Fig. 3From: Regulation of CcpA on the growth and organic acid production characteristics of ruminal Streptococcus bovis at different pHRelative mRNA expressions of α-amy, ldh, ack and pfl in wild-type strain (wt) and ccpA-knockout strain (ko) of S.bovis S1 at different pH. Values are the means (n = 3), with standard deviation indicated by vertical bars. α-amy, α-amylase; ldh, lactate dehydrogenase; ack, acetokinase; pfl, pyruvate formate lyaseBack to article page
