Purpose of the research: to develop a laboratory prototype of amperometric biosensors on arginine based on recombinant enzymes (bacterial argininedeiminase and human liver arginase I) and the cells Hansenula polymorpha - over-producers of arginase; to test created biosensors on real samples of wines. As a result of the work performed in 2014: an arginine (L-Arg) selective enzymes (arginase and argininedeiminase) were obtained from the cells of recombinant yeast strains - over-producers of target enzymes and characterized. The laboratory prototypes of amperometric biosensors on L-Arg based on argininedeiminase, arginase and recombinant yeast cells with increased content of arginase were developed. An enzymatic method based on argininedeiminase on L-Arg with spectrophotometric mode of detection was developed and processed. The methods of L-Arg analysis were investigated on real samples of wines in comparison with referent chemical method. A strong correlation was shown to exist between the values obtained by the new and previously created methods. The developed methods based on arginine-hydrolizing enzymes was shown to possess the high validity during express-analyses of L-Arg levels in wines. According to the results of research 4 articles and 4 abstracts were published. Product Description popup.authors Іваш М.Ф. Борецький Ю.Р. Гайда Г.З. Гончар. М.В. Синенька М.М. Стасюк Н.Є.
