Abstract:

Rhamnolipid(RL) was a kind of glycosolipid biosurfactant synthesized by microorganism with excellent surface activity, physical and chemical properties, and broad application prospect. Pseudomonas aeruginosa was the main strain for RL production, which could produce RL by fermentation with a variety of water-soluble carbon sources or hydrophobic carbon sources as substrates. At present, waste and pollution caused by waste carbon resources(WCR) were increasingly serious, based on the characteristics of RL and the substrate preference of producing strain, the production of RL from waste carbon resources had great development potential. In this paper, the research progress of RL production using waste oils(ioly wastewater, food processing waste oil and kitchen waste iol), sugary waste(sugar-containing food processing by-products, sugar-containing fruit and vegetable waste and lignocellulose) and waste plastics was introduced. The effects of different substrates and producing strains for RL yield were mainly highlighted. By analyzing the current status of WCR utilization, it was found that various species, low classification degree, and unbiodegradable ingredients were the main factors restricting the further development of RL production using WCR as substrates, and the future development direction of RL production based on WCR was also pointed out.

Key words: rhamnolipid, waste carbon resources, Pseudomonas aeruginosa, fermentation
