Complete Genome Sequences of Two Strains of the Meat Spoilage Bacterium Brochothrix thermosphacta Isolated from Ground Chicken
Brochothrix thermosphacta is an important meat spoilage bacterium. Here we report the genome sequences of two strains of B. thermosphacta isolated from ground chicken. The genome sequences were determined using long-read PacBio single-molecule real-time (SMRT) technology and are the first complete genome sequences reported for B. thermosphacta.
متن کاملEnd Products of Glucose Fermentation by Brochothrix thermosphacta.
Anaerobically, Brochothrix thermosphacta fermented glucose primarily to l-lactate, acetate, formate, and ethanol. The ratio of these end products varied with growth conditions. Both the presence of acetate and formate and a pH below about 6 increased l-lactate production from glucose. Small amounts of butane-2,3-diol were also produced when the pH of the culture was low (</=5.5) or when acetate...
متن کاملThe microbiology of meat spoilage: a review
The microorganisms most commonly involved in meat spoilage are Pseudomonas spp., the Enterobacteriaceae family, lactic acid bacteria and the Brochothrix thermosphacta. The factors that are considered to have the main effect on the speed of spoilage and the shelf life of fresh meat are intrinsic factors (initial number of psychrotrophs present on the meat surface, water activity, the pH value an...
متن کاملcontrol of brochothrix thermosphacta in pork meat using lactococcus lactis subsp. lactis i23 isolated from beef
this study evaluated the antimicrobial activities of two lactic acid bacteria, lactococcus lactis subsp. lactis i23 and lactococcus lactis subsp. lactis e91, against brochothrix thermosphacta in pork meat during storage at ambient temperature (30°c) for 168 h. the lab strains and the spoilage organism were inoculated on fresh pork samples at 1×106 cfug-1. results showed about 3 log reduction in...
متن کاملInsight into the Genome of Staphylococcus xylosus, a Ubiquitous Species Well Adapted to Meat Products
Staphylococcus xylosus belongs to the vast group of coagulase-negative staphylococci. It is frequently isolated from meat products, either fermented or salted and dried, and is commonly used as starter cultures in sausage manufacturing. Analysis of the S. xylosus genome together with expression in situ in a meat model revealed that this bacterium is well adapted to meat substrates, being able t...
