Biosurfactant production by Pseudomonas aeruginosa BN10 cells entrapped in cryogels.

Production of a rhamnolipid biosurfactant by cells of Pseudomonas aeruginosa strain BN10 immobilized into poly(ethylene oxide) (PEO) and polyacrylamide (PAAm) cryogels was investigated under semicontinuous shake flask conditions and compared to biosurfactant secretion by free cells. The biosurfactant synthesis was followed over 9 cycles of operation of the immobilized system, each cycle compris...

Factorial Design to Optimize Biosurfactant Production by Yarrowia lipolytica

In order to improve biosurfactant production by Yarrowia lipolytica IMUFRJ 50682, a factorial design was carried out. A 2(4) full factorial design was used to investigate the effects of nitrogen sources (urea, ammonium sulfate, yeast extract, and peptone) on maximum variation of surface tension (Delta ST) and emulsification index (EI). The best results (67.7% of EI and 20.9 mN m(-1) of Delta ST...

PRODUCTION OF RHAMNOLIPID BIOSURFACTANT FROM A MARINE Pseudomonas aeruginosa

Biosurfactants are surface-active agents produced by hydrocarbanoclastic bacteria isolated from oil contaminated sites. In the present study a potential oil degrading bacterium was isolated from Cuddalore harbor waters and identified as Pseudomonas aeruginosa by using both biochemical and 16S rRNA sequencing. Growth optimization of the strain was done against varying physiochemical parameters v...

Hydrocarbon assimilation and biosurfactant production in Pseudomonas aeruginosa mutants.

We isolated transposon Tn5-GM-induced mutants of Pseudomonas aeruginosa PG201 that were unable to grow in minimal media containing hexadecane as a carbon source. Some of these mutants lacked extracellular rhamnolipids, as shown by measuring the surface and interfacial tensions of the cell culture supernatants. Furthermore, the concentrated culture media of the mutant strains were tested for the...

Production of biosurfactant using different hydrocarbons by Pseudomonas aeruginosa EBN-8 mutant.

The present investigation dealt with the use of previously isolated and studied gamma-ray mutant strain Pseudomonas aeruginosa EBN-8 for the production of biosurfactant by using different hydrocarbon substrates viz. n-hexadecane, paraffin oil and kerosene oil, provided in minimal medium, as the sole carbon and energy sources. The batch experiments were conducted in 250 mL Erlenmeyer flasks, con...
