<p>The invention concerns a method for harvesting a microbial protein using a nonionic surfactant and an alcohol. More particularly, the invention relates to a method for harvesting a microbial protein from the culture of a microorganism which produces this protein, this method comprising the following steps: a) the aqueous fraction and the soluble impurities are eliminated from the culture at the end of the fermentation, the solid fraction is kept; b) a nonionic surfactant and an alcohol are added to the solid fraction, resulting in a suspension; and c) the suspension is subjected to a treatment allowing the elimination of the residual impurities and the microorganisms, the result being a composition containing the purified and concentrated microbial protein, the nonionic surfactant and the alcohol.</p> |
