“…When pH was adjusted to 2, 4 and 6, surface tension reduction values of biosurfactant were 32.0, 31.9 and 31.6 mN/m and the corresponding emulsification values were 54.6, 60.3 and 64.8%, respectively. At low pH, the values of emulsification activity and surface tension were decreased due to biosurfactant precipitation, which hinders the formation of double layers and the micelles become less negative charge (Sakthipriya et al, 2015). The optimum surface tension reduction value (30.1 mN/ m) and emulsification index (73%) was observed at pH 7.…”

“…Following incubation, cultures were centrifuged at 9000 rpm for 10 min, and the cell-free supernatant was used to test biosurfactant activity (Belgacem et al, 2015). Pseudomonas aeruginosa ATCC 27853, which has previously been described as a biosurfactant producer, was used as the positive control (Sakthipriya et al, 2015).…”

SummaryBiosurfactant‐producing bacteria were isolated from samples collected in areas contaminated with crude oil. The isolates were screened for biosurfactant production using qualitative drop‐collapse test, oil‐spreading and emulsification assays, and measurement of their tensoactive properties. Five isolates tested positive for in the screening experiments and displayed decrease in the surface tension below 30 mN m−1. The biosurfactants produced by these isolates were further investigated and their molecular identification revealed that they are bacteria related to the Bacillus genus. Additionally, the biosurfactants produced were chemically characterized via UHPLC‐HRMS experiments, indicating the production of surfactin homologues, including a new class of these molecules.

“…A strain of Pseudomonas aeruginosa B031, which was isolated from the rhizosphere of Paraserianthes falcataria L. Nielsen, probably has unique characters, as shown by Thavasi et al (2011) and Sakthipriya et al (2015), especially in terms of biosurfactant production. In this regard, it is impor tant to investig ate the medium compositions involving variations in carbon sources (n-hexadecane, glycerol, and glucose) and nitrogen sources (urea, NH Cl and NaNO ) for 4 3 the production of biosurfactants by Pseudomonas aeruginosa B031.…”

The biosurfactants are used by several industrial sectors such as petroleum, agriculture, food production, chemistry, cosmetics, and pharmaceuticals. Because of their hydrophobic and hydrophilic moieties, they have potency to reduce surface tension, interfacial tension between water-hydrocarbon systems, and low micelle concentration. Their characteristics strongly depend on the producer strain as well as on the medium composition, such as carbon and nitrogen sources. This study was conducted to investigate the influence of different sources of carbon (n-hexadecane, glycerol and glucose) and nitrogen (urea, NH Cl and NaNO ) for the production of biosurfactants by a new strain of 4 3Pseudomonas aeruginosa B031 isolated from a rhizosphere of Paraserianthes falcataria L. Nielsen, a hardwood plant species at a phytoremediation field. The biosurfactant characteristics of the strain were evaluated, particularly its surface-active properties and potential to remove hydrocarbon. Glycerol was found to be the optimum carbon source, with rhamnose concentration, emulsification index, and critical micelle concentration (CMC) of 718 mg/L, 37%, and 35 mN/m, respectively. Sodium nitrate (NaNO ) was observed as the optimum nitrogen source, with rhamnose 3 concentration, emulsification index, and CMC of 290 mg/L, 30%, and 24 mN/m, respectively. These biosurfactants efficiently reduced surface tension of culture broth from 42 mN/m to 31 mN/m for the glycerol treatment and from 37 mN/m to 24 mN/m for the sodium nitrate treatment. The crude biosurfactants from the glycerol and sodium nitrate treatments also removed 87.5% and 84%, respectively, of crude oil from sand. These rates were higher than those of the chemical surfactants (SDS and Triton X-100). These findings indicate that the biosurfactants produced by the strain from both glycerol and NaNO treatments can efficiently decrease the interfacial tension of culture broth 3 dilution and have a high emulsion index, thus hold promise in hydrocarbon bioremediation application.
