This application discloses a trough fermentation system for lignite fermentation, including a fermentation trough and a heating device for heating the fermentation trough. A floor heating coil is installed at the bottom of the fermentation trough. The heating device supplies heat to the fermentation trough through the floor heating coil, providing different amounts of heat to the fermentation trough in the early, middle, and late stages of fermentation, respectively, so that the fermentation trough is in the first, second, and third stages. The gradient temperature control of this application can accurately meet the temperature requirements of different stages in the fermentation process, significantly improving fermentation efficiency, accelerating the fermentation process, significantly shortening the fermentation cycle, and reducing greenhouse gas emissions, thus offering environmental advantages.

This invention relates to the field of microbial technology, specifically to Kluyveromyces martensii YF51-1 and its application in semi-dry fermented whey wine. This strain can efficiently ferment lactose and galactose, while also exhibiting a high ABTS scavenging rate. The fermentation broth contains a high amount of amino acid nitrogen. Under conditions where sucrose is present, the amino acid nitrogen content in the sweetened whey fermentation broth is significantly higher than that in the unsweetened whey fermentation broth. Through process optimization, the optimal fermentation conditions for strain YF51-1 were obtained, ultimately producing a semi-dry whey fermented wine with a rich aroma and a sweet and sour taste, achieving an amino acid nitrogen content of 0.337 g / L, significantly higher than existing technologies. Through optimization of the freeze-drying process, a freeze-drying protectant suitable for strain YF51-1 was derived. This protectant consists of mannose, corn steep liquor powder, lysine, and calcium chloride. After optimization, this protectant demonstrates good protective effect on the strain, with a survival rate of up to 97.22%.
