The abundance of Dorea sp. correlates with the concentrations of SCFAs and growth-related hormones. A The sizes of the squares or circles are scaled according to the correlation degree. The intensities of blue and red colors indicate values of positive and negative correlation coefficients, respectively (n = 16). B CCA between species and SCFAs (n = 16). C In vitro growth of Dorea sp. CML553 on graded concentrations of AOS and glucose (n = 3). D SCFAs production in batch cultures containing 0.3% AOS or glucose (n = 3). Data are expressed as the mean ± SD. ^*P < 0.05, ^**P < 0.01
