摘要： A process for separating basic amino acids from a liquid containing the same using cation exchange resin towers in series, which comprises effecting repetitive adsorption and elution steps in sequence, wherein the washing water employed in said adsorption and elution steps is obtained by recycling the latter portion of a liquid discharged from a first tower of the adsorption step into an adsorption step in a subsequent cycle, or by recycling a liquid discharged from a first tower at the elution step into an elution step in a subsequent cycle.

摘要： A hydrolyzate of molasses, containing both glucose and fructose, is mixed with calcium hydroxide, and a fructose addition precipitate is recovered. The residual liquor is neutralized, calcium ions are removed, and then the liquor is used as a carbon source for glutamic acid or lysine fermentation.The present method may supply very inexpensive fructose to the market.

摘要： A method for separating a basic amino acid from a liquor containing the same, which entails (a) contacting the basic amino containing liquor with a strongly acidic cation exchange resin at a pH at which the basic amino acid exists in the form of a divalent cation, thereby adsorbing at least a part of the basic amino acid in the form of the divalent cation; (b) contacting said ion exchange resin with a liquor containing said basic amino acid and a neutral amino acid or an acidic amino acid at a pH at which the basic amino acid exists in the form of a monovalent cation; (c) passing an eluant through said ion exchange resin, thereby eluting the basic amino acid from the ion exchange resin; and (d) separating and recovering the basic amino acid from the eluate.
摘要翻译：一种从含有该碱性氨基酸的液体中分离碱性氨基酸的方法，其包括（a）在碱性氨基酸以二价阳离子形式存在的pH下使碱性氨基含量的液体与强酸性阳离子交换树脂接触从而吸附二价阳离子形式的至少一部分碱性氨基酸; （b）在碱性氨基酸以单价阳离子的形式存在的pH下使所述离子交换树脂与含有碱性氨基酸和中性氨基酸或酸性氨基酸的液体接触; （c）使洗脱液通过所述离子交换树脂，从而离子交换树脂洗脱碱性氨基酸; 和（d）从洗脱液中分离和回收碱性氨基酸。

摘要： The present invention relates to L-phenylalanine 1/2 sulfate and its use in the purification of L-phenylalanine from fermentation broths. When the salt is crystallized from a fermentation broth of L-phenylalanine or a solution produced during an intermediate process of recovering L-phenylalanine from the fermentation broth, impurities derived from the fermentation broth are easily removed.
