Table 1 Hydrolysis results for actinomycetes grown in blood agar medium

Hemolytic reaction on the Blood agar plate was observed by lifting Petri to the light source, the results of hemolytic activity can be seen in table 1. There are 3 types of hemolysis namely beta hemolysis (β), alpha hemolysis (α), and gamma hemolysis (γ). Beta hemolysis (β) or commonly called total hemolysis is defined as the lysis of all red blood cells. A clear zone, close to the color of the transparency of the base media and surround the colony. Many species of bacteria produce toxins or poisons that can destroy red blood cells. Some species display various levels of beta hemolysis.

将培养皿（Petri）举至光源处可观察血琼脂平板（Blood agar plate）上的溶血反应，溶血活性的检测结果详见表1。溶血反应共分为3类，分别为β溶血（beta hemolysis）、α溶血（alpha hemolysis）与γ溶血（gamma hemolysis）。其中β溶血又称完全溶血，其定义为可裂解全部红细胞，会在菌落周围形成与基础培养基透明度色泽相近的透明环。诸多细菌可产生能够破坏红细胞的毒素或毒性物质，部分菌种可表现出不同程度的β溶血。
