A direct-inoculation starter culture, its preparation method and application in mixed fermentation
By co-fermenting Streptococcus thermophilus subsp. ST-G30 and Lactobacillus delbrueckii subsp. bulgaricus LB-G40 in the same culture medium, followed by freeze-drying and compounding with maltodextrin, the problems of low efficiency and high cost in the preparation of direct-inoculation starter cultures were solved, achieving high efficiency and stable fermentation performance.

Abstract
This invention belongs to the field of fermentation agent preparation technology, specifically relating to a direct-inoculation fermentation agent, its mixed fermentation preparation method, and its application. The preparation method of this invention involves co-fermenting *Streptococcus salivarius* subsp. *thermophilus* ST-G30 and *Lactobacillus delbrueckii* subsp. *bulgaricus* LB-G40 in a specific MRSB medium. The resulting fermentation broth is then freeze-dried, and the obtained bacterial powder can be used directly as a fermentation agent. Compared to the method of fermenting single bacteria and then mixing the bacterial powder to prepare the fermentation agent, this method has higher preparation efficiency and does not affect the fermentation performance of the fermentation agent.
