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 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...
متن کاملProduction and Characterization of a Nitrilase from Pseudomonas aeruginosa RZ44 and its Potential for Nitrile Biotransformation
Background: The conversion of nitriles into amides or carboxylic acids by nitrilase has taken its application into consideration, as the scope of its applications has recently been extended. Objectives: In this study, P. aeruginosa RZ44 was isolated from sewage in the Kerman which has Nitrile-degradation activity. In order to improve the nitrilase production, several optimization were done on e...
متن کاملPseudomonas aeruginosa rhamnolipids disperse Bordetella bronchiseptica biofilms.
We have previously reported that the respiratory pathogen Bordetella bronchiseptica can form biofilms in vitro. In this report, we demonstrate the disruption of B. bronchiseptica biofilms by rhamnolipids secreted from Pseudomonas aeruginosa. This suggests that biosurfactants such as rhamnolipids may be utilized as antimicrobial agents for removing Bordetella biofilms.
