Bioprocess for coproduction of ethanol and mycoproteins
First Claim
Patent Images
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.
