了嗜热脂肪芽孢杆菌的集落形成能力和繁殖率。在大气压力下，菌落形成于 39 至 70°C 之间，在 45 MPa 下形成于 54 至 67°C 之间。在 55.9 MPa 下没有形成菌落。在所有温度下，在肉汤培养基中的繁殖率随压力的增加而降低。在压力超过 10.4 MPa 时，繁殖率迅速下降。因此，静水压力的增加不足以使嗜热脂肪芽孢杆菌在大气压力下限制生长和繁殖的温度之外发挥作用，并且嗜热脂肪芽孢杆菌应该在深海的自然或人为加热区域中生长，那里的压力小于约 50 MPa，尽管在 10 MPa 以上生长速度会很慢。
