Latest Patents

Fuxin Sun's latest patents include innovative methods for citric acid production. One of his patents, titled "Aspergillus niger seed continuous culture and method for producing citric acid therefrom," discloses a continuous culture method that addresses the challenges of slow growth in multi-cellular filamentous bacteria. This method involves inoculating spores into a seed culture medium, performing continuous dispersion treatment, and ultimately transferring the seed liquid into a fermentation medium for culture. This breakthrough effectively resolves issues related to mycelium pellet loss during continuous culture.

Another significant patent is the "Method for reconstructing Aspergillus niger to increase citrate production." This invention involves inserting a gene for a low affinity glucose transporter, LGT1, into the genome of Aspergillus niger. The modified strain exhibits improved tolerance to higher fermentation temperatures and lower pH levels, resulting in higher production, yield, and purity of citric acid compared to the parental strain, while also reducing fermentation time.
