Abstract The membrane is the major protective barrier separating cell from environment and thus important for bacteria to survive environmental stress. This study investigates changes in lipid compositions physiology of meat spoiling response high CO 2 (30%) O (70%) concentrations, as commonly used modified atmosphere packaging meat. Therefore, fatty acid profile well fluidity, permeability sur...

Two studies evaluated the proteolysis of alfalfa that was ensiled in laboratory silos under different modified atmospheres. In the first study, fourthcutting alfalfa was ensiled at 25% dry matter (DM) for 28 d. The forage treatments were a modified atmosphere of 3% O2:20% CO2:77% N2, or formic acid (6 ml/kg of fresh weight); an untreated control was used for comparison. Proteolysis was assessed...

The structures of PtNix nanoalloy particles were modified through thermal annealing in different atmospheres. The evolution of surface structures was uncovered by advanced transmission electron microscopy, and the structure-function correlation in methanol electro-oxidation was probed. It provided new insights into the design and synthesis of highly efficient electrocatalysts.

The aim of this study was to preserve the quality and prevent colour, lipid protein oxidation in chicken breast fillet (pectoralis major muscle) during storage. For purpose, modified atmospheres (MA) with four different gas mixtures (vol. %) oxygen (O2 ), carbon dioxide (CO2 ) nitrogen (N2 were used: free (0: 20: 80), low (20: 60), medium (40: 40), high MA (70: 10). After 9 days storage a refri...

Many factors influence the shelf-life, color, and sensory attributes of beef. Packaging is one of those factors. There are several different types of packaging used in the meat industry, including vacuum packaging, overwrap, and modified atmosphere packaging (MAP). Traditionally wholesale cuts are vacuum packaged, boxed, and sent to retailers where they cut the meat, place it on a styrofoam tra...

Cod fillets (Gadus morhua) were packed under modified atmospheres, with four different gas compositions (60% CO2-10% O2-30% N2, 60% CO2-20% O2-20% N2, 60% CO2-30% O2-10% N2, 60% CO2-40% O2), and stored at 6 degrees C. Plate counts were carried out after 3, 4, 5, 6 and 7 days, to follow the growth of aerobic and anaerobic bacteria, lactic acid bacteria, H2S-producing bacteria and Enterobacteriac...

Lipid oxidation, color, volatiles, and sensory evaluation of double-packaged pork loin were determined to establish a modified packaging method that can improve the quality of irradiated pork loins. Vacuum-packaged irradiated samples produced dimethyl sulfide and dimethyl disulfide responsible for irradiation off-odor, whereas lipid oxidation was promoted under aerobic conditions. Exposing doub...

Retroviral vectors were modified to contain packaging (psi) signals of varying lengths (nucleotides 211-355, 211-565, or 211-1039 of MoMuLV RNA) between the U3-r and U5 sequences of their 5' long terminal repeat (LTR). For the vector MoTN-PR3, containing the full length 211-1039 nucleotide-long psi signal within the 5' LTR, replication, integration, and packaging were almost as efficient as for...
