Abstract: 

Background: The aim of this study was to evaluate the ability of b-1, 3-endoglucanase production by B. circulans.
Methods: Bacillus circulans was cultivated in YMB media. In the next step, B. circulans was added to CMC (carboxy methyl cellulose) culture. The protein concentration and endoglucanase activity were measured.
Results: The optimal pH and temperature for high endoglucanase activity in the CMC culture were pH 5.5 and 40oC respectively. Under these conditions, isolate Gu38 with 3×10 -13
mmol/min/ml showed the highest endoglucanase activity in this temperature. Conclusion: This study led us to conclude that Bacillus circulans strain Gu38 may serve as good source of endoglucanase production.
