Abstract

En la presente se dan a conocer metodos para la produccion de azucar fermentable obtenido de un tejido vegetal. Los metodos incluyen la obtencion de un material vegetal que comprende uno o m s carbohidratos bloqueados y poner en contacto al material vegetal con una enzima con capacidad de convertir el carbohidrato bloqueado a un azucar fermentable. Los metodos son utiles para producir azucar o precursores de azucar para varios fines industriales, entre los que se incluye la produccion de etanol. La solicitud abarca asimismo plantas y partes de plantas que producen una enzima bloqueadora para producir un carbohidrato bloqueado, con la consecuencia de la acumulacion del carbohidrato bloqueado en la planta. La solicitud abarca adem s la obtencion de una enzima clave para convertir carbohidratos bloqueados a azucares fermentables. Las enzimas clave pueden ser producidas por plantas o partes de plantas transgenicas, microbios transgenicos, levadura transgenica, microbios o levadura. Reivindicacion 53: Un metodo para la produccion de azucar fermentable que comprende: a) obtener un material de planta transgenica, donde dicho material de planta transgenica es seleccionado del grupo que consiste en remolacha azucarera, sorgo, ma¡z, y cana de azucar, y donde dicho material de planta transgenica comprende: i) una o m s enzimas bloqueadoras donde dichas una o m s enzimas bloqueadoras son seleccionadas del grupo que consiste en dextransacarasa, levan sacarosa, alternansacarasa, sacarosa isomerasa y amilosacarasa, ii) uno o m s carbohidratos bloqueados donde dichos uno o m s carbohidratos bloqueados son seleccionados del grupo constituido por isomaltulosa, trehalulosa, leucrosa, almidon, dextranos, fructanos, maltosa, turanosa e isomaltosa, iii) una o m s enzimas clave donde dichas una o m s enzimas clave son seleccionadas del grupo que consiste en dextranasa, alfa-amilasa, glucoamilasa, alfa-1,5-glucosidasa, alfa-1,1-glucosidasa y alfa-1,6- glucosidasa; y donde dichas una o m s enzimas clave son dirigidas a un sitio alejado de dichos uno o m s carbohidratos bloqueados; y b) procesar dicho material de planta transgenica en condiciones suficientes para que dichas una o m s enzimas clave conviertan dichos uno o m s carbohidratos bloqueados a azucar fermentable.
