Abstract

In situ growth of Sphaerotilus on microscope slides immersed in a thermally polluted stream was studied. Ultraviolet radiation was used to differentiate between passive attachment of organisms from the water and growth of the organisms on the slides. Colonization of the slides in this environment took place solely by means of swarmer cells. A generation time of 2.3 hr was obtained at a water temperature of 18-22 C.

摘要

研究了浸没在热污染溪流中的载玻片上球衣菌的原位生长情况。利用紫外线来区分水中生物体的被动附着与载玻片上生物体的生长。在这种环境下,载玻片上的定殖仅通过游动细胞进行。在水温18 - 22摄氏度时,获得的世代时间为2.3小时。
