Abstract

In order to obtain a compound probiotic with a better comprehensive ability to lower blood glucose and lipid levels, this study tested the effectiveness of eight commonly available probiotics in blood glucose lowering abilities, cholesterol clearance, gastrointestinal tolerance, and other activities in vitro.Principal component analysis was used to screen out strains with better comprehensive ability by taking the measured indicators as factors.Antagonism analysis was then performed among the strains, and the optimal proportion of compound probiotics was also determined.Additionally, a preference analysis for prebiotics was performed on the compound probiotic.The results showed that Lactobacillus plantarum CFFM1031 and Bifidobacterium lactis CFFM2012 were the most effective strains in reducing blood glucose and lipid levels.No antagonistic effect was observed between these two strains.The study found that a compound with a 1:1 ratio of L.plantarum CFFM1031 and B.lactis CFFM2012 significantly lowered cholesterol by 43.56% in vitro compared to single strains and other compound ratios.Moreover, the compound probiotic exhibited a higher proliferation ability when galacto-oligosaccharide and stachyose were used as carbon sources, indicating a preference for these sources.This study can provide a reference for probiotic synergism and the development of functional food formulations.
