Ammonia removal rate of SB and SC in YNB medium with NH4Cl as a nitrogen source in shaking culture (130 rpm). SB, Saccharomyces boulardii CNCM I-1079; SC, Saccharomyces cerevisiae KCTC 7107. Error bars represent the standard error (n = 3). **p < 0.01, ****p < 0.0001, compared between control and yeast treatment groups, indicates statistical significance (SB treatment vs. control: f-value = 52.41, degree of freedom (DF) = 2.0763, t-value = − 24.95, p = 0.0013; SC treatment vs. control: f-value = 2.50, DF = 4, t-value = −19.03, p < 0.0001; SB vs SC treatments: f-value = 1.21, DF = 4, t-value = 0.31, p = 0.7749)
