Défis actuels liés à la production en une étape de l'acide l-ascorbique.

L'acide ascorbique (L-AA, vitamine C) est une vitamine essentielle largement utilisée en tant que nutriment ou médicament dans les industries des produits pharmaceutiques, des cosmétiques, des produits pour l'alimentation, des boissons et des aliments pour animaux, et représente la plus grande part du marché. marché mondial des vitamines. La L-AA est principalement produite par un procédé de fermentation classique en deux étapes, qui souffre de l'utilisation d'un système de culture en plusieurs étapes et de deux cycles de stérilisation, ce qui augmente considérablement le coût du produit final. Une fermentation en une étape a été tentée, mais une méthode rivalisant avec l'efficacité du procédé en deux étapes n'a pas encore été mise au point à l'échelle industrielle. Dans cette revue, sur la base des procédés de fermentation classiques classiques en deux étapes et d'autres voies potentielles de production de L-AA, les défis et les pièges d'un processus de fermentation en une étape sont résumés. Les perspectives de production de L-AA par fermentation en une étape et la façon dont cela pourrait être réalisé sont également discutées.
