Psychrophilic bacteria are a type of microorganisms that normally grow in low-temperature environments. They are usually found in extremely cold environments. However, as people's demand for low-temperature storage of food becomes higher, psychrophilic bacteria have also begun to appear in cold storage and refrigerators, which has become a food safety hazard. In this paper, the optimal cooling strategies of psychrophilic bacteria are reviewed from the aspects of the cell membrane, psychrophilic enzymes, antifreeze proteins, cold shock proteins, gene regulation, metabolic levels and antifreeze agents, and the principle of psychrophilic mechanism is briefly described. The application of thermophilic bacteria and its products adapted to cold environments in food fields are analyzed. The purpose of this paper is to provide ideas for future research on psychrophilic bacteria based on the mechanism and application of psychrophilic bacteria.
嗜冷菌是一类通常在低温环境中生长的微生物，它们通常存在于极冷的环境中。然而，随着人们对低温储存食物的需求不断提高，嗜冷菌也开始出现在冷藏库和冰箱中，这成为了食品安全隐患。本文从细胞膜、嗜冷酶、抗冻蛋白、冷休克蛋白、基因调控、代谢水平和抗冻剂等方面综述了嗜冷菌的最佳冷却策略，并简述了嗜冷机制的原理。分析了嗜温菌及其适应冷环境的产品在食品领域的应用。本文旨在基于嗜冷菌的机制和应用为未来的嗜冷菌研究提供思路。
