摘要

Rhamnolipids (RLs) are anionic biosurfactants with great application potential. This study explored the possibility of producing RLs from cooking oil fume condensates (COFCs) collected from range hoods. A mutant of Pseudomonas aeruginosa AB93066 was obtained and used to produce RLs from COFCs as a substrate. RL yields in a 7-L fermenter reached 12.3g/L, and MALDI-TOF MS showed that Rha(2)-C-10-C-10 and Rha-C-10-C-10 are the most abundant (39.6% and 26.4%, respectively) RL components. The critical micellar concentration (CMC) of the RLs was 45.0mg/L and the surface tension of water decreased from 60.5 to 25.3 mN/m. Using six kinds of common hydrocarbons as indices, the emulsification coefficients of the RLs obtained were found to exceed 60%; in particular, the emulsification coefficient for benzene was 80.3%. COFCs provide an inexpensive alternative as a substrate for RL production, and the synthetic process is relatively harmless and economical.
