RESUMO
Five mutants of Bacillus subtilis 168 defective in an intracellular esterase activity were identified. By polyacrylamide gel electrophoresis, four of the mutants were shown to lack esterase B activity, and the fifth lacked esterase A activity. All of the back-crossed esterase mutants were able to sporulate at wild-type frequency and produce exoprotease(s) and antibiotic(s). No difference in motility could be attributed to the esterase mutation. PBS1 transduction analysis showed all the esterase B mutations to be linked to the hisA marker.
