Enzymatic biodiesel production has attracted tremendous interest due to its well-recognized advantages. However, high enzyme costs limit the application of enzymatic processes in industrial production. In past decade, great improvements have been achieved lab and scale, cost process reduced significantly, which led it being economically competitive compared chemical process. This paper summariz...
A flow-injection system was developed for the determination of ethanol with an immobilized enzyme-reactor column. This system, which consisted of hand-made reactor columns packed with alcohol oxidase and horseradish peroxidase immobilized onto chitosan beads, and a fluorometric detector, was applied to the determination of ethanol in liquor samples. Under the recommended conditions, the ethanol...
The ammonium-oxidizing microbial community was investigated in a granular sludge anaerobic ammonium-oxidizing (anammox) reactor that was operated for about 1 year with high anaerobic ammonium oxidation activity (up to 0.8 kg NH(4)(+)-N m(-3) day(-1)). A Planctomycetales-specific 16S rRNA gene library was constructed to analyse the diversity of the anaerobic ammonium-oxidizing bacteria (AnAOB). ...
The strongest fibrinolytic protease (F-III-2) in the six enzyme proteins purified from earthworm, Lumbricus rubellus [N. Nakajima et al., Biosci. Biotech. Biochem., 57, 1726-1730 (1993)] has been modified chemically with fragmented human serum albumin (mol. wt., 10,000-30,000). The modified enzyme lost the antigenicity of the native enzyme and reacted with the antisera against human serum album...
The rate of a reaction catalyzed by enzymes is influenced by various factors, including temperature, pH, chemical substances, etc.1 In this work, the influence of temperature on enzyme operational stability was studied. Temperature deactivation of an enzyme is usually defined as a transformation of an active enzyme into denaturated (deactivated) form, described by an irreversible first-order re...
