With a total of 3 patents to his name, Guo's work has the potential to impact various industrial fermentation processes.

Latest Patents

One of Guo's latest patents is a method for decreasing pyruvate catabolism and increasing the accumulation of pyruvate in microbes. This invention provides a method to overexpress wild type dihydrolipoamide acetyltransferase or its mutants, which have mutations at conservative active sites. By doing so, the overall activity of the pyruvate dehydrogenase complex is decreased, leading to an increase in extracellular pyruvate accumulation without harming the pyruvate-producing microbes. Another notable patent involves a genetically engineered strain that enhances extracellular secretion of pyruvic acid. This strain, obtained from the China Center for Type Culture Collection, has improved temperature tolerance and extracellular concentration of pyruvate through the overexpression of an optimized CutA stress protein.
