Biosurfactants are structurally diverse and heterogeneous groups of surface-active amphipathic molecules. Owing to their capability to reduce surface and interfacial tension, they have a wide range of industrial and environmental applications. The present chapter reviews the most recent results obtained in the production technologies, optimization ...

Application of Biosurfactant in Petroleum
2023As demonstrated by the invasion of Ukraine by Russia in 2022, crude oil is crucial for our society, and geopolitical instabilities, which cause uncertainties about petroleum production and distribution, have a significant impact in the price of crude oil and, consequently, in our daily life.

Emulsion Polymerization with a Biosurfactant
Langmuir, 2017Emulsion polymerization of styrene was conducted using a biosurfactant (i.e., sodium surfactin, hereinafter called just "surfactin") having very low critical micelle concentration (CMC, 2.9 × 10-3 mmol/L) and biodegradability characteristics. The nucleation mechanism was investigated by comparing with a conventional surfactant (i.e., sodium dodecyl ...

Biosurfactants produced by different types of microorganisms are amphiphilic biomolecules with active surface properties. Recently, biosurfactants have emerged as promising agents for cancer therapy since a high diversity of these molecules has shown the ability to induce cytotoxicity against many cancer cell lines, thus regulating cancer progression ...

Biosurfactants in cosmetics and biopharmaceuticals
Letters in Applied Microbiology, 2015Biosurfactants are surface-active biomolecules that are produced by various micro-organisms. They show unique properties i.e. lower toxicity, higher biodegradability and environmental compatibility compared to their chemical counterparts. Glycolipids and lipopeptides have prompted application in biotechnology and cosmetics due to their multi-functional

Production of rhamnolipid biosurfactants
1995Biosurfactants are of increasing interest due to their broad range of potential applications. A large variety of microbial surfactants is known at present, some of which may be used for specific applications. Towards the large scale industrial production of biosurfactants, the physiology, biochemistry and genetics of biosurfactant synthesis has to be ...

Recovery of biosurfactants by ultrafiltration
Journal of Chemical Technology & Biotechnology, 1990AbstractUltrafiltration was used in a one‐step method to purify and concentrate biosurfactants—surfactin and rhamnolipids—from culture supernatant fluids. The ability of surfactant molecules to form micelles at concentrations above the critical micelle concentration allows these aggregates to be retained by relatively high molecular weight cut‐off ...

Biosurfactants and oil bioremediation
Current Opinion in Biotechnology, 2002Oil pollution is an environmental problem of increasing importance. Hydrocarbon-degrading microorganisms, adapted to grow and thrive in oil-containing environments, have an important role in the biological treatment of this pollution. One of the limiting factors in this process is the bioavailability of many fractions of the oil.
