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...
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 کاملStrategies for improved rhamnolipid production by Pseudomonas aeruginosa PA1
Rhamnolipids are biosurfactants with potential for diversified industrial and environmental uses. The present study evaluated three strategies for increasing the production of rhamnolipid-type biosurfactants produced by Pseudomonas aeruginosa strain PA1. The influence of pH, the addition of P. aeruginosa spent culture medium and the use of a fed-batch process were examined. The culture medium a...
متن کاملComparison between batch and fed-batch production of rhamnolipid by Pseudomonas aeruginosa
This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...
متن کاملBiosurfactant 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...
