摘要: When immobilizing cells and/or enzymes by contact with tannin, epihalohydrin/polyamine copolymer and glutaraldehyde, immobilizing is carried out in the presence of a primary amine. The primary amine is preferably sulfuric acid mono-(2-aminoethyl)-ester, 2-aminoethanol, glycine or tris-(hydroxymethyl)-amino methane. The resulting immobilized cells and/or enzymes retain a higher proportion of their original activity.

摘要: A process for concentrating nikkomicins (X) and (Z) from a dilute impure aqueous solution thereof, comprising contacting the solution with a weakly basic ion exchanger and eluting the adsorbed material with an acid thereby to obtain a concentrated mixture of nikkomicin (X) and nikkomicin (Z). The dilute solution being treated can directly be a filtered microbial cultivation liquor or such a liquor can be prepurified by contact with an acid ion exchanger followed by elution with a base. The recovered material is of relatively high purity.
