ABSTRACT The present study describes the characterization of crude protease extract from Arthrobacter arilaitensis Re117 and its evaluation in solid and liquid detergent. One caseinolytic protease clear band was observed in zymogram. The crude alkaline protease showed optimum activity at pH 9.0 and 50°C, and it was highly stable over a wide range of pH ...
