Abstract

EL ACIDO AMINO ACETILENICO N SE OBTIENE EN UN REACTOR PARTIENDO DE ACETILGLUCOSAMINA N, QUE CONTIENE TANTO ACETILGLUCOSAMINA GLCNAC EN MANNAC COMO TAMBIEN EL ACETILGLUCOSACIDO MANNAC FORMADO CON ACIDO PIRUVICO Y ALIMENTADO EN EL GLCNAC Y PYR Y EN CUYO DESARROLLO SE OBTIENE NEU5AC. PREFERENTEMENTE SE TRABAJA EN CONTINUO Y EN PARTICULAR EN EL REACTOR DE MEMBRANA DE ENCIMAS PARA UN PH 7,5 Y 25 C, QUE EVENTUALMENTE SE DOSIFICA. EL EPIMERASO Y LA LISINA SE ENCUENTRAN PREFERENTEMENTE EN EL REACTOR EN UNA PROPORCION DE ACTIVIDAD, PARA LA QUE EL VALOR RECIPROCO DEL COCIENTE CORRESPONDE AL DE LAS VELOCIDADES DE TRANSFORMACION.
