Brecibacterium is a brand of bacilli of the adjustment Actinomycetales. They are Gram-positive clay organisms. It is the sole brand in the ancestors Brevibacteriaceae.
Brevibacterium linens is ubiquitously present on the animal skin, area it causes bottom odor. The aforementioned bacillus is aswell active to agitate several cheeses such as Limburger, Port-du-Salut and Năsal. Its that appears to smell aswell attracts mosquitoes.
The Brecibacterium brand is a amalgamate admixture of coryneform bacilli that accept accurate appliance to automated assembly of vitamins, amino acids for accomplished actinic production, and are frequently acclimated in cheese assembly (Amador et al., 1999; Rattray and Fox, 1999). This brand contains 9 breed from assorted habitats, such as soil, poultry, fish, animal skin, and food. While Brevibacterium linens is phenotypically agnate to Arthrobacter globiformis cellular pigmentation, corpuscle bank composition, DNA/DNA admixture and 5s RNA assay appearance that Brevibacterium is audibly altered (Park et al., 1987). PFGE assay indicates that assortment aural the breed is accompanying to polymorphisms in the 16S rRNA genes with genome sizes that ambit from 3.2 and 3.9 Mbp (Lima and Correia, 2000).
B. linens is a non-motile, non-spore forming, non-acid fast, Gram-positive coryneform that tolerates top alkali concentrations (8-20%) and is able of growing in a ample pH ambit (5.5-9.5), with an optimum of pH 7.0. They are aswell survive carbohydrate starvation and dehydration for continued periods (Boyaval et al., 1985). B. linens is abnormal as they aftermath abject as they grow, adopting the pH to ~9.5 aural 24-36 hours. Recent absorption in B. linens has focused about their adeptness to aftermath a self-processing extracellular proteases (Rattray et al., 1995; Weimer et al., 2000), their adeptness to aftermath top levels of airy sulfur compounds (Ferchichi et al., 1985; Dias and Weimer, 1998a, and 1998b), bacteriocin assembly (Valdes-Stauber and Scherer, 1996), corpuscle film associated carotenoid colorant assembly (Arrach et al., 2001), and ambrosial amino acerbic metabolism (Leuschner and Hammes, 1998; Ummadi and Weimer, 2001).
