Stenotrophomonas maltophilia Gd2: A potential and novel isolate for fibrinolytic enzyme production.

ABSTRACT: The bacterium with an ability to produce extracellular fibrinolytic protease was isolated and identified as Stenotrophomonas maltophilia Gd2 based on ribotyping. The in-vitro fibrinolytic profile of this enzyme depicted 73% of fibrin clot dissolution within 4 h. Fibrinolytic enzyme yield influenced by different physiological (incubation time, temperature, agitation and pH), nutritional (macronutrients such as carbon and nitrogen sources) and biological (inoculums age and inoculums concentration) parameters of fermentation which were optimized based on one-factor-at-a-time (OFAT) approach. The enzyme yield improved from 886 to 1795 FU ml-1 upon OFAT; optimized conditions include temperature - 33 °C, pH - 8.0, incubation time - 36 h, agitation - 150 RPM, 3% v/v inoculums and age of inoculum
