标题
The kinetically controlled synthesis of cephalexin in aqueous two-phase systems was studied, using immobilized penicillin acylase, 7-amino 3-desacetoxycephalosporanic acid as nucleophile and phenylglycine methyl ester as acyl donor. 出版机构：Elsevier Science 刊物名称：Process Biochemistry 出版时间：2010 ISSN：1359-5113 数据源：报刊文摘
The ability of a non-commercial immobilized Staphylococcus xylosus lipase to catalyze the esterification of propanol with gallic acid was investigated and the antioxidant as well as the antimicrobial activities of the ester formed were evaluated. 出版机构：Elsevier Science 刊物名称：Journal of Molecular Catalysis B: Enzymatic 出版时间：2010 ISSN：1381-1177 数据源：报刊文摘
?In situ removal of Cephalexin by SLMs with strip dispersion has been achieved. ? The maximum yield was increased from 32% to 42% with limited membrane area. ? The organic membrane solution did not significantly deactivate the liquid enzyme. ? 出版机构：Elsevier Science 刊物名称：Journal of Membrane Science 出版时间：2011 ISSN：0376-7388 数据源：报刊文摘
Herein we report the practical chemo enzymatic synthesis of trisaccharide and derivatives of iGb3 and Gb3, and a novel purification process using immobilized yeast to remove the monosaccharide from the reaction mixture. High purity oligosaccharide compounds were achieved in large scale. 出版机构：Elsevier Science 刊物名称：Bioorganic & Medicinal Chemistry Letters 出版时间：2011 ISSN：0960-894X 数据源：报刊文摘
For these reasons, great interest has arisen in carbohydrate-based pharmaceuticals and on the development of techniques for the analysis and synthesis of oligosaccharides. 出版机构：Informa Healthcare 刊物名称：Biocatalysis and Biotransformation 出版时间：2010 ISSN：1024-2422 数据源：报刊文摘
Hydrolysis of penicillin G and synthesis of amoxicillin from the 6-aminopenicillanic acid formed and d- p-hydroxyphenylglycine methyl ester were catalyzed in situ by a single enzyme. 出版机构：Springer Verlag 刊物名称：Applied Microbiology and Biotechnology 出版时间：2010 ISSN：0175-7598 数据源：报刊文摘
Mannosylerythritol lipids (MELs) produced by yeasts are one of the most promising glycolipid biosurfactants. In this study, we succeeded in the preparation of a novel MEL homolog having no acetyl groups, namely MEL-D. 出版机构：Elsevier Science 刊物名称：Carbohydrate Research 出版时间：2011 ISSN：0008-6215 数据源：报刊文摘
Comparative studies of enzymatic acylation of troxerutin by the alkaline protease from Bacillus subtilis under ultrasound and shaking were carried out in nonaqueous media. Using divinyl dicarboxylates (CH2 CH?OOC?(CH2) n ?COO? 出版机构：Elsevier Science 刊物名称：Ultrasonics Sonochemistry 出版时间：2011 ISSN：1350-4177 数据源：报刊文摘
Ethyl levulinate, produced through esterification of levulinic acid, is a ketoester with various applications. Synthesis of ethyl levulinate was carried out in solvent-free system using immobilized Candida antarctica lipase B (Novozym 435) as the biocatalyst for the reaction. 出版机构：Elsevier Science 刊物名称：Industrial Crops and Products 出版时间：2010 ISSN：0926-6690 数据源：报刊文摘
Theanine (?-glutamylethylamide) is the main amino acid component in green tea. The demand for theanine in the food and pharmaceutical industries continues to increase because of its special flavour and multiple physiological effects.
