They are gram-positive, rod-shaped bacteria that are fermentative and endospore-forming. Clostridium produces bottle-shaped endospores. They do not secrete catalase. There are around Clostridium species. They can be free-living or pathogens. Clostridium botulinum food spoilage especially canned foods ; botulism , Clostridium perfringens gas gangrene , Clostridium tetani tetanus and Clostridium sordellii are four Clostridium species that cause human diseases.
Certain Clostridium species are useful in the industrial setting. Bacillus is a genus of aerobic bacteria, which produces oblong endospores and secretes catalase, while Clostridium is a genus of anaerobic bacteria, which produces bottle-shaped endospores.
So, this is the key difference between Bacillus and Clostridium. Besides, Bacillus species belong to class Bacilli, order Bacillales, and family Bacillaceae, while Clostridium species belong to class Clostridia, order Clostridiales, and family Clostridiaceae.
Moreover, another difference between Bacillus and Clostridium is that Bacillus species secrete catalase, while Clostridium species do not secrete catalase. Also, Bacillus forms oblong endospores, while Clostridium forms bottle-shaped endospores.
This is also an important difference between Bacillus and Clostridium. Furthermore, Food poisoning and anthrax are some diseases caused by Bacillus while botulism, gas gangrene and tetanus are caused by Clostridium. Bacillus and Clostridium are two bacterial genera of the phylum Firmicutes. Bacillus species are aerobic bacteria that produce oval-shaped endospores. Moreover, they secrete catalase.
