Title: Innovations of Inventor Nan Zheng
Introduction
Nan Zheng is a prominent inventor based in Beijing, China. He has made significant contributions to the field of microbial DNA extraction and separation technologies. With a total of 3 patents to his name, Zheng's work has the potential to impact various applications in biotechnology and agriculture.
Latest Patents
One of Zheng's latest patents is a method for extracting total microbial DNA from milk. This innovative method allows the extracted DNA to be directly used for PCR amplification. The process involves treating milk with TE solution, fully disrupting microbial cells through bead milling, and immobilizing proteins in the middle layer between the aqueous and organic phases using high-vacuum silicone grease. This technique ensures that impurities do not enter the aqueous phase, resulting in extracted DNA that boasts a high degree of intactness, concentration, and purity.
Another notable patent is a method for enriching and separating anaerobic fiber-degrading bacteria using cellulosic magnetic nanoparticles. In this method, cellulosic magnetic nanoparticles are prepared by coating cellulose on the surface of a magnetic nanomaterial. Bacteria attach to these nanoparticles, and as anaerobic fiber-degrading bacteria degrade the cellulose, they detach from the nanoparticles. This innovative magnetic nano-separation technology provides an efficient means of isolating anaerobic fiber-degrading bacteria.
