METHOD FOR THE PROTEIN ENRICHMENT OF MICROALGAL BIOMASS

The invention relates to a method for the protein enrichment of a heterotrophically cultured microalga, the microalga being of the genus Chlorella, even more particularly Chlorella protothecoides, characterized in that it comprises:a first step directed toward limiting the ammonium supply so as to o...

More Information
Summary:The invention relates to a method for the protein enrichment of a heterotrophically cultured microalga, the microalga being of the genus Chlorella, even more particularly Chlorella protothecoides, characterized in that it comprises:a first step directed toward limiting the ammonium supply so as to obtain a microalgal biomass with a protein content of less than 50% expressed as N.6.25, preferably less than 30%, more preferentially between 20 and 25%;a second step in which the ammonium supply in the fermentation medium is increased so as to obtain a protein content of greater than 50%, preferably greater than 60%, more preferentially greater than 65%.
