Evidence for Bacterial Chemotaxis to Cyanobacteria from a Radioassay Technique

By N. Kangatharalingam, Lizhu Wang and John C. Priscu

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
