Warner reveres their college students, and therefore value appears to help them consume training and you may come up with their own expertise. Reuben Clark Laws College or university, got Warner’s Guide from Mormon category on 1970s.

Relationships anywhere between cup changeover temperature, and you can desiccation as well as heat threshold for the Salmonella enterica

Pathogenic bacteria such as Salmonella enterica exhibit high desiccation tolerance, enabling long-term survival in low water activity (aw) environments. Although there are many reports on the effects of low aw on bacterial survival, the mechanism by which bacteria acquire desiccation tolerance and resistance to heat inactivation in low-aw foods remains unclear. We focused on the glass transition phenomenon, as bacteria may acquire environmental tolerance by state change due to glass transition. In this study, we determined the glass transition temperature (Tg) in S. enterica serovars under different aw conditions using http://datingranking.net/pl/arablounge-recenzja thermal rheological analysis (TRA). The softening behaviour associated with the state change of bacterial cells was confirmed by TRA, and Tg was determined from the softening behaviour. Tg increased as the aw ple, while the Tg of five S. enterica serovars was determined as °C to °C at 0.87 aw, the Tg of all the five serovars increased by °C to °C at 0.43 aw. Furthermore, to verify the thermal tolerance of bacterial cells, a thermal inactivation assay was conducted at 60°C for 10 min under each aw condition. A higher survival ratio was observed as aw decreased; this represented an increase in Tg for Salmonella strains. Ler mais
