Induction of H. lacusprofundi β-galactosidase in Halobacterium sp. NRC-1 (pMC2). Enzyme assays were done at 25°C after incubating cells for 72 hours at various temperatures for cell lysate (blue, ◊) and supernatant (red, □). Activity levels are shown in Miller units (MU) on the left for cell lysate and the right for supernatant, and are the average of triplicate experiments, with standard deviation shown with error bars.
