FIELD: biotechnology, amino acids, peptides.
SUBSTANCE: invention relates to a method for preparing a mixture consisting of amino acids and lower peptides from yeast autolyzates. Method involves autolysis of yeast, separation of cellular debris by centrifugation and purification of autolyzate in ionites resins wherein gel sulfocation-exchange resin in hydrogen form comprising 12-16% of divinylbenzene as a cross-linking agent is used as ionite. Proposed method provides preparing highly purified mixture of amino acids with the low content of peptides.
EFFECT: improved preparing method.
