Effect of different Hyds knockout on the metabolic characteristics in C. tyrobutyricum. A Metabolic characteristics of different Hyd deficient strains under CGM culture conditions without CaCO3 as a pH buffer. B The relative transcriptional levels of hydA, hyd1 and hyd2 on the different strains. The values represent the averages of three replicates and the error bars represent the standard errors of these experiments (*p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001, t test)
