  • Patent number: 10550413
    Abstract: The present invention generally relates to a genetically modified fungal cell capable of producing a very long, chain fatty acid (VLCFA) and/or a VLCFA derivative. The genetically modified fungal cell comprises at least one exogenous gene encoding a fatty acyl-CoA reductase, and at least one gene encoding an elongase, and/or at least one gene encoding a fatty acid synthase.

  • Patent number: 10533198
    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.
