Hemolysis (microbiology) - Wikipedia

WebAlpha hemolysin enzyme catalyzes this process. It is a bacterial enzyme produced by several bacterial species such as S. pneumoniae, Streptococcus mitis, S. mutans, and S. salivarius, etc. When these bacteria are grown in blood agar medium around their colonies, greenish colour develops due to the incomplete destruction of red blood cells. WebBeta-hemolysin breaks down the red blood cells and hemoglobin completely. This leaves a clear zone around the bacterial growth. Such results are referred to as β-hemolysis (beta hemolysis). Alpha-hemolysin partially breaks down the red blood cells and leaves a greenish color behind. This is referred to as α-hemolysis (alpha hemolysis). business management technology magazine
