Blood agar plate This test is used to detect the hemolytic activity in the bacteria. A darkish green color on the media around the bacteria would represent incomplete hemolysis. A transparent media around the bacteria colony represents complete lysis of the red blood cells. If no change is observed around the bacteria colony then the bacteria is non-hemolytic. For my bacteria no change is observed in the media therefore the bacteria is non-hemolytic and negative result. MacConkey Agar test

A 10 microliter aliquot from each dilution will be placed on a 5% blood agar plate or a MacConkey plate‚ depending on the type of organisms plated. These plates are selected because of the ease of differentiation between organisms. The original vial and all diluted aliquots will then be refrigerated to restrict growth until
