Fig. 4From: Rational construction of genome-reduced and high-efficient industrial Streptomyces chassis based on multiple comparative genomic approachesMetabolite profiles analysis based on iso-absorbance plot. S. chattanoogensis L10 (down) and L321 (up) are inoculated about 120 h in different fermentation media, YSG (a), YEME (b) and ISP2 (c). The methanol extract of fermentation broth is analyzed by HPLC with wavelength scanning from 190 nm to 600 nm. x axis represents HPLC time (min) and y axis represents absorption wavelength (nm)Back to article page
