Fig. 2From: Improvement of FK506 production via metabolic engineering-guided combinational strategies in Streptomyces tsukubaensisFK506 production and packed mycelium volume (PMV) in L19 and L19-2 at 168 h, respectively. Error bars showed standard deviations of three independent experiments. The asterisks indicated the statistic significant differences compared with L19, respectively. **P < 0.05; N, no significant differenceBack to article page
