The present study describes the production of biosurfactant from isolate B. licheniformis Ali5. Seven different, previously-reported minimal media were screened for biosurfactant production, and two selected media were further optimized for carbon source. Further, various fermentation conditions such as (pH 2–12, temperature 20–50 °C, agitation speed 100–300 rpm, NaCl (0–30 g·L−1) were investigated. The partially purified biosurfactant was characterized by Fourier transform infrared spectroscopy (FTIR) and matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF MS) and found a lipopeptide mixture, similar to lichenysin-A. Biosurfactant reduced surface tension from 72.0 to 26.21 ± 0.3 and interfacial tension by 0.26 ± 0.1 mN·m−1 respectively, biosurfactant yield under optimized conditions was 1 g·L−1, with critical micelle concentration (CMC) of 21 mg·L−1 with high emulsification activity of (E24) 66.4 ± 1.4% against crude oil. Biosurfactant was found to be stable over extreme conditions. It also altered the wettability of hydrophobic surface by changing the contact angle from 49.76° to 16.97°. Biosurfactant efficiently removed (70-79%) motor oil from sand, with an efficiency of more than 2 fold as compared without biosurfactant (36–38%). It gave 32% additional oil recovery over residual oil saturation upon application to a sand-packed column. These results are indicative of potential application of biosurfactant in wettability alteration and ex-situ microbial enhanced oil recovery.

“…Sites that are contaminated with oil and/or its derivatives carry a good source of biosurfactant producers, since these pollutants stimulate their metabolism and growth (Alvarez et al 2015). Thus, for rhamnolipid production, a strain of Pseudomonas aeruginosa was used, which was selected and isolated from a soil artificially contaminated with a solution of crude oil in diesel of 2.50 g/L and moistened with the mineral medium described by Robert et al (1989).…”

“…This mechanism uses microorganisms, whether indigenous or exogenous, in the production of metabolites to increase oil recovery (Passman et al 2013;Armstrong et al 2015;Le et al 2015;Jahanbani Veshareh et al 2018). The metabolites that can be used as surface agents (amphiphilic molecules), biosurfactants, are promising substances in the substitution of chemical surfactants and they can increase the lifespan of mature reservoirs (Sen 2008;Banat et al 2010;Alvarez et al 2015).…”

In this study, the biosurfactant produced by Pseudomonas aeruginosa was evaluated in view of its ability to be used in Microbial-Enhanced Oil Recovery (MEOR). This microorganism was isolated from a soil artificially contaminated with crude oil and used to produce rhamnolipid using glycerol as the carbon source. The biosurfactant efficiently reduced water surface tension from 72 to 35.26 mN/m at its critical micelle concentration of 127 mg/L and emulsification rate (E 24) of 69% for the crude oil. Furthermore, it was demonstrated that the rhamnolipid can recover oil, even 2 months after its production, which shows that its biodegradability is not a disadvantage to the application in MEOR. The best result, for a biosurfactant concentration of 100% above the Critical Micelle Concentration (CMC) and petroleum with API gravity of 21.90, showed that the total recovery factor was 50.45 ± 0.79%, of which 11.91 ± 0.39% corresponds to MEOR.

“…Therefore, these results are very promising by characterizing the biosurfactant of C. glabrata as an excellent emulsifier once Alvarez et al (2015) consider emulsifying agents those that are capable to form emulsions by Emulsification Index (IE 24) values above 50%.…”

The world market for biosurfactants has grown gradually. However, the lack of competitiveness with chemical surfactants due to high cost of production remains a concern. Considering the need to reduce the costs of production, the aim of this work was to study the production and structural characterization of a biosurfactant produced by a strain of yeast Candida glabrata UCP 1556. The lowcost medium containing agro-industrial wastes whey 40% (v/v) and 20% (v/v) corn steep liquor were used as substrates in submerged fermentation. Biosurfactant production was detected by surface tension, oil displacement test and Critical Micelle Concentration (CMC). The structural characterization was performed by Fourier transform infrared (FT-IR), gas chromatography-mass spectrometry (GC-MS) and ionic profile. The stability of emulsions and potential in reducing the viscosity also were investigated. The results showed that the biosurfactant reduced the surface tension to 28.8 mN/m with CMC of 2% and showed anionic profile. Additionally, the biosurfactant formed stable emulsions at temperature (0 to 120°C), pH (2 to 12) and NaCl (2 to 12%), reduced the viscosity of soybean oil (
