Verfahren zur Herstellung von L-Asparaginsäure |
摘要 |
This invention relates to a method for producing L-aspartic acid, comprising the steps of: immobilizing microbial cells containing aspartase to produce an immobilized aspartase; feeding an ammonium fumarate solution into a reactor filled with the immobilized aspartase; and recovering the produced L-aspartic acid from the reaction mixture, wherein the immobilized aspartase has an activity of 250 U or more, and wherein the ammonium fumarate solution is fed into the reactor at the feed rate LHSV of 2 to 35. |
