  • Publication number: 20250092436
    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.

  • Patent number: 11162119
    Abstract: The present invention relates to the provision of genetically modified fungal cells, such as yeast cells with an improved ability for producing different fatty acids and specifically fatty acid ethyl esters (FAEE), the main components of biodiesel. An increased in fatty acid production, and hence in FAEE, is obtained in the first place by expressing different heterologous polypeptides in combination with the down-regulation, attenuation, deletion or over-expression of specially selected genes, wherein said genes encode enzymes involved in the fatty acids synthesizing pathway, fatty acid consuming pathways, carbohydrate biosynthesis pathways or enzyme acting as wax ester transporters or a combination thereof. The methods and products of the invention would allow large-scale production of FAEE with carbohydrates as the only externally-supplied substrate.
