End 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 کاملOrigins of Highly Mosaic Mycobacteriophage Genomes
Bacteriophages are the most abundant organisms in the biosphere and play major roles in the ecological balance of microbial life. The genomic sequences of ten newly isolated mycobacteriophages suggest that the bacteriophage population as a whole is amazingly diverse and may represent the largest unexplored reservoir of sequence information in the biosphere. Genomic comparison of these mycobacte...
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...
متن کاملReduction of Brochothrix thermosphacta on beef surfaces following immobilization of nisin in calcium alginate gels.
Lean and adipose beef carcass tissues inoculated with Brochothrix thermosphacta (BT) (approx. 4.50 log10 cfu cm-2) were left untreated (U) or treated with 100 micrograms ml-1 nisin (N), calcium alginate (A) or 100 micrograms ml-1 nisin immobilized in a calcium alginate gel (AN). Tissue samples were refrigerated after treatments and bacterial populations and nisin activity were determined at 0, ...
متن کاملGrowth of Brochothrix thermosphacta in ground beef following treatments with nisin in calcium alginate gels
Sterilized, lean and adipose beef carcass tissues were inoculated with Brochothrix thermosphacta, left untreated (U), or treated with 100 μg/ml nisin (N), calcium alginate (A), or 100 μg/ml nisin immobilized in a calcium alginate gel (AN). Treated tissues were aseptically processed into ground beef and populations of B. thermosphacta and nisin activity were determined during refrigerated storag...
