Figure selleck chemical 3 presents cumulative total production of the short chain fatty acids, e.g acetate, propionate and n-butyrate during the different experiments in TIM-2, and represents Poziotinib mw metabolites present in lumen and dialysate. The amount of SCFA present at the start of the experiment has been artificially set to zero so the graphs only reflect the production of metabolites after start of addition of the test products. Figure 3 Cumulative production of the short chain fatty acids (SCFA) acetate, propionate and n-butyrate

during the different experiments in TIM-2: (A) Clindamycin for 7 days (d 1-7 a) followed by VSL#3 (d 8-14 p); (B) Clindamycin + VSL#3 for 7 days (d 1-7 a + p); (C) no therapy group for 7 days (controls). Figure 3D shows the comparison of absolute amounts (in mmol) at the end of each 7 days period. The total SCFA production was not affected by the use of Clindamycin or Clindamycin plus probiotics. When probiotics were administered after the administration of Clindamycin for one week, the SCFA production increased since the slope of the total SCFA production increased in the second week, compared with the first week of the experiment. The production of n-butyrate and propionate was increased

when probiotics R428 were added. The acetate concentration was unaffected by the addition of Clindamycin or probiotics. When Clindamycin and probiotics were administered together the propionate production was decreased. These differences are likely to be caused by changes in the microbiota composition. Figure 4 presents the cumulative total production of lactate. Lactate was produced in all variations, but when probiotics were added the lactate production was increased, independent of the presence of Clindamycin. The probiotics were lactic acid bacteria and the extra production Osimertinib ic50 of lactate proved the probiotics were active in the microbiota. Lactate is only accumulating when there

is a fast fermentation. If substrates are fermented slowly, lactate is converted into the other SCFA (primarily propionate and butyrate) and does not accumulate. Figure 4 Cumulative production of lactate (D- and L-lactate) during the different experiments in TIM-2: (A) Clindamycin for 7 days (d 1-7 a) followed by VSL#3 (d 8-14 p); (B) Clindamycin + VSL#3 for 7 days (d 1-7 a + p); (C) no therapy group for 7 days (controls). Figure 4D shows the comparison of absolute amounts (in mmol) at the end of each 7 days period. The total SCFA production was not affected by the use of antibiotics or antibiotics plus probiotics. When probiotics were added after using antibiotics, the SCFA production increased. Propionate production was decreased when antibiotics and probiotics were used together. Enhanced production of lactate was observed both when probiotics were administrated together with Clindamycin or when they were administered after seven days of clindamycin administration.
