Desulfurization performance evaluation on Desulfovibrio from the human gut. (a) The change of the medium’s pH value from day 0 to day 4. (b) Comparison of SO₄²⁻ removal rate. The type strain was D. desulfuricans ATCC 29577. The Blue bars were the strains from healthy volunteers, and the red bars were the stains from patients with liver cirrhosis, and the data are given as the means ± standard error of the mean (s.e.m.). Differences were identified using the t-test and One-way ANOVA statistical analysis, and different superscripts indicate significant differences (p < 0.05).
