The application provides a torulopsis pullulans engineering strain and a construction method and application thereof, and belongs to the field of microorganisms and food biotechnology. The application provides a torulopsis pullulans DL-XKX01 engineering strain with high ergothioneine production capacity. The RNA interference technology is used to inhibit the carotenoid synthesis pathway which competes with ergothioneine for substrates, so as to improve the ergothioneine production capacity. The ergothioneine level of the torulopsis pullulans DL-XKX01 provided by the application can reach 116.24+ / -4.33 mg / L in a flask fermentation, and can reach 858.18+ / -5.23 mg / L in a fermenter. The torulopsis pullulans DL-XKX01 can be used to improve the ergothioneine content in fermented food and improve the food quality, and has a good industrial application prospect.

The present application relates to the field of microbial technology, and particularly to a strain of Gluconobacter oxydans and its application. Gluconobacter oxydans The present application provides a strain of Gluconobacter oxydans (Gluconobacter oxydans) named KUST4611, which has been preserved in the Guangdong Microbial Culture Collection Center on October 22, 2025, with a preservation number of GDMCC NO: 67143. The volatile substances produced by the strain provided by the present application during growth have a bacteriostatic effect. When the strain is applied to prepare a fresh-keeping gel, the volatile substances produced by the gel placed in a closed space can achieve good fresh-keeping effect, effectively reduce the occurrence of diseases, maintain the freshness of the peppers, and effectively prolong the fresh-keeping period of the peppers. Meanwhile, the preparation method of the fresh-keeping gel is simple, and the fresh-keeping effect can be easily and conveniently achieved, the cumbersome steps of postharvest preservation are reduced, and the postharvest preservation efficiency is further improved.
