Technical Abstract: At the present time, the activities or strengths of commercial dextranases in the U.S. cannot be directly compared because there is no uniform method used by vendors to measure the activity. A very wide variation exists in the activities of commercial dextranases, and this is compounded by the fact that activities and prices can change regularly. Furthermore, the factory storage characteristics of commercial dextranases differ widely which further highlights the urgent need for not only a uniform method to (a) measure and economically compare the activities of different commercial dextranases, but (b) one which can be used easily at the factory or refinery. A dextranase method, based on simple titration, was identified and modified for easy use at the sugarcane factory/refinery. This method does not need any sophisticated equipment and there is no need for standards and a standard curve.
