What is Brecibacterium?

Brecibacterium is a genus of bacteria of the order Actinomycetales. They are Gram-positive soil organisms. It is the sole genus in the family Brevibacteriaceae.
Brecibacterium linens is ubiquitously present on the human skin, where it causes foot odor. The same bacterium is also employed to ferment several cheeses such as Limburger, Port-du-Salut and Năsal. Its smell also attracts mosquitoes.
Brevibacterium genus is a heterogeneous mixture of coryneform organisms that have particular application to industrial production of vitamins, amino acids for fine chemical production, and are commonly used in cheese production. This genus contains 9 species from diverse habitats, such as soil, poultry, fish, human skin, and food. While Brevibacterium linens is phenotypically similar to Arthrobacter globiformis cellular pigmentation, cell wall composition, DNA/DNA hybridization and 5s RNA analysis show that Brevibacterium is distinctly different. PFGE analysis indicates that diversity within the species is related to polymorphisms in the 16S rRNA genes with genome sizes that range from 3.2 and 3.9 Mbp
