Abstract
The invention discloses a method for producing lysine by utilizing adsorption and immobilized fermentation of a recombinant, wherein the recombinantis constructed by simultaneously overexpressing an adenosine triphosphate ATPase while knocking out an extracellular nuclease ExeR in a. The recombinantcan effectively improve eDNA secretion of theand reduce eDNA degradation of the, so that thecan be more easily adsorbed on a surface of a solid carrier for immobilized fermentation, such that a yield of continuous immobilized fermentation of theis increased by 49.67% than that of free fermentation of an original bacterium, and a fermentation cycle is shortened by 29.17%.
