  1. a-e Means in the same column followed by different superscript letters are significantly different (P < 0.05)
  2. 1Strains LP: Lactobacillus plantarum; LF: Lactobacillus fermentum; LB: Lactobacillus brevis; LA: Lactobacillus acidophilus
  3. 2Cholesterol reduction rate/% = (1-C1/C0) × 100; C0 is the cholesterol content in the control broth (mg/L), and C1 is the cholesterol content in the supernatant of the inoculated strain broth (mg/L)
  4. 3Acid resistance (%) = (N1/N2) × 100; N1 is the total number of viable cells of strain in MRS broth at 3 h, and N2 is the total number of viable cells of strain in MRS broth at 0 h
  5. 4Bile resistance (%) = (logN1/ log N2) × 100; N1 is the total number of viable cells of strain in MRS broth (pH 8.0) with 0.3% oxgall Bile, and N2 is the total number of viable cells of strain in MRS broth (pH 6.2) without oxgall Bile
