One-step enzymatic production of fatty acid ethyl ester from high-acidity waste feedstocks in solvent-free media
(2011)
This work aims to demonstrate the enzymatic production of fatty acid ethyl ester biodiesel from highly acidic feedstock in a single-step reaction, without co-solvents and avoiding the inhibition of the enzyme
by ethanol ...
Hydrolysed Gelatin-Derived, Solvent-Free, Electrospun Nanofibres for Edible Applications: Physical, Chemical and Thermal Behaviour
(Food Biophysics, 2019-10-02)
Electrospinning is a novel technique which has been used recently in the food field. Electrospun nanofibres (NF) have often been produced from non-edible compounds. Biopolymer solutions were developed from gelatin hydrolysed ...

Immobilization of Eversa Lipases on Hydrophobic Supports for Ethanolysis of Sunflower Oil Solvent-Free
(2022-01-01)
Lipases are an important group of biocatalysts for many industrial applications. Two new commercial low-cost lipases Eversa® Transform and Eversa® Transform 2.0 was immobilized on four different hydrophobic supports: ...
Multiple effects of water on solvent-free enzymatic esterifications
(Elsevier Science Inc, 2007-07)
Enhancement of the catalytic activity of lipases has commonly been performed by biocatalyst modification (immobilization on hydrophobic supports, activatiFon with interfaces, pretreatment with amphiphiles, etc.). In this ...
Solvatochromism in Binary Mixtures: First Report on a Solvation Free Energy Relationship between Solvent Exchange Equilibrium Constants and the Properties of the Medium
(AMER CHEMICAL SOC, 2009)
We have employed UV-vis spectroscopy in order to investigate details of the solvation of six solvatochromic indicators, hereafter designated as ""probes"", namely, 2,6-diphenyl-4-(2,4,6-triphenylpyridinium-1-yl) phenolate ...
An insight on acyl migration in solvent-free ethanolysis of model triglycerides using Novozym 435
(Elsevier Science, 2016-01-12)
In this work, the ethanolysis of triglycerides catalyzed by immobilized lipase was studied, focusing on the secondary reaction of acyl migration. The catalytic tests were performed in a solvent-free reaction medium using ...
