Fig. 6From: High-throughput optimization of medium components and culture conditions for the efficient production of a lipopeptide pseudofactin by Pseudomonas fluorescens BD5TOF-MS/MS spectra (top panel) of PF3 (a) and PF4 (b), with structure elucidation (middle panel). Ions at 1053 and 1067 m/z were used as precursors for analyses. Bottom panel: proposed structures of PF3 (a) and PF4 (b), based on Janek et al. [17]Back to article page
