[Stability of biocatalysts on the basis of carrageenan-immobilized Escherichia coli during continuous synthesis of L-malic acid].
Continuous enzymatic synthesis of L-malic acid from potassium fumarate in packed-bed flow reactors was investigated. Carrageenan-immobilized Escherichia coli cells were used as a biocatalyst. The operational stability of the biocatalyst fumarase activity was studied, and conditions for preserving high activity of the biocatalyst were determined.
