Title (EN) IMMOBILIZED ENZYME/CELL SYSTEM FOR THE PRODUCTION OF ALPHA-KETO ACIDS
(FR) ENZYME/SYSTEME DE CELLULE IMMOBILISE POUR LA PRODUCTION D"ACIDES (ALPHA) CETONIQUES
Abstract: front page image
(EN)(Alpha)-keto acids are prepared from the corresponding amino acids by using a biocatalyst of a microbial origin, which has been immobilized in a polymeric matrix. The immobilized biocatalyst is effective and specific for the synthesis of (Alpha)-keto acids from D-amino acids. The product can easily be separated from the particulate catalyst. In the synthesis reaction, hydrogen peroxide is formed, which can be decomposed by a catalyst which also can be immobilized in the polymeric matrix. The invention can be used in continuous or discontinuous processes for the preparation of (Alpha)-keto acids from the corresponding D, L- or D amino acids.
(FR)Des acides (Alpha) cetoniques sont prepares a partir des amines acides correspondants en utilisant un biocatalyseur d"origine microbienne qui a ete immobilise dans une matrice polymere. Le biocatalyseur immobilise est effectif et specifique pour la synthese des acides (Alpha) cetoniques a partir des acides D-amines. Le produit peut etre facilement separe du catalyseur particulaire. Dans la reaction de synthese, de l"eau oxygenee se forme qui peut etre decomposee par un catalyseur qui peut egalement etre immobilise dans la matrice polymere. L"invention peut etre utilisee dans des procedes continus ou discontinus pour la preparation des acides (Alpha) cetoniques a partir des D, L ou D-amines acides correspondants.
