Bacillus cereus
Bacillus cereus
Bacillus cereus (pronounced: /bəˈsɪləs ˈsɪriəs/) is a Gram-positive, rod-shaped bacteria that is commonly found in soil and food. It is known for its ability to form spores that are resistant to heat, cold, radiation, and disinfectants.
Etymology
The name Bacillus cereus was first proposed by Frankland and Frankland in 1887. The genus name Bacillus (from the Latin baculus, meaning "stick") refers to the rod-like shape of the bacteria. The species name cereus (from the Latin cereus, meaning "waxy") refers to the appearance of the colonies on a Petri dish, which resemble wax.
Characteristics
Bacillus cereus is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. It is also mesophilic, preferring moderate temperatures for growth. The bacteria produce endotoxins that can cause food poisoning, with symptoms including vomiting and diarrhea.
