Media are used to grow bacterial colonies (millions of bacteria having arisen through the binary fission of a single progenitor). Article Summary: Blood Agar is a bacterial growth medium that can distinguish normal from pathogenic bacteria based on the effect of bacterial hemolytic exotoxins on red blood cells.
Bacteria growing on blood agar can be classified in part on what they do to the red blood cells incorporated into the medium. Some bacteria produce hemolysins, enzymes that destroy red blood cells (hemo = blood, lysin = to split).Hemolysins can destroy the cells and release the hemoglobin into the medium.As the hemoglobin is exposed to the chemicals in the agar, its characteristic red color is altered. This type of hemolysis, alpha-hemolysis, turns the medium under the bacterial growth brown-green.emolysins can destroy the cells and release the hemoglobin into the medium.
