title: [The medium for determining the gelatinase activity of non-fermenting gram-negative microorganisms].
abstract: To determine the gelatinase activity of Gram-negative nonfermenting microorganisms, a double-layer medium containing 2% of agar in the lower layer and 10-20% of gelatin in the upper layer has been developed. The medium ensures free access of atmospheric oxygen, possibility of rapid (24-42 h) determination of gelatinase activity at 22-25 degrees C, efficacy of the test. simultaneous determination of gelatin hydrolysis by 8-12 strains in one dish.
