When Escherichia coli was incubated at the growth-refractory temperatures of 48 and 54 degrees C, expression of the cel operon was demonstrated by phospho-beta-glucosidase activity. This enzyme activity was also detected at the growth-refractory temperatures in Salmonella typhimurium and Pseudomonas aeruginosa. Thermotolerant and mesothermophilic mutants of E. coli, S. typhimurium, and P. aeruginosa, able to grow with generation times of 30 to 40 min at 48 and 54 degrees C, exhibited phospho-beta-glucosidase activity at their growth temperatures of 48 and 54 degrees C. Thus, the cel operon previously described as a cryptic operon in E. coli and S. typhimurium was found to be expressed at growth-refractory temperatures of the mesophilic parent and growth-permissive temperatures (48 and 54 degrees C) of the thermotolerant and mesothermophilic mutants.
