Microbial Enhanced Oil Recovery Using Biosurfactant Produced by Alcaligenes faecalis
A bacterial strain (designated as Alcaligenes sp. MS-103) isolated from oil sample of the Aghajari oilfield in the south of Iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. The highest surface tension reduction to level 20 mN/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...

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 کاملPRODUCTION 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 کاملApplication of extracellular lipopeptide biosurfactant produced by endophytic Bacillus subtilis K1 isolated from aerial roots of banyan (Ficus benghalensis) in microbially enhanced oil recovery (MEOR)
Bacillus subtilis K1 isolated from aerial roots of banyan tree secreted mixture of surfactins, iturins and fengycins with high degree of heterogeneity. The extracellular extract consisting of mixture of these cyclic lipopeptides exhibited very good emulsification activity as well as excellent emulsion stability. The culture accumulated maximum surfactant up to 48 h of growth during batch fermen...
