Abstract

LA INVENCION SE REFIERE A UN METODO DE PREPARACION DE ACIDO LACTICO PURO O DE UNA SAL DEL MISMO POR FERMENTACION. EL PROCESO DE PREPARACION CONSISTE EN UN CICLO DE REGENERACION DEL BIORREACTOR Y DE UN CICLO DE PRODUCCION DE ACIDO LACTICO, EN EL QUE DURANTE EL CICLO DE PRODUCCION SE RECICLA UNA SOLUCION CONSTITUIDA ESENCIALMENTE POR MATERIA PRIMA BRUTA PURA A TRAVES DE UN BIORREACTOR QUE CONTIENE MICROORGANISMOS REGENERADOS, NEUTRALIZANDOSE EL ACIDO LACTICO PRODUCIDO MEDIANTE LA ADICION DE UN ALCALI; EL RECICLADO SE INTERRUMPE CUANDO EL CONSUMO DEL ALCALI DISMINUYE NOTABLEMENTE; DURANTE EL CICLO DE REGENERACION LOS MICROORGANISMOS SE REGENERAN MEDIANTE EL RECICLADO A TRAVES DEL BIORREACTOR DE UNA SOLUCION DE CARBOHIDRATOS ENRIQUECIDA CON NUTRIENTES, CON LO QUE SE RECUPERA LA CAPACIDAD DE LOS MICROORGANISMOS PARA PRODUCIR UN ACIDO, Y POR TANTO LA RECUPERACION DE LACTATO O LA CONVERSION DEL MISMO EN ACIDO LACTICO U OTRA SAL.
