Zusammenfassung: | The invention relates to a low-temperature-resistant high-sugar-yield Torulaspora delbrueckii strain and application thereof. The invention is characterized in that the strain is named YT-22, the classification designation is Torulaspora delbrueckii, the strain is collected by China General Microbiological Culture Collection Center on July 3rd, 2014, and the collection number is CGMCC No.9408. The Torulaspora delbrueckii has normal fermenting property at 15-40 DEG C, can generate abundant reducing sugar in the dough fermentation process. When being mixed with other microbes, the Torulaspora delbrueckii can provide abundant nutrient substances for other strains in the fermentation process, promote metabolism of the other strains and obviously enhance the fermentation characteristics of the other microzymes and lactobacillus. When being added into the dough, the Torulaspora delbrueckii can lower the toughness of the dough under the fermentation action and improve the ductility of the dough, so that the finally obtained steamed bread has favorable quality. |
