Fig. 4From: Variants of lipopeptides and glycolipids produced by Bacillus amyloliquefaciens and Pseudomonas aeruginosa cultured in different carbon substratesComparison of the extracts obtained from ST5 cultivated in mineral salt medium supplemented with a water immiscible substrates and b water miscible substrates, showing the relative contribution of each of the rhamnolipid groups in the biosurfactant extracts. The contribution was calculated from UPLC profiles, with the assumption that all the rhamnolipid species have similar ion responseBack to article page
