Bacillus mycoides is a bacterium of the genus Bacillus. Like other Bacillus species, B. mycoides is Gram positive, rod-shaped, and forms spores.
Description
B. mycoides are rod-shaped cells Bacillus mycoides cells are usually larger than 3 micrometers, form chains of cells, can form acid from glucose, and this form is non motile. Its cell body does not swell when sporulating; Using Voges–Proskauer test, B. mycoides produces a positive result. It can also hydrolyse starch. B. mycoides is a common soil organism.[1] B. mycoides is distinct from a number of other Bacillus species in the unusual morphology of the colonies it forms when grown on agar plates. B. mycoides forms hairy colonies that spread out to fill the plate.[2] Furthermore, B. mycoides colonies form a repeating spiral pattern.[3] The first chiral colony pattern was described by Flügge in 1886.[3] B. mycoides has the unusual property of being able to respond to mechanical force and surface structure variations in the media on which it is growing [4]
Uses
Bacillus mycoides are found in common pesticides and are used to inhibit the growth of harmful bacteria and fungi. There seems to be no negative effects on humans or the environment.Citation needed
Nitrogen Cycle
Bacillus mycoides is an ammonifying bacterium, and can convert peptone (protein, an organic nitrogen source) into ammonia. In water, ammonia becomes ammonium. This product is essential for nitrifying bacteria such as Nitrosococcus, which use the ammonia under aerobic conditions to make nitrite.
