A time-lapse capillary assay to study aerotaxis in the archaeon Halobacterium salinarum

We have developed a method for time-lapse video photography and line scanning of optical densities for analysis of aerotactic responses of Halobacterium salinarum. This automated digital technique, along with line scan analysis of selected frames, gives a unique profile of the aerotactic migration of halobacterial cells. [Copyright &y& Elsevier]
