Does Torulaspora delbrueckii has some probiotic capabilities? In vitro and in vivo assessment

Yeasts are gaining attention as potential emerging tools for enhancing the dietary benefits of food attributes and for preventing food spoilage because of their anti-microbial properties.

In this study, both Torulaspora delbrueckii (T. delbrueckii) as a prospective probiotic and bananas as a prebiotic were used to investigate their potential roles in modulating the lipid content and bacterial number in the feces of examined rats.

Milk has been used to isolate a yeast stain that has been identified using conventional and molecular tools as T. delbrueckii. The isolated yeast showed promising results upon testing for acid and bile tolerance. T. delbrueckii also had the capacity to thrive on simulating stomach and intestinal fluids. According to an animal feeding experiment, rats fed T. delbrueckii developed and acquired mass in a regular manner. Consuming T. delbrueckii also dramatically lowers LDL, cholesterol, and triglyceride levels while dramatically raising HDL levels. Consuming both T. delbrueckii and bananas along with regular animals’ diet considerably reduced the amount of coliforms and Staphylococcus sp. in the rats’ excrement.

These findings suggested a potential function for T. delbrueckii in treating hypocholesteremia and controlling the bacterial flora of the intestine, which can then be used widely after more confirmation of the outcomes.
