Procédé d'extraction d'un nucléotide d'un bouillon de fermentation le contenant

摘要

Nucleotides are recovered from fermentation broth by passing the broth through strongly acidic cation exchange resin, eluting absorbed nucleotide with water, passing the eluate through strongly basic anion exchange resin and eluting absorbed nucleotide with mineral acid. The broth may be filtered and/or replaced by an eluate obtained by passing the broth through strongly basic anion exchange resin and eluting absorbed nucleotide with mineral acid.
