Abstract:
... Lipases from ten different sources and two mycelium-bound lipases isolated from Amazonian fungi were screened as biocatalysts in the acylation reaction of d-ribono-1,4-lactone with a variety of acyl donors in non-aqueous media. Several reaction parameters were evaluated including the type and amount of enzyme, acyl donor, and organic solvent, as well as the influence of water and the recyclability ...

Abstract:
... Enzymatic synthesis of aromatic esters of four different sugar alcohols (xylitol, arabitol, mannitol, and sorbitol) with 3-(4-hydroxyphenyl)propionic acid was performed in organic solvent medium, using immobilized Candida antarctica lipase (Novozyme 435), and molecular sieves for control of the water content. The influence of reaction parameters on the conversion has been investigated, including r ...

Abstract:
... Ferulic acid acylation of oligosaccharides catalyzed by feruloyl esterases (FAE) is a promising route to produce feruloylated oligosaccharides. However, modulation of FAE synthetic properties is a key step to improve the acylation. The efficiency of H. insolens FAE to catalyze the feruloylation in six different surfactantless microemulsions reaction systems was evaluated. The highest yield (57%) w ...
