Advances in salt tolerance and fermentation promotion mechanism of microorganisms in fermented foods under salt stress

Abstract

With the application of physiological and multi-omics technologies, they will be able to accurately analyse the mechanisms of salt tolerance and fermentation promotion of fermentation microorganisms under salt stress, which will lay the foundation for the effective regulation of salt brine fermentation and enhancement of the flavour of traditional fermented foods. The article reviews the common salt-tolerant microorganisms in fermented foods, the main salt-tolerant mechanisms, the fermentation-promoting properties in high-salt environments, and the methods to study the salt-tolerant and fermentation-promoting mechanisms, as well as the future direction of their development.
