Abstract

METODO PARA PRODUCIR NUCLEOSIDOS DEL TIPO DE INOSINA O GUANOSINA.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UN CALDO DE FERMENTACION EN EL QUE HAY PRESENTE UNA FUENTE DE ADENINA EN EL MEDIO, EN UNA CANTIDAD EN EXCESO CON RESPECTO A LA CANTIDAD DE ADENINA QUE SERIA NECESARIA EN UN CULTIVO AEROBIO USANDO AIRE ORDINARIO; SEGUNDA, SE CULTIVA EN DICHO CALDO DE FERMENTACION UN MICROORGANISMO QUE REQUIERE ADENINA Y QUE PRODUCE INOSINA Y GUANISINA; TERCERA, AL MISMO TIEMPO QUE SE CULTIVA DICHO MICROORGANISMO SE HACE BURBUJEAR EN EL CALDO DE FERMENTACIONUN GAS RICO EN OXIGENO; Y POR ULTIMO, SE RETIRA DE DICHO CALDO DE CULTIVO LA INOSINA Y GUANOSINA PRODUCIDA.
