How do you prevent Brochothrix Thermosphacta?

Application of bacteriocins in meat and meat products, including poultry products, is reported widely, including (1) sanitization of beef carcasses to reduce the populations of Brochothrix thermosphacta, Carnobacterium divergens, or Listeria innocua and inhibit spoilage bacteria with shelf-life extension of vacuum- …

Is Brochothrix Thermosphacta a bacteria?

Brochothrix belongs to the low-GC branch of Gram-positive bacteria (Firmicutes), closely related to Listeria, Staphylococcus, Clostridium, and Bacillus. Brochothrix thermosphacta is a nonproteolytic food spoilage organism, adapted to growth in vacuum-packaged meats.

Where is Brochothrix Thermosphacta found?

Brochothrix thermosphacta has frequently been isolated from hogs and pork carcasses as well as from beef, lamb, poultry, fish, and a variety of other foods (frozen vegetables, tomato salad, and dairy products). The organism has also been isolated from processing equipment and animal feces.

What is Brochothrix SPP?

Brochothrix spp. is a common spoilage organism of meat and meat products stored at chilled temperatures. B. thermosphacta and Brochothrix campestris are the two species assigned to the genus Brochothrix.

What is brochothrix thermosphacta?

Among them, Brochothrix thermosphacta has been the most frequently reported since it is the most versatile species, adapted to the vast diversity of meat products.

What is the optimal pH of bacteria thermosphacta?

The optimal pH was neutral and growth possible till pH = 4.8 for the two strains, assuming possible applications of the bioprotective strain in lightly marinated seafood. The μ (max) of B. thermosphacta in shrimp was a little higher than in L. piscium whatever the environmental conditions.

How much NaCl is required for B thermosphacta to grow?

No NaCl was required for growth and the NaCl (max) was three-times higher for B. thermosphacta than for L. piscium (62 and 23 g l (-1) respectively). However, tolerance to NaCl was higher in seafood than in liquid broth, possibly due to presence of osmoltically active molecules.

How many species of brochothrix are there?

Occasional strain grows. Currently, the genus Brochothrix contains two species, Brochothrix thermosphacta and Brochothrix campestris, which are biochemically similar.
