Abstract

DNA and protein precursors were incorporated into trichloroacetic acid-precipitated material by bacterial cell suspensions during incubation for 50 to 100 days at -15 degrees C. Incorporation did not occur at -70 degrees C and was inhibited by antibiotics. The results demonstrate that bacteria can perform macromolecular synthesis under conditions that mimic entrapment in glacial ice.

摘要

在-15℃下孵育50至100天期间，细菌细胞悬液将DNA和蛋白质前体掺入三氯乙酸沉淀的物质中。在-70℃下不发生掺入，且掺入受到抗生素的抑制。结果表明，细菌能够在模拟被困于冰川冰中的条件下进行大分子合成。
