The growth rate of Chlorella sorokiniana decreased in a linear fashion as the partial pressure of oxygen was increased from 711 to 1,478 mm of Hg. Under two atmospheres of oxygen pressure, growth ceased after 10 to 12 hr. This cessation of growth was not due to any permanent injury, as growth resumed when oxygen partial pressure was reduced to ambient levels. The inhibition occurred under both autotrophic and heterotrophic growth conditions and was not accompanied by an increase in cell size. The results indicated that the tolerance of Chlorella cells to elevated oxygen pressures was not an absolute immunity, and that inhibition of growth at very high oxygen pressures cannot be accounted for by an inhibition of photosynthesis alone.
随着氧分压从711毫米汞柱增加到1478毫米汞柱，索氏小球藻的生长速率呈线性下降。在两个大气压的氧气压力下，生长在10至12小时后停止。这种生长停止并非由于任何永久性损伤，因为当氧分压降至环境水平时生长会恢复。这种抑制在自养和异养生长条件下均会发生，且不会伴随着细胞大小的增加。结果表明，小球藻细胞对升高的氧气压力的耐受性并非绝对免疫，并且在非常高的氧气压力下生长的抑制不能仅由光合作用的抑制来解释。
