Spores occur in soil, on bird feathers and in ground dwelling birds and aquatic species; comprise the subtilis group, which has been associated with food-borne gastro-enteritis. Current research try to find the "death kinetics" (2) of these bacteria. An arrangement is a microbiological term that refers to species-specific bacteria communities. Bacillus subtilis morphology describes rod-shaped, Gram-positive bacteria that show up on both positive and negative Gram stain techniques.

Currently there are many electrical techniques for food processing, one such example is Ohmic heating. Bacillus subtilis is a Gram-positive, rod-shaped bacterium that is the type species of the genus Bacillus, commonly used as a model organism to describe the structure of different species of the genus. The protease has an optimum pH at around 9 and 10, which is desirable since it can remove protein-comprised dirt in clothes. ducks) are common carriers of this bacterium; it is mostly found around the bird's chest area and back plumage.

But, although similar to B. subtilis, they differ in the amount and location of prophages, transposable elements, extracellular enzymes, and secondary metabolic pathway operons. The complete nucleotide sequence of Bacillus licheniformis consists of the ATCC 14580 genome, which has a circular chromosome of 4,222,336 bp (base pairs) which contains 4,208 predicted protein-coding genes (average size of 873 bp), 7 rRNA operons, and 72 tRNA genes.
