AI Technical Summary

Technical Problem

Existing technologies lack strains capable of efficiently degrading ethyl carbamate (EC) and urea, especially in acidic environments. Furthermore, existing strains exhibit low EC hydrolase and urease activity, making them unable to adapt to the harsh conditions of brewing processes such as high temperatures and ethanol, and thus unable to impart a variety of flavor compounds to brewed foods.

Method used

A novel *Neobacillus mesonae* strain (CGMCC No. 25846) was provided. This strain has high EC hydrolase and urease activity, can efficiently degrade EC and urea in acidic environments, and maintains its activity under high temperature and ethanol conditions. It can also metabolize and produce a variety of flavor compounds.

Benefits of technology

This strain can efficiently degrade EC and urea, adapt to the harsh conditions in the brewing process, and bring a variety of flavors to fermented foods such as baijiu, huangjiu, and soy sauce, significantly improving the quality of fermented foods.
