Abstract:
A comparative proteomic study was performed, revealing meat-spoiling bacteria to counteract substrate competition by different preferences and further differently adapt their metabolism to the detrimental effects of O2 and CO2, both enabling coexistence and synergistical spoilage of modified atmosphere-packaged meat. Bacterial O2-uptake rates were determined and a high throughput prediction method for meat spoilage based on the O2-content of individual meat packages was validated. Furthermore, growth of Pseudomonas on anoxically packaged meat was proven and referred to its arginine fermentation.
