Latest Patents
Chunguang Zhao has developed several innovative patents, including the "Escherichia Coli-Based Recombinant Strain, Construction Method Therefor And Use Thereof." This patent provides a nucleotide sequence formed by mutation of a base at the 1049th site of a wild-type deoB gene coding sequence. It also includes a promoter nucleotide sequence that has been mutated at the -67th site upstream of a specific nucleotide sequence. The resulting recombinant strain is capable of producing L-threonine at higher concentrations, thereby reducing production costs and demonstrating good strain stability. Another significant patent is the "Method For Producing L-Lysine By Modifying Aconitase Gene And/or Regulatory Elements Thereof." This method involves modifying the aconitase gene on a bacterial chromosome to reduce enzymatic activity, allowing for the generation of L-lysine through fermentation.
