Abstract:
In this study, culture supernatant of Bacillus sp. has been used as crude enzyme source. It has been determined that 1% urea is the optimal substrate concentration for maximal urease activity. On the other hand, Bacillus sp. urease showed its maximal activity at pH:7.0-8.0, 30 degrees C. 50 minutes of incubation has been found to be the most suitable incubation period. The activity of the enzyme showed a 36% decrease when stored at +4 degrees C for a month.
