Improved Production of Rhamnolipids by a Pseudomonas aeruginosa Mutant
A Pseudomonas aeruginosa mutant derived by random mutagenesis with N-methyl-N¢-nitro-N-nitrosoguanidine, producing high levels of the rhamnolipid biosurfactants was selected on Siegmund-Wagner (SW) plates. The mutant designated P. aeruginosa PTCC1637 produces rhamnolipids at concentrations 10 time more than parent strain. NMR analysis and surface tension measurement showed that the biosurfactan...
متن کاملBiodiesel Production From Rapeseed Oil With Waste Frying Oils
Biodiesel or fatty acids alkyl esters (FAAE) of long chain are an alternative fuel produced by a transesterification process. The potential production of biodiesel from rapeseed oil in Chile is associated to the solution of economic, environmental and social problems. Experiences from other countries have demonstrated that biodiesel prices are higher than diesel, due to the high costs of the ra...
متن کاملOptimization of rhamnolipid production by Pseudomonas aeruginosa OG1 using waste frying oil and chicken feather peptone
In the present study, production of rhamnolipid biosurfactant by Pseudomonas aeruginosa OG1 was statistically optimized by response surface methodology. Box-Behnken design was applied to determine the optimal concentrations of 52, 9.2, and 4.5 g/L for carbon source (waste frying oil), nitrogen source (chicken feather peptone), and KH2PO4, respectively, in production medium. Under the optimized ...

متن کاملOxygen effects on rhamnolipids production by Pseudomonas aeruginosa
BACKGROUND Rhamnolipids are the most extensively studied biosurfactants and has been successfully used in various areas from bioremediation to industrial fields. Rhamnolipids structural composition decide their physicochemical properties. Different physicochemical properties influence their application potential. Rhamnolipids can be produced at both aerobic conditions and anaerobic conditions b...
