Growth of three bacterial isolates on BWX30 and xylose substrates. (A through D) Growth kinetics were recorded using time-series measurements of OD600. Each point on the growth curve represents the mean, and the shaded regions represent a 95% confidence interval of three biological replicates. (E through J) The absolute abundance of each strain in monoculture and coculture was quantified by qPCR. The range bars in the bar charts show the standard deviation of three biological replicates. Statistical differences in the abundance of MI at each time point between monoculture and coculture were analyzed by a Student t-test (*P < 0.005, **P < 0.01, and ***P < 0.001). Mono, monoculture; Co, coculture; BP, Bifidobacterium pseudocatenulatum_BWX; BL, Bifidobacterium longum_BWX; MI, Megasphaera indica_BWX.
