Clostridium perfringens
Clostridium perfringens Clostridium perfringens
Clostridium perfringens grown anaerobically on blood agar at 37 ° C for one day. Cl. perfringens is the obligate anaerobic, but one of the clostridial that can grow at a relatively high value of the Eh.
 Clostridium perfringens is large box-shaped rods. There is normally no spores, since the formation of these require alkaline conditions.

There is prepared a dilution series of Clostridium perfringens plated in PCA and incubated aerobically at 25° C for three days. As the incubation is carried out aerobically, some of the colonies growing on the surface. It is the large off-white colonies. Colonies which lies between the agar and the petri dish is smaller and more transparent. Colonies which is located in the agar is lenticular.
