Partial Characterization of Biosurfactant from Lactobacillus pentosus and Comparison with Sodium Dodecyl Sulphate for the Bioremediation of Hydrocarbon Contaminated Soil

Table 3

Comparison of relative emulsion volume (EV) and stability (ES) after 24 h, of octane/water emulsions formed and stabilized with the biosurfactant produced by L. pentosus during fermentation of sugars in vineyard pruning waste and sodium dodecyl sulfate (SDS). Data are compared with EV and ES values reported for gasoline or kerosene and surfactin, SDS or biosurfactants produced by L. pentosus.

Hydrocarbon	EV (%)	ES (%)	Surfactant	Reference
Gasoline	38.9–45.5	85.0–94.7	Biosurfactant produced by L. pentosus with lignocellulosic residues as substrate	[16]
Gasoline	22.3	64.6	Surfactin produced by Bacillus subtilis	[16]
Gasoline	66.2	96.1	SDS	[16]
Kerosene	21.7–49.0	84.9–99.0	Biosurfactant produced by L. pentosus with lignocellulosic residues as substrate	[16]
Kerosene	30.4	73.1	Surfactin produced by Bacillus subtilis	[16]
Kerosene	62.3	87.7	SDS	[16]
Octane	39.8	85.7	Biosurfactant produced by L. pentosus using hemicellulosic sugars that could be obtained from trimming vineyard.	Present study
Octane	64.0	94.0	SDS	Present study
