Acidogenic fermentation of pretreated food waste under psychrophilic conditions for volatile fatty acids production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.

Rhamnolipid biosurfactant from Pseudomonas aeruginosa: From discovery to application in contemporary technology [PDF]

Journal of the Serbian Chemical Society, 2015
The rhamnolipids are most likely the next generation of biosurfactants which will reach the market. They should follow closely after alkyl polyglycosides, already established in the biosurfactants market, and sophorolipids, which can be found in

Heterologous production of long-chain rhamnolipids from Burkholderia glumae in Pseudomonas putida—a step forward to tailor-made rhamnolipids

, 2017
Rhamnolipids are biosurfactants consisting of rhamnose (Rha) molecules linked through a β-glycosidic bond to 3-hydroxyfatty acids with various chain lengths, and they have an enormous potential for various industrial applications.

Micellar and Solubilization Properties of Biological Surfactant Surfactin

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.

Influence of Calcium Ions on Rhamnolipid and Rhamnolipid/Anionic Surfactant Adsorption and Self-Assembly

Langmuir, 2013
The impact of Ca(2+) counterions on the adsorption at the air-water interface and self-assembly in aqueous solution of the rhamnolipid biosurfactant and its mixture with the anionic surfactant sodium dodecylbenzenesulfonate, LAS, has been studied using neutron reflectometry and small-angle neutron scattering. The results illustrate how rhamnolipids are
