Claim:
1. A process for producing amino acids from volatile fatty acid (VFA) molecules, referred to as precursors, produced by anaerobic fermentation from fermentable biomass, comprising: a) extracting the volatile fatty acid (VFA) molecules, without stopping the fermentation, via an extraction means chosen from means that are, at least, insoluble in the fermentation medium; b) collecting, outside the fermentation reactor, the volatile fatty acid (VFA) molecules once they have been extracted; c) synthesizing, by halogenation, using a type of volatile fatty acid (VFA) chosen from the volatile fatty acids collected in step b) and defined according to the desired type of amino acid, a given α-halo acid; and d) synthesizing from this α-halo acid a defined amino acid, wherein, during step c), an anhydride corresponding to the volatile fatty acid (VFA) to be halogenated is used.
