Effect of Lactobacillus spp. on short-chain fatty acid levels in C57BL/6J mice. C57BL/6J mice (n = 6/group) were grouped into the NC and Amp groups. The groups given the three-strain combination were fed a dose of 1.6 × 108 CFU/mouse (LABL) or 4.8 × 108 CFU/mouse (LABH) from the 3rd day until the 7th day. All groups were analyzed for short fatty acid levels in cecal content samples on the 12th day. Each SCFA standard compound was used for quantitative analysis. The levels of each SCFA were provided in units of “µmol/g cecum content”. Then, the levels were presented as “the percentage of individual SCFA/total SCFA.” (a) Relative levels of retinoic acid, (b) butyric acid, (c) acetic acid, and (d) isobutyric acid. *, compared with NC group, p < 0.05; #, compared with Amp group, p < 0.05.
