报告摘要:

Rhamnolipids are arguably the most promising biosurfactants for various large-scale industrial, environmental and agricultural applications, particularly for certified “organics” products. Rhamnolipids are produced by some bacteria for metabolic and physiological purposes. In fermentation, overproduction takes place in the stationary phase but is complicated by low conversion and highly foaming nature in aerobic fermentation. Prof. Ju’s group has improved the techniques for selecting high yield and productivity strains. They have also pioneered the new denitrification-based production route, to avoid foaming or oxygen-limiting issues (such as for in-situ rhamnolipid production in soil). Besides production and downstream collection, Ju’s group has explored various applications of rhamnolipids such as their antimicrobial and antifouling activities, fungal morphology modification, affinity foaming for enzyme purification, soil adsorption, and use as agricultural biopesticide. They have also chemically converted rhamnolipids to some chemicals and polymers. An overview will be given as the framework to encourage communication and collaboration.
