Brucella agar is nonselective and often used for recovering anaerobic bacteria. The starch absorbs toxins released by the bacteria. Mueller Hinton agar is used for antimicrobial susceptibility testing and is neither selective nor differential. Artificial microbiological culture media provide all the essential environmental and nutritional requirement of the organism(s) to be culture because virtually all pathogenic microorganisms and some commensals are chemoorganoheterotrophic in their mode of nutrition and rarely produce their own food. It allows the growth of almost all types of organisms. It is considered a ‘loose’ agar, which helps to mediate the rate of diffusion of the antimicrobial more effectively than other types of media. Incubate … The cell suspensions were swabbed evenly on the surface of Mueller-Hinton agar plates using sterile cotton swabs. Gamma hemolysis is used to describe the absence of hemolysis. Beta hemolysis is characterized by complete lysis of the red blood cells, whereas alpha hemolysis is incomplete lysis and results in a greenish zone around the colony. It is selective because, this growth medium contains a good amount of salt, thereby inhibiting the growth of almost all bacteria, except those in the genus Staphylococcus.So it is used for isolating staphylococci bacteria. Mueller Hinton Agar has been selected by … Another type of differential/selective media is the Mueller-Hinton agar plate.
