A kinetic framework is developed to describe enzyme activity and stability in two-phase liquid-liquid systems. In particular, the model is applied to the enzymatic production of benzaldehyde from mandelonitrile by Prunus amygdalus hydroxynitrile lyase (pa-Hnl) adsorbed at the diisopropyl ether

Pharmaceutical regulatory bodies require minimal presence of solvent in an active pharmaceutical ingredient (API) after crystallization. From a processing point of view bigger crystals with minimal agglomeration and uniform size distribution are preferred to avoid solvent inclusion and for improved

Tert-amyl-methyl ether (TAME) was administered by gavage in extra virgin olive oil solution at concentrations of 750, 250, or 0 mg/kg bw to groups of 100 male and 100 female Sprague-Dawley rats 8 weeks old at the start of the

Biotransformation of acrolein (ACR) was studied in vivo in the rat following inhalation and ip administration. The major and minor urinary metabolites were 3-hydroxypropylmercapturic acid (HPMA) and 2-carboxyethylmercapturic acid (CEMA), respectively. Male Wistar rats were exposed to ACR, 23, 42

A novel recycle reactor has been designed to determine the interfacial activity of hydroxynitrile lyase in a diisopropyl ether (DIPE)/water two-phase system. The reactor provides a known interfacial area. Enzyme activity toward mandelonitrile cleavage is continuously measured in the reactor
