چکیده

(S)-1-(2-Naphthyl)ethanol was yielded by immobilized pea (Pisum sativum L.) protein (IPP) from (R, S) 2-naphthyl ethanol (> 99% ee, yield; about 50%), in which the (R)-enantiomer was selectively oxidized to 2-acetonaphthone. IPP could be reused consecutively at least three times without any decrease of yield and optical purity.

Citronellyl Butyrate Synthesis in Non-Conventional Media Using Packed-Bed Immobilized Candida Rugosa Lipase Reactor

The synthesis of citronellyl butyrate by direct esterification reaction catalyzed by immobilized lipase from Candida rugosa was studied in a continuous packed bed reactor using n-hexane as organic solvent. Parameters such as residence time, temperature, and pH were examined. The optimum conversion was obtained at a flow rate of 1 ml/min (residence time 8 min), temperature of 50 °C, and pH 7.5. ...

Development of Clay Foam Ceramic as a Support for Fungi Immobilization to Biodiesel Production (RESEARCH NOTE)

Biodiesel is an attractive alternative fuel because of its nontoxicity and biodegradability properties. Biodiesel is produced through transesterification of vegetable oils’ triglyceride. It is obtained from vegetable oils or fats either by chemical or enzyme-catalyzed transesterification with methanol or ethanol. By using whole-cell biocatalyst immobilized within biomass support particles (BSPs...

Biomimetic synthesis of 1-aryl-2,5-dimethyl pyrroles using egg white nano-ovalbumin at room temperature under solvent-free conditions

Ovalbumin, as the major component of egg-white, is a globular, biocompatible, nontoxic and biodegradable phosphoglyco protein. This protein with the molecular weight of 44.5 kDa, contains 385 residues of amino acids with isoelectric point (pI) of 4.5. Many purification procedures have been reported for egg-white proteins such as gel permeation and anion exchange chromatography. In this study, w...
