Abstract
Compositions are provided for hydrocarbon separation applications. In some embodiments, the composition comprises lignin, in particular technical lignin, and at least one strain of bacteria capable of biosurfactant production and/or a biosurfactant produced by at least one such isolated strain of bacteria. Also provided is a method for separating hydrocarbons from a hydrocarbon-containing material.
Claims22
A method for separating hydrocarbons from a hydrocarbon-containing material, the method comprising:
- providing a composition comprising lignin, and at least one isolated strain of bacteria capable of producing at least one biosurfactant, and/or at least one biosurfactant produced from at least one bacteria capable of producing a biosurfactant, the composition having a solids content of about 50% or above;
- and
- contacting the hydrocarbon-containing material with the composition, thereby to separate out at least a portion of the hydrocarbons from the hydrocarbon-containing material.
The composition of claim 20, wherein the carboxylic acid ester comprises a methyl ester or a butyl ester or wherein the carboxylic acid or salt or ester thereof comprises a di-carboxylic acid or a salt or ester thereof.
