Pressure Resistance

Formulations with lactate as an antimicrobial and high-pressure processing (HPP) as a lethal treatment are combined strategies used to control L. monocytogenes in cooked meat products. Previous studies have shown that when HPP is applied in products with lactate, the inactivation of L. monocytogenes is lower than that without lactate. The purpose of the present work was to identify the molecular mechanisms underlying the piezo-protection effect of lactate. Two L. monocytogenes strains (CTC1034 and EGDe) were independently inoculated in a cooked ham model medium without and with 2.8% potassium lactate. Samples were pressurized at 400 MPa for 10 min at 10 °C. Samples were subjected to RNA extraction, and a shotgun transcriptome sequencing was performed. The short exposure of L. monocytogenes cells to lactate through its inoculation in a cooked ham model with lactate 1h before HPP promoted a shift in the pathogen’s central metabolism, favoring the metabolism of propanediol and ethanolamine together with the synthesis of the B12 cofactor. Moreover, the results suggest an activated methyl cycle that would promote modifications in membrane properties resulting in an enhanced resistance of the pathogen to HPP. This study provides insights on the mechanisms developed by L. monocytogenes in response to lactate and/or HPP and sheds light on the understanding of the piezo-protective effect of lactate.

Aimed at SUV-type vehicle, simulation and analysis of pressure resistance experiments on the body of automobile has been presented in the paper, according to the vehicle safety regulations and standards of FMVSS216. A limited SUV vehicle model is created; simulation is obtained with the help of software LS-DYNA, based on the principle of finite element analysis method. Assessment of pressure resistance and safety of the automobile has been presented, from the aspect of the deformation of body, the energy absorption of the vehicle and components, and the pressure on the body, etc. By rational improving of the original design of body structure, the reasonable distribution of pressure absorbability of the body of the SUV-type automobile is achieved. The effect of the overall energy absorption of the body is fully exerted, and then the safety of the driver and the passenger in a rollover accident is improved. Research methods and conclusions of this paper provide useful ways and references to the research of the safety of vehicle rollover and design of rationality of body energy absorption
