DETECTION OF BACTERIAL GELATINASES BY GELATIN-AGAR PLATE METHODS

Abstract

Two methods for the detection of bacterial gelatinase based upon the production of zonal changes in gelatin-agar media containing low concentrations of gelatin are presented. The zone could be observed directly without the addition of protein precipitants. The effects of various factors on the appearances of the gelatin-agar media and of the zones of gelatin degradation are discussed.
