Ultra-low freezer for bacterial culture collection preservation

本申请要求购买超低温冷冻机，以保持NSERC、行业和行业协会支持的研究中使用的细菌培养物的长期活力。 该研究使用复苏的培养物，重点是食品的微生物生态学，研究致病和腐败生物，以安全延长食品的保质期。以前进行的和计划进行的工作检查影响食品安全的食用动物环境因素。目前要求提供设备的原因是目前使用的冷冻机老化和不可靠，以及它在为大量具有已知工业价值（发酵）的细菌分离物以及具有已知生化或毒性特征的细菌分离物提供安全储存方面的总体重要性。 来自经认可的国际保藏中心的参考菌株也存放在该储存库中。容易获得的培养物的可靠储存在丢失的情况下提供了备份，并允许研究进展的连续性，特别是在从食物链的不同部门获得环境分离物的情况下。该资源允许比较生物体的起源，并允许检查抗菌药物的敏感性，从而可以更好地控制细菌。

This application requests the purchase of an ultra-low temperature freezer to maintain the long term viability of bacterial cultures used in research supported by NSERC, industry and industry-associations. The research, in which resuscitated cultures are used, is focused on the microbial ecology of foods where both pathogenic and spoilage organisms are studied to enable the safe extension of the shelf-life of food products. Work previously conducted and that planned examine factors in the food animal environment that influence food safety. The current equipment request is motivated by the age and unreliability of the freezer presently used, as well as its overall importance in providing safe storage for a large number of bacterial isolates of known industrial value (fermentations) as well as those with known biochemical or virulence characters. Reference strains from accredited international collections are also housed in this storage. Dependable storage of cultures that are readily accessible provides back-up in case of loss, and allows for continuity in the progress of research, particularly where environmental isolates are obtained from different sectors of the food chain. This resource permits comparisons of the origins of organisms and allows for examinations of antimicrobial susceptibility that can lead to better means for bacterial control.
