Recombinant strain qRT-PCR analysis, growth status, and AD conversion ratio of MNR, MNR-prpR and MNR-prpDBC. a qRT-PCR analysis of the expression variations of prpR, prpD, prpB and prpC. b Growth curves of MNR, MNR-prpR, and MNR-prpDBC. c Time courses of biotransformation rates of AD by MNR, MNR-prpR, and MNR-prpDBC. Error bars indicate the standard deviation from three independent experiments and the levels of statistical significance are indicated as follows: *p < 0.05; **p  < 0.01; ***p < 0.001; NS, indicates no significant difference (p > 0.05)
