Enhancement of Pseudomonas Aeruginosa Growth and Rhamnolipid Production Using Iron-Silica Nanoparticles in Low-Cost Medium
The application of iron-silica (Fe-Si) nanoparticles for the enhancement of the Pseudomonas aeruginosa growth and rhamnolipid production in molasses medium was studied. The experiments were designed based on the response surface method (RSM) to optimize growth and rhamnolipid production. The concentration of nanoparticles and the time required to add nanoparticles to culture medium were conside...
متن کاملPseudomonas Rhamnolipid Surfactant (Biosurfactant)
A microbial surfactant (biosurfactant) was investigated for its potential to enhance bioavailability and, hence, the biodegradation of octadecane. The rhamnolipid biosurfactant used in this study was extracted from culture supernatants after growth of Pseudomonas aeruginosa ATCC 9027 in phosphate-limited proteose peptone-glucose-ammonium salts medium. Dispersion of octadecane in aqueous solutio...
متن کاملRhamnolipid surfactant production affects biofilm architecture in Pseudomonas aeruginosa PAO1.
In response to certain environmental signals, bacteria will differentiate from an independent free-living mode of growth and take up an interdependent surface-attached existence. These surface-attached microbial communities are known as biofilms. In flowing systems where nutrients are available, biofilms can develop into elaborate three-dimensional structures. The development of biofilm archite...
متن کاملRhamnolipid Biosurfactants Produced by Pseudomonas Species
Surfactants are chemical products widely used in our daily life in toothpaste and other personal hygiene and cosmetic products, and in several industries. Biosurfactants are surfactants of biological origin that can be produced by microorganisms and have many advantages, such as low toxicity and high biodegradability, compared to synthetic counterparts. Unfortunately, high production costs limi...
متن کاملChemical structures and biological activities of rhamnolipid biosurfactants produced by Pseudomonas aeruginosa M14808
P. aeruginosa M14808 was screened to produce rhamnolipid with high yield by mutation in a high magneto-gravitational environment. After silica gel columniation chromatogram, the components of the crude biosurfactant extract were analyzed by TLC, FTIR, and ESI-MS. The major components were characterized as rhamnolipids. The rhamnolipids consisted of two main types, monoand di-rhamnolipids. Di-rh...
