Abstract:
(EN) A method for producing bacterial cellulose membranes comprising: inoculating a pre-inoculum of a microorganism from Komagataeibacter xylinus strain DSMZ 2004 in a culture medium containing reducing sugars from mango (Mangifera indica), as well as yeast extract; incubating at 30 °C for 15 days; purifying the bacterial cellulose membranes obtained by washing with distilled water at 3200 rpm then immersing them in a 0.1 M NaOH solution and maintaining them at 90 °C for 30 min; then washing the membranes with distilled water until the pH of the wash water is 7. A bacterial cellulose membrane obtained using the method of the present invention, which may be useful in biomedical applications; and a product useful in biomedical applications, which in turn comprises the bacterial cellulose membrane according to the present invention.
(FR) L’invention concerne un procédé pour la production de membranes de cellulose bactérienne, qui consiste : à inoculer un pré-inoculum d’un micro-organisme de Komagataeibacter xylinus souche DSMZ 2004, dans un milieu de culture qui contient des sucres réducteurs de mangue Mangifera indica, et un extrait de levure ; à incuber à 30 ºC, pendant 15 jours ; à purifier les membranes de cellulose bactérienne obtenues, en les lavant avec de l’eau distillée à 3200 rpm, pour ensuite les immerger dans une solution de NaOH 0.1 M, et en les maintenant à 90 ºC pendant 30 min ; et à laver les membranes avec de l’eau distillée jusqu’à ce que le pH de l’eau de lavage soit égal à 7. L'invention concerne une membrane de cellulose bactérienne, obtenue selon le procédé de la présente invention, qui peut être utile dans des applications biomédicales ; et un produit utile dans des applications biomédicales, lequel comprend la membrane de cellulose bactérienne conforme à la présente invention.
(ES) Un método para la producción de membranas de celulosa bacteriana, el cual comprende: inocular un pre-inóculo de un microorganismo de Komagataeibacter xylinus cepa DSMZ 2004, en un medio de cultivo que contiene azúcares reductores de mango Mangifera indica, y extracto de levadura; incubar a 30º C, durante 15 días; purificar las membranas de celulosa bacteriana obtenida, lavándolas con agua destilada a 3,200 rpm, para después sumergirlas en una solución de NaOH 0.1 M, y manteniéndolas a 90º C por 30 min; y lavar las membranas con agua destilada hasta que el pH del agua de lavado es 7. Una membrana de celulosa bacteriana, obtenida con el método de la presente invención, la cual puede ser útil en aplicaciones biomédicas; y un producto útil en aplicaciones biomédicas, que a su vez comprende, la membrana de celulosa bacteriana de conformidad con la invención en cuestión.
