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 کاملEffect of modified atmosphere composition on the metabolism of glucose by Brochothrix thermosphacta.
The influence of atmosphere composition on the metabolism of Brochothrix thermosphacta was studied by analyzing the consumption of glucose and the production of ethanol, acetic and lactic acids, acetaldehyde, and diacetyl-acetoin under atmospheres containing different combinations of carbon dioxide and oxygen. When glucose was metabolized under oxygen-free atmospheres, lactic acid was one of th...

Regulation of the glucose-specific phosphotransferase system (PTS) of Staphylococcus carnosus by the antiterminator protein GlcT.
The ptsG operon of Staphylococcus carnosus consists of two adjacent genes, glcA and glcB, encoding glucose- and glucoside-specific enzymes II, respectively, the sugar permeases of the phosphoenolpyruvate-dependent phosphotransferase system (PTS). The expression of the ptsG operon is glucose-inducible. Putative RAT (ribonucleic antiterminator) and terminator sequences localized in the promoter r...
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, ...
