PRODUCTION OF RHAMNOLIPIDS-PRODUCING ENZYMES OF PSEUDOMONAS IN E. COLI AND STRUCTURAL CHARACTERIZATION

摘要

Rhamnolipids have a great potential to be utilized in industries due to their surface active properties and non-toxic impact on the enviroment. Accumulated studies have shown that the major producer of rhamnolipids is Pseudomonas aeruginosa (P. aeruginosa) which is a pathogenic strain. Despite efforts spent to improve rhamnolipid yield by screening different organisms, optimizing fermentation conditions, and optimizing strains through metabolic engineering, the cost for rhamnolipid production is still very high compared with chemically synthesized surfactants. Therefore, it is necessary to explore an alternative strategy for rhamnolipids production.
