Patents by Inventor Florian David

Florian David has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20260035727
    Abstract: The present invention related to the provision of genetically modified fungal cells, such as yeast cells with an improved ability for producing and secreting different recombinant proteins. The improved ability is obtained by disruption in intracellular transport between the Golgi and the endosome. In particular embodiments, the disruption is achieved by downregulation or deletion of the gene encoding a Tda3p homolog. The fungal cell and method of the invention would allow for large-scale production of recombinant proteins in fungal cells.

  • Publication number: 20250346933
    Abstract: A yeast cell for the production of fatty acids and/or fatty acid-derived products is genetically modified for overexpression of one or more endogenous yeast genes selected from the group consisting of ADP-ribosylation factor-binding protein, phosphatidylinositol 4,5-bisphosphate 5-phosphatase INP54, NADP-dependent isocitrate dehydrogenase IDP3, mitochondrial phosphatidylglycerophosphatase GEP4, triglyceride lipase TGL1, long chain fatty acyl-CoA synthetase FAA3, lipid phosphate phosphatase LPP1, and variants of such endogenous yeast genes. The yeast cell produces higher amount of fatty acids and/or fatty acid-derived products compared to a yeast cell not overexpressing the one or more endogenous yeast genes.

  • Patent number: 10544435
    Abstract: The present invention relates to the provision of genetically modified microbial cells, such as yeast cells with an improved ability for producing L-ornithine and its derivatives. Overproduction of L-ornithine is obtained in the first place by the down-regulation or attenuation of specially selected genes, wherein said genes encode enzymes involved in the L-ornithine consumption and/or degradation pathways. Further L-ornithine production ability is improved by down-regulation, attenuation, deletion or overexpression of specially selected genes, wherein said genes encode enzymes and/or proteins involved in the L-ornithine ‘acetylated derivatives cycle’, L-glutamate synthesis pathways, subcellular trafficking, TCA cycle, pyruvate carboxylation pathway, respiratory electron-transport chain, and the carbon substrates' assimilation machinery. The invention additionally provides a method to produce L-ornithine with said modified eukaryotic cells.
