Title: Yanfeng Liu: Innovator in Human Milk Lipid Substitute and N-acetylneuraminic Acid Production
Introduction
Yanfeng Liu is a prominent inventor based in Wuxi, China. He has made significant contributions to the fields of genetic engineering and food science, particularly in the development of substitutes for human milk lipids and the production of N-acetylneuraminic acid. With a total of 4 patents, Liu's work is paving the way for advancements in nutritional science.
Latest Patents
Liu's latest patents include a strain for producing a human milk lipid substitute. This invention integrates a heterologous lysophosphatidic acid acyltransferase while knocking out its natural counterpart. This process increases the content of palmitic acid (C16:0) at the Sn-2 position of triacylglycerol, allowing for the synthesis of a human milk lipid substitute. The invention achieves a total fatty acid content of 15% or more, with the relative content of C16:0 at Sn-2 position reaching about 60%.
Another notable patent involves the production of N-acetylneuraminic acid. This innovation optimizes the expression levels of key enzymes in the synthesis pathways through the use of promoters of varying strength. By reducing the protein synthesis pressure on cells, Liu's method integrates three N-acetylneuraminic acids into a single engineering strain, achieving a production level of 10.4 g/L at the shake flask level.
