Title

(EN) METHODS FOR PRODUCING POLYUNSATURATED FATTY ACIDS FROM AQUACULTURE RESIDUES

(FR) PROCÉDÉS DE PRODUCTION D'ACIDES GRAS POLYINSATURÉS À PARTIR DE RÉSIDUS D'AQUACULTURE

Abstract

(EN) The present application relates to valorization of aquaculture residues. More specifically, the present application relates to methods for producing polyunsaturated fatty acids (PUFAs) from aquaculture residues. For example, a method can comprise: fermenting at least one aquaculture residue in the presence of at least one microorganism to produce a biomass comprising PUFAs, optionally isolating the PUFAs, wherein the at least one microorganism is a marine protist microorganism from species selected from Sphaeroforma, Crypthecodinium, Aurantiochytrium, Thraustochytrium and Oblongichytrium. The present application includes biomass produced therefrom, use thereof and kit for producing PUFAs from aquaculture residues.

(FR) La présente demande concerne la valorisation de résidus d'aquaculture. Plus précisément, la présente demande concerne des procédés de production d'acides gras polyinsaturés (AGPI) à partir de résidus d'aquaculture. Par exemple, un procédé peut comporter : la fermentation d'au moins un résidu d'aquaculture en présence d'au moins un micro-organisme pour produire une biomasse comprenant des AGPI, et éventuellement l'isolement des AGPI, l'au moins un micro-organisme étant un micro-organisme protiste marin appartenant à une espèce choisie parmi Sphaeroforma, Crypthecodinium, Aurantiochytrium, Thraustochytrium et Oblongichytrium. La présente invention concerne la biomasse produite à partir de celle-ci, l'utilisation associée et un kit pour produire des AGPI à partir de résidus d'aquaculture.
