Abstract: Disclosed are a phosphinothricin dehydrogenase mutant, a recombinant bacterium and a one-pot multi-enzyme synchronous directed evolution method. The phosphinothricin dehydrogenase mutant, with an amino acid sequence as shown in SEQ ID No.1, is obtained by mutating alanine at position 164 to glycine, arginine at position 205 to lysine, and threonine at position 332 to alanine in a phosphinothricin dehydrogenase derived from Pseudomonas fluorescens. The recombinant bacterium is obtained by introducing a gene encoding the phosphinothricin dehydrogenase mutant into a host cell. The host cell can also incorporate a gene encoding a glucose dehydrogenase or a gene encoding a formate dehydrogenase to undergo synchronous directed evolution to achieve double gene overexpression. The one-pot multi-enzyme synchronous directed evolution method of the present invention can screen recombinant bacteria with greatly improved activity.

Abstract: This invention provides a method for the production of high capacity cathode materials for use in rechargeable lithium batteries. Traditional methods for producing lithium mixed metal oxide cathode materials typically generate large amounts of effluent which effluent must be treated prior to discharge. The present process uses mixed metals as raw materials in a wet chemical reaction in order to make high-quality precursors which can be used to prepare high-quality cathode materials after lithiation. As a key feature, in the precursor preparation process, the bulk of the aqueous solution used for the wet chemical reaction is recycled back to the reactor, so that the total process has little or no effluent generated during production of the cathode precursor material.
