Electron microscope grids were submerged in Lake Washington, Seattle, Wash., in June 1996 as bait to which Caulobacter sp. 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.
1996年6月，电子显微镜网格被沉入华盛顿州西雅图市的华盛顿湖，作为吸引柄杆菌属游动细胞附着并在其上原位繁殖的诱饵。对附着细胞柄部条带的计数表明，柄杆菌每天大约完成三个繁殖周期。出现了一系列形态类型的柄杆菌，还发生了一次食细菌者的捕食事件，这减缓了柄杆菌的积累并防止了种群老化。
