“…In both spectra it is possible to observe bands characteristic of peptides (wavelength 3430 NH, wavelength 1655 CO, and wavelength 1534 CN) and aliphatic chains (wavelength 3000-2800), indicating that this compound is a lipopeptide. Similar results were obtained by other authors [38] with B. subtilis and [39] when determining the chemical structure of the surfactant produced by B. licheniformis. No significant difference in IR spectra of the biosurfactant produced in this work and the standard sample is observed.…”

In this study, the bacterium Bacillus licheniformis has been isolated from oil reservoir; the ability of this bacterium to produce a biosurfactant was detected. Surface properties of the produced biosurfactant were confirmed by determining the emulsification power as well as surface and interfacial tension. The crude biosurfactant has been extracted from supernatant culture growth, and the yield of crude biosurfactant was about 1 g/l. Also, chemical structure of the produced biosurfactant was confirmed using FTIR analysis. Results revealed that, the emulsification power has been increased up to 96% and the surface tension decreased from 72 of distilled water to 36 mN/m after 72 h of incubation. The potential application of this bacterial species in microbial-enhanced oil recovery (MEOR) was investigated. The percent of oil recovery was 16.6% upon application in a sand pack column designed to stimulate an oil recovery. It also showed antimicrobial activity against the growth of different strains of SRB (sulfate reducing bacteria). Results revealed that a complete inhibition of SRB growth using 1.0% crude biosurfactant is achieved after 3 h. ª 2015 Production and hosting by Elsevier B.V. on behalf of Egyptian Petroleum Research Institute.

“…Following centrifugation, the precipitate was dissolved in distilled water and adjusted to pH 7.0 using 1N NaOH, then recentrifuged at 12,000 × g for 10 min. The solution was lyophilized and weighed [25][26][27].…”

“…These biosurfactants were composed of protein and lipids. Biosurfactants composed of lipid and proteins have been reported by different groups (Nakano and Zuber, 1989;Rosenberg, 1986;IVex et al, 1990;Mulligan et al, 1989;Fiechter, 1992;Lin et al, 1994). Pseudomonas putida, P. -diminuta and P. aeruginosa biosurfactant isolates had 6%, 4% and 8% protein -while the lipid content was 45%, 42% and 48% respectively.…”

The appearance of surface active compounds in the culture broths grown on hydrocarbons can be easily monitored by measuring the surface tension of the cell free broth. Using three bacterial strains it was found that yields of the biosurfactants were maximum at the time when lowest surface tension values were recorded. Thus reduction of surface tension of the medium is a rapid method for assay of maximum biosurfactant formation prior to their actual isolation.
