(DE) VERFAHREN ZUR HERSTELLUNG VON L-AMINOSÄUREN UNTER VERWENDUNG EINES BAKTERIUMS DER FAMILIE DER ENTEROBACTERIACEAE MIT ÜBEREXPRESSION EINES FÜR EINEN EISENEXPOTER CODIERENDEN GENS
(EN) A METHOD FOR PRODUCING L-AMINO ACIDS USING A BACTERIUM OF THE FAMILY ENTEROBACTERIACEAE OVEREXPRESSING A GENE ENCODING AN IRON EXPORTER
(FR) PROCÉDÉ DE PRODUCTION D'ACIDES L-AMINÉS FAISANT APPEL À UNE BACTÉRIE DE LA FAMILLE DES ENTEROBACTERIACEAE SUREXPRIMANT UN GÈNE CODANT POUR UN EXPORTEUR DE FER
Abstract
(EN)
The present invention provides a method for producing L-amino acids by fermentation using a bacterium belonging to the family Enterobacteriaceae which has been modified to overexpress a gene encoding an iron exporter, such as a fetB gene, fetA gene, fieF gene, or a combination of these genes.

(FR)
