Definition of hemolysin
WebBlood agar is a solid growth medium that contains red blood cells. The medium is used to detect bacteria that produce enzymes to break apart the blood cells. This process is also termed hemolysis. The degree to which the blood cells are hemolyzed is used to distinguish bacteria from one another. The blood agar medium is prepared in a two-step ... Webα-Hemolysin is a water-soluble protein that undergoes several conformational changes from the time it is released from Staphylococcus until it interacts with a plasma membrane. Initially hemolysin is a monomer, which undergoes oligomerization into a homo-oligomeric ring finally inserting into the lipid bilayer forming a pore.
