Description and Significance

Bacillus amyloliquefaciens is a gram positive soil bacteria closely related to the species Baciullus subtilus. The two species share many homologous genes and appear so similar it is not possible to visually separate the two species. [1] This species is also the source of the commercially available restriction enzyme BamHI which cuts at the palindrome CGATCC. [2]

Structure, Metabolism, and Life Cycle

Bacillus amyloliquefaciens are gram positive rods. The cells have peritrichous flagella allowing motility. The cells often appear as long chains. The optimal temperature for growth is between 30 and 40 degrees Celsius. Similar to other Bacillus species, B. amyloliquefaciens forms endospores allowing survival for a long period of time. Endospores appear centrally in the cells which do not have a swollen appearance. [1]

Ecology and Pathogenesis

Bacillus amyloliquefaciens is a non-pathogenic soil bacterium.
