Abstract
Lyngbya birgei and Aphanizomenon flos-aquae elicited a significant chemotactic attraction of Aeromonas hydrophila compared with controls lacking cyanobacteria. There was a positive exponential relationship between biomass (chlorophyll a) of L. birgei and A. flos-aquae and chemotactic attraction of A. hydrophila. The assay equipment was simple and reliable and could be used to study bacterial chemotaxis in other species in situ.
摘要
与缺乏蓝藻的对照相比，藻青菌和水华鱼腥藻能显著吸引嗜水气单胞菌向其趋化。藻青菌和水华鱼腥藻的生物量（叶绿素 a）与嗜水气单胞菌的趋化性吸引力之间存在正指数关系。该检测设备简单可靠，可用于原位研究其他种类细菌的趋化性。
