How is the gelatin medium inoculated

WebTo detect the ability of an isolated specimen to produce gelatinase we inoculated the microorganism in gelatin deep tube by means of a stab inoculation we incubated the gelatin deep tube cultures at 37°C for 48 hours. Then re-incubated all negative cultures for an additional 5 days. WebThis test is used to determine the ability of an organism to produce proteolytic enzymes (gelatinases) that liquefy gelatin. METHOD. Inoculate the gelatin deep with 4 to 5 drops of a 24-hour broth culture. Incubate at 35° C in ambient air for up to 14 days. NOTE: Incubate the medium at 25 ° C if the organism grows better at 25° C than at 35° C.
