Abstract: | Background Many workers have reported halotolerant bacteria from saline conditions capable of protease production. However, antibiotic
resistance and heavy metal tolerance pattern of such organisms is not documented very well. Similarly, only a few researchers
have reported the pattern of pH change of fermentation medium during the course of protease production. In this study, we
have isolated a halotolerant Bacillus cereus SIU1 strain from a non-saline environment and studied its antibiotic and heavy metal resistance pattern. The isolate produces
a thermoalkaline protease and changes the medium pH during the course of fermentation. Thermostability of protease was also
studied for 30 min. |
