1996年6月，在华盛顿州西雅图的华盛顿湖浸泡了电子显微镜栅格，作为诱饵，Caulbactersp.蜂群会附着在上面，然后它们会在原地繁殖。对附着细胞柄中条带的计数表明，该菌每天大约完成三个繁殖周期。出现了一系列杆状杆菌的形态类型，以及一段细菌体放牧的插曲，减缓了杆状杆菌的积累，防止了种群的老龄化。
ABSTRACT Electron microscope grids were submerged in Lake Washington, Seattle, Wash., in June 1996 as bait to which Caulobactersp. swarmers would attach and on which they would then reproduce in situ. Enumeration of bands in the stalks of attached cells implied that the caulobacters were completing approximately three reproductive cycles per day. A succession of morphological types of caulobacters occurred, as well as an episode of bacteriovore grazing that slowed the accumulation of caulobacters and prevented the aging of the population.
