Ultra-low freezer for bacterial culture collection preservation

此申请要求购买超低温冷冻机，以保持NSERC，工业和行业协会支持的研究中使用的细菌培养物的长期生存能力。这项使用复活培养物的研究重点是食品的微生物生态，研究致病性和腐败性微生物，以安全延长食品的保质期。先前进行的和计划进行的工作检查食品动物环境中影响食品安全的因素。目前的设备需求是由目前使用的冷冻器的年龄和不可靠性所驱动的，以及它在为大量已知工业价值（发酵）的细菌分离物以及具有已知生化或毒力特征的细菌分离物提供安全储存方面的总体重要性。从认可的国际收藏的参考菌株也被安置在这个存储。易于获取的培养物的可靠储存可在丢失时提供备份，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。这一资源允许比较生物体的起源，并允许检查抗菌素敏感性，从而导致更好的细菌控制手段。

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.
