英文摘要: Foaming problem and cost of substrate limit the commercial application of rhamnolipids, a potential biosurfactant produced by Pseudomonas aeruginosa . We explored the production of rhamnolipids by a semi-solid-state (SSS) fermentation strategy with glycerol as carbon source and rapeseed/wheat bran as matrix, along with the capacity of the produced rhamnolipids to solubilizelead and cadmium in aqueous solution. Structural analysis by MALDI-TOF MS indicated the increased proportion of mono-rhamnolipids from SSS fermentation. E24 results showed the stronger emulsification capacity and reduced water tension of the SSS fermentation product. Rhamnolipids from SSS fermentation can desorb lead/cadmium from contaminated soil effectively and heavy metals in exchangeable and carbonate forms were...
