“…Nowadays, extensive research have been conducted on the isolation and characterization of novel surfactant-producing microbes and their use in ecological remediation (Yan et al 2012). Biosurfactants are classified based on their chemical configuration as glycolipids, lipopeptides, lipopolysaccharides, or oligosaccharides and are produced by diverse bacterial genera (Franzetti et al 2010).…”

Among 348 microbial strains isolated from petroleum hydrocarbon-contaminated soil, five were selected for their ability to produce biosurfactant based on battery of screening assay including hemolytic activity, surface tension reduction, drop collapse assay, emulsification activity, and cell surface hydrophobicity studies. Of these, bacterial isolate DSVP20 was identified as Pseudomonas aeruginosa (NCBI GenBank accession no. GQ865644) based on biochemical characterization and the 16S rDNA analysis, and it was found to be a potential candidate for biosurfactant production. Maximum biosurfactant production recorded by P. aeruginosa DSVP20 was 6.7 g/l after 72 h at 150 rpm and at a temperature of 30 °C. Chromatographic analysis and high-performance liquid chromatography-mass spectrometry (HPLC-MS) revealed that it was a glycolipid in nature which was further confirmed by nuclear magnetic resonance (NMR) spectroscopy. Bioremediation studies using purified biosurfactant showed that P. aeruginosa DSVP20 has the ability to degrade eicosane (97%), pristane (75%), and fluoranthene (47%) when studied at different time intervals for a total of 7 days. The results of this study showed that the P. aeruginosa DSVP20 and/or biosurfactant produced by this isolate have the potential role in bioremediation of petroleum hydrocarbon-contaminated soil.

“…The design of a bioremediation technology requires finding a biocatalyst (microorganism) possessing sufficient biodegradation activity and often also a method of increasing the bioavailability of hydrophobic pollutants for this selected microorganism. Culture conditions and the physiological state of cell populations can also significantly affect the ability to utilize contaminating pollutants [11,12]. The use of biosurfactants in environmental applications has been quite promising because of their biodegradability, both in water and in the soil.…”

Abstract:In this study, the authors have investigated the potential of a bacterial strain of Pantoea sp., isolated from wastewater of the textile industry, for the production of biosurfactant. The biosurfactant production was optimized by the combination of CCD (central composite design) and RSM (response surface methodology). To assess the effects and interactions of medium the vegetable fat (1.5, 2.0 and 2.5 v/v), the variables corn steep liquor (2.0, 5.0 and 8.0 v/v) and pineapple peel residue (10.0, 25.0 and 40.0 v/v) on the surface tension were evaluated. The empirical model developed through RSM in terms of the effective operational factors mentioned above was found to be adequate to describe the biosurfactant production. Compositional analysis of the produced biosurfactant has been carried out by FT-IR (Fourier transform infrared spectoscopy) and subjected to the test of removing hydrocarbons. Through the analysis, vegetable fat and pineapple peel residue were found to be the most significant factors, whereas corn steep liquor had less effect within the ranges investigated. A maximum reduction in surface tension of 30.00 mN/m was obtained under the optimal conditions of 2.0% (v/v) vegetable fat concentration, 5.0% (v/v) corn steep liquor and 25.0% (v/v) pineapple peel residue concentration of medium. FT-IR spectrometer analysis of the biosurfactant characterized it as a glycolipid derivative. The biosurfactant exhibited the ability to solubilize the hydrocarbons tested, working between 64% and 92%. According to consists of bars with a length proportional to the absolute value of the estimated effects divided by the standard error. On this chart, ANOVA (analysis of variance) effect estimates are arranged from the largest to smallest absolute value. The chart includes a vertical line at the critical p-value of 0.05. Effects for which the bars are smaller than the critical p-value are considered non-significant and do not have an effect on the response variables. The effects are either positive or negative ANOVA; the determination of regression coefficients and the construction of graphs were performed using the Statistical ® program, version 7.0 (Statsoft Inc, RSA). The results, the biosurfactant produced by Pantoea sp. can be a valuable source for application in rapid environmental bioremediation.
