Volatile organic compounds and Photobacterium phosphoreum associated with spoilage of modified-atmosphere-packaged raw pork.
Accumulation of volatile organic compounds was monitored in association with sensory quality, bacterial concentrations and culture-independent microbial community analyses in raw pork loin and pork collar during storage under high-oxygen modified atmosphere at +4 °C. Of the 48 volatile compounds detected in the pork samples, the levels of acetoin, diacetyl and 3-methyl-1-butanol had the highest...
متن کاملComplete 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 کاملSpoilage of vacuum-packaged dark, firm, dry meat at chill temperatures.
The flora of vacuum-packaged dark, firm, dry meat included thred organisms not usually found on vacuum-packaged meat, Yersinia enterocolitica, Enterobacter liquefaciens, and Alteromonas putrefaciens. Y. enterocolitica did not affect the meat quality. Production of spoilage odors by E. liquefaciens could be prevented by addition of glucose or citrate to the meat. Greening of meat could be preven...
متن کاملReductions of Listeria innocua and Brochothrix thermosphacta on beef following nisin spray treatments and vacuum packaging
Sections of UV sterilized lean and adipose tissues from the surfaces of post-rigor (24 h post-mortem) beef carcasses were inoculated with Brochothrix thermosphacta or Listeria innocua to obtain approximately 4·50 log10 cfu cm and subjected to spray treatments with sterile water or nisin (5000 AU ml). Untreated and spray treated samples were vacuumpackaged, and incubated at 4°C for up to 4 weeks...
