Title (EN) CELLS OR PLANTS HAVING A PRODUCING ABILITY OF POLYLACTATE OR ITS COPOLYMERS AND METHOD FOR PREPARING POLYLACTATE OR ITS COPOLYMERS USING THE SAME
(FR) CELLULES OU PLANTES POSSEDANT LA CAPACITE DE PRODUCTION DU POLYLACTATE OU SES COPOLYMERES ET PROCEDE DE PREPARATION DU POLYLACTATE OU SES COPOLYMERES LES UTILISANT
Abstract: front page image
(EN)The present invention relates to cells or plants having the ability of producing polylactate or its copolymers and a method for preparing polylactate or its copolymers using the same, more specifically, relates to cells or plants having the ability of producing polylactate or hydroxyalkanoate-lactate copolymers, which simultaneously have a gene encoding an enzyme converting lactate into lactyl-CoA and a gene encoding polyhydroxyalkanoate(PHA) synthase capable of using lactyl- CoA as a substrate, and a method for preparing polylactate or hydroxyalkanoate- lactate copolymers, the method comprises: culturing the cells in a medium containing lactate or lactate and various hydroxyalkanoates or culturing the plants. According to the present invention, it is possible to effectively prepare hydroxyalkanoate-lactate copolymer which contains various kinds of hydroxyalkanoates as well as polylactate by using the cells or the plants.
(FR)L'invention concerne des cellules ou des plantes possédant la capacité de produire du polylactate ou ses copolymères ainsi qu'un procédé de préparation du polylactate ou ses copolymères les utilisant. Plus précisément, l'invention concerne des cellules ou des plantes possédant la capacité de produire du polylactate ou des copolymères hydroxyalcanoate-lactate, qui possèdent simultanément un gène codant pour un enzyme transformant le lactate en lactyl-CoA et un gène codant pour polyhydroxyalcanoate (PHA) synthase pouvant utiliser le lactyl-CoA comme substrat, et un procédé de préparation de copolymères polylactate ou hydroxyalcanoate-lactate, le procédé consistant à cultiver les cellules dans un milieu contenant du lactate ou du lactate et divers hydroxyalcanoates ou à cultiver des plantes. Selon l'invention, on peut préparer avec efficacité un copolymère hydroxyalcanoate-lactate contenant différents types d'hydroxyalcanoates ainsi que du polylactate en utilisant les cellules ou les plantes.
