Protease is a complex enzyme that plays a role in its application in the physiological field and commercial products. The aims of this research were to protease enzyme producing bacteria, to know the protease enzyme activity of bacteria isolate from water swamp and identify protease enzyme producing bacteria. This research was conducted by using laboratory experimental method and the data was analyzed descriptevely.  The result of this research indicates that the Tanjung Senai AR₁TS₁ show the activity of protease enzyme and produce the highest proteolitic index among the other samples.  Basedon Gram staining test, morphology of bacterial cell, motility test, catalase test, suger fermentation tes and H₂S, oxigen needed test that kind of bacteria for AR₁TS₁ isolate was Liseria.
