a gelatinase positve bacteria was inoculated into gelatinase agar and incubated at 25 c. as expected it liquified, what would happen to the tube if it was rhen pkaced in an ice bath?

stay liquid...?

Expert Solution

Gelatinase test is used for testing the capability of certain bacteria to liquify the gelatin in the medium. The organism is inoculated on the agar and incubated at 250C. If the bacteria is positive, it will liquify the medium. To check whether liquification has occured, the medium after incubation is placed in ice bath or at a temperature of 40C.If the medium has liquified, at lower temperature it will get gelled again. This is a confirmation of liquification. So when placed in an ice bath, the gelatinase positive bacteria containing medium will form the gel again and will not stay in liquid form.

E. Coli bacteria were added to 15 petri dishes and they were incubated for 24 hours. The “soap” dishes contained a solution prepared from ordinary soap; the “control” dishes contained a solution of sterile water. The number of bacteria colonies present in each dish after 24 hours are given below:Soap: 76 27 16 30 26 46 6Control: 30 36 66 21 63 38 35 45The numbers of bacteria colonies in the soap dishes come from a normal distribution with mean...
