In order to separate and refine r-L-glutamyl...3-aminoproline accumulated in the culture, amino acids,
Methods for separating peptides are applied as appropriate. In other words, γ-L-glutami-3-aminoproline is accumulated in the bacterial strain and culture solution, but γ-L-g, glutami, and 3-aminoproline in the bacterial body are It can be purified by extraction with a solvent for 1 year, followed by an appropriate combination of ion exchange resin, chromatogelane using cellulose, and gel filtration. As the aqueous solvent, water or water-ethanol is usually used, but instead of water-ethanol, a mixed solvent of water and a hydrophilic solvent such as methanol or acetone can also be used. □Also, if desired, a hydrophilic solvent may be used alone.

抽出は常温で行うが加温してもよい。Extraction is performed at room temperature, but may be heated.
