Synthesis of New Pentaerythritol-Based Gemini Surfactants
(Georg Thieme Verlag Kg, 2001-06)
New dimeric or gemini surfactants bearing double-chain with two or four sulfonate groups, and quadruple-chain with four sulfonate groups, were prepared from pentaerythritol in good overall yields. All these surfactants ...
Brønsted ionic liquids: study of physico-chemical properties and catalytic activity in aldol condensations
(2010)
A serie of substituted amines based ionic liquids was prepared using an aliphatic linear carboxylic acid (pentanoic acid). The ionic liquids synthesised are 2-hydroxy ethylammonium pentanoate (2-HEAPE),
2-hydroxy ...
Anti-Listeria monocytogenes activity of enterocins microencapsulated by ionic gelation
(Elsevier, 2012-10)
The encapsulation of enterocins synthesized by Enterococcus faecium CRL1385 through ionic gelation with calcium ions was analyzed. Different enterocins samples were lyophilised and encapsulated using low-methoxyl pectin ...
Insights into the effect of imidazolium-based ionic liquids on chemical structure and hydrolytic activity of microbial lipase
(2019-07-12)
This work studied the effect of the cation alkyl chain length of 1-alkyl-n-methylimidazolium chloride ([Cnmim]Cl)-based ILs on the activity of Aspergillus niger lipase. First, the lipase activity in the presence of different ...
Enhancing the Biocatalytic Activity of l -Asparaginase Using Aqueous Solutions of Cholinium-Based Ionic Liquids
(2019-12-16)
l-Asparaginase (ASNase) is a high value enzyme for the pharmaceutical and food industries. Although ionic liquids (ILs) have been recognized as promising solvents or additives for biocatalysis, there are very few studies ...
Effects of ph and ionic strength on the protease activity of gastric extracts from the coho salmon oncorhynchus kisutch
(Pontificia Universidad Católica de Valparaíso, 2019-11-07)
The activity of fish acid proteases is strongly dependent on the pH, and many basic and applied works had focused on researching the pH-profile of digestive proteases using different buffered media. Nevertheless, enzymatic ...
