Journal ArticleDOI

Optimization and characterization of biosurfactant production by Bacillus subtilis isolates towards microbial enhanced oil recovery applications

TL;DR: In this paper, three Bacillus subtilis strains (#309, #311 and #573) isolated from Brazilian crude oils were optimized based on different carbon and nitrogen sources, and the lowest surface tension values were obtained using sucrose containing media for the three isolates.
Journal ArticleDOI

Mixing ionic liquids – “simple mixtures” or “double salts”?

TL;DR: In the third issue of the then new journal Green Chemistry (2001, 3, 156-164), the physical properties of a few hydrophilic and hydrophobic ionic liquids (ILs) representing one of the first such studies was published.
Journal ArticleDOI

Ionic liquids as adjuvants for the tailored extraction of biomolecules in aqueous biphasic systems

TL;DR: The results obtained indicate that the addition of small amounts of IL to the typical PEG/inorganic salt aqueous systems could largely control the extraction efficiency for L-tryptophan, and that efficiency depends on the IL employed.
Journal ArticleDOI

Isolation and study of microorganisms from oil samples for application in Microbial Enhanced Oil Recovery

TL;DR: In this paper, the isolation and identification of microorganisms capable of producing biosurfactants and promote degradation of long-chain n-alkanes under conditions existent in oil reservoirs were addressed.
Journal ArticleDOI

Insight into the Interactions That Control the Phase Behaviour of New Aqueous Biphasic Systems Composed of Polyethylene Glycol Polymers and Ionic Liquids

TL;DR: It was observed that contrary to typical ABS based on ionic liquids and inorganic salts, the phase behaviour is dominated by the formation of the hydration complexes of the ions, the interactions between the PEG polymers and Ionic liquids control the phase demixing in the polymer-type ABS studied herein.
