Studies on the Protease ofPseudomonas

Abstract
The purification of the protease of Ps. myxogenes sp., was carried out with the filtrate of a shaking culture of a medium containing glucose of a high concentration, and by application of the following methods, salting out, rivanol treatment, and fractional precipitation with acetone; it was finally succeeded to crystallize the enzyme in a needle-like form obtaining a good yield. This protease preparation was found to reveal homogeneous nature of the electrophoresis at pH 8.07, and further experiments on other physico-chemical and general properties of the preparation were investigated.
