Abstract:
This research verified the in vitro study of short chain fatty acids (SCFAs) extract and cell-free supernatant (CFS) produced from various probiotic Lactobacillus strains and evaluated its function of anti-obesity. The production of SCFAs produced from the combination of L. paracasei SD1 and L. rhamnosus SD11 provided the highest SCFAs content at fermentation at 24 h and 45°C. The CFS exhibits a markedly stronger ability to prevent adipogenesis compared to the extract. Specifically, the combination of L. paracasei SD1 and L. rhamnosus SD11 demonstrates the highest suppression of lipid accumulation in 3T3-L1 adipocytes. It was observed that the CFS had a dose-dependently inhibitory effect on adipocyte differentiation, which was linked to a significant downregulation of gene expression levels of C/EBP-β, C/EBP-α, PPARγ, FAS, and LPL. The findings revealed the possibility of utilizing the CFS as a functional food due to its anti-obesity abilities by suppression of adipogenesis/lipogenesis in 3T3-L1 adipocytes.
