Abstract
Swarming cells of the sulfide-oxidizing bacterium Thiovulum majus form bands and show bioconvective patterns of swimming when placed in vessels containing H2S/O2 interfaces. Measurements of swimming velocities with video microscopic recordings under such conditions showed mean cell speeds as high as 615 microns s-1, unprecedented in bacteria.
摘要
硫化物氧化细菌大硫螺旋菌的游动细胞形成条带，当置于含有硫化氢/氧气界面的容器中时，会呈现生物对流的游动模式。在这种条件下，通过视频显微镜记录对游动速度进行测量，结果显示细胞平均速度高达615微米/秒，这在细菌中是前所未有的。
