噬菌体广泛分布于自然界，可能是调节其寄主种群的重要因素。研究了单菌种和温带寄生噬菌体的模型连续培养系统。溶原性大肠杆菌159T−(λCTS的稳态培养产生少量游离λCTS噬菌体。温度对这种培养物造成冲击，导致噬菌体浓度急剧增加，细胞数量随之下降。随着时间的推移，系统恢复到稳定状态。
Bacteriophages are widely distributed in nature and may be important factors in regulating populations of their hosts. Model continuous culture systems of a single bacterial species and a temperate parasitic phage have been studied. Steady state cultures of lysogenicEscherichia coli159T−(λcts) produced a small quantity of free λ cts phage. Temperature shocking such a culture resulted in a sharp increase in phage concentration with a concomitant fall in cell population. With time the system returned to a steady state condition.
