Hydroperoxide-lyase activity in mint leaves. Volatile C6-aldehyde production from hydroperoxy-fatty acids.
The extraction of 13-hydroperoxide-lyase activity from mint leaves as well as its use for C6-aldehyde production was studied in this work. The enzyme cleaves 13(S)-hydroperoxy-C18 fatty acids intoExpand
Identification of an indigo precursor from leaves of Isatis tinctoria (Woad).
Indole is presumably a product of indole-3-glycerol phosphate catabolism in Isatis tinctoria. It is oxidized into indoxyl and stored in young leaves as indigo precursor. Further oxidation andExpand
Gas phase transesterification reactions catalyzed by lipolytic enzymes.
Porcine pancreatic lipase and Fusarium solani cutinase were used to catalyze transesterification reactions between methyl propionate, ethyl propionate, and a series of primary alcohols at highExpand
β‐Galactosidase Catalyzed Selective Galactosylation of Aromatic Compounds
A new approach to galacto‐oligosaccharides and galacto‐conjugates synthesis performed by the β‐galactosidase from Kluyveromyces lactisis reported. The enzymatic galactosylation of eight kinds ofExpand
β‐Glucosidase‐Catalyzed Hydrolysis of Indican from Leaves of Polygonum tinctorium
In this article, a HPLC method to identify and quantify the dyes and the indigo precursors produced in Polygonum tinctorium is described. Using this technique, indican has been positively identifiedExpand
Working at controlled water activity in a continuous process: The gas/solid system as a solution
Fusarium solani cutinase and Candida cylindracea lipase were used to catalyze a transesterification reaction in a continuous gas/solid bioreactor. In this system, a solid phase composed of a packedExpand
Phospholipid synthesis by extracellular phospholipase A2 in organic solvents.
The catalytic activity of extracellular phospholipase A2 was studied in low polarity solvents where hydrolytic enzymes have been demonstrated to catalyze synthesis reactions. It was demonstrated thatExpand
Alcoholysis catalyzed by Candida antarctica lipase B in a gas/solid system obeys a Ping Pong Bi Bi mechanism with competitive inhibition by the alcohol substrate and water.
The kinetics of alcoholysis of methyl propionate and n-propanol catalyzed by Candida antarctica lipase B supported onto silanized Chromosorb P was studied in a continuous solid/gas reactor. In thisExpand
Microwave-assisted synthesis of galacto-oligosaccharides from lactose with immobilized β-galactosidase from Kluyveromyces lactis
Galacto-oligosaccharides (GOS) were synthesized from lactose by immobilized and free β-galactosidase from Kluyveromyces lactis (Lactozym 3000 L HP-G) using either focused microwave irradiation orExpand
Stability improvement of immobilized Candida antarctica lipase B in an organic medium under microwave radiation.
The influence of microwave heating on the stability of immobilized Candida antarctica lipase B was studied at 100 degrees in an organic medium. The microwave radiation was carried out beforeExpand
