Cholesterol-lowering ability of heat-killed bacteria.
B. longum UBC-15 and L. reuteri UBC-61 were autoclaved at 121℃ for 15 min. The growing (□) and heat-killed (■) cells of the two strains were inoculated in MRS broth containing 100 μg/ml cholesterol and cultured at 37℃ for 24 h. After incubation, the cholesterol concentration in the supernatant was measured. Control was not inoculated with the bacteria. Results are presented as means ± SD, n = 3. **p < 0.01, ***p < 0.001 compared with the control; ns: no significant difference between growing and heat-killed cells.
