Fig. 3From: Improvement of FK506 production via metabolic engineering-guided combinational strategies in Streptomyces tsukubaensisAnalysis of metabolite profiles in L19 and L19-2 by full wavelength scanning. Equal volume of fermentation broths from different strains was harvested, ultrasonically extracted with 2.5-fold volume of methanol and then subjected to HPLC analysis. The wavelength scanned from 190 to 600Â nmBack to article page
