1. An integrated method or system for producing and isolating mycoprotein produced by Fusarium venenatum and ethanol from hydrolysed starch feedstock, the method comprising the steps of:

  • a) providing an aqueous fermentable broth comprising a hydrolysed starch feedstock;

    b) a first fermentation step comprising fermenting at least a portion of the aqueous fermentable broth with Fusarium venenatum in order to obtain mycoprotein produced by Fusarium venenatum respectively and partially fermented broth;

    c) separating the mycoprotein produced by Fusarium venenatum from the partially fermented broth;

    d) a second fermentation step comprising fermenting at least a portion of the partially fermented broth, optionally with a portion of unfermented aqueous fermentable broth, with a micro-organism(s) in order to obtain ethanol and a spent fermentation residue; and

    e) isolating the ethanol from the spent fermentation residue.
