实验过程

Simulated kanamycin culture liquid is prepared by adding 80 mg of kanamycin sulfate to 160 ml of glucose-bouillon medium which is sterilized by heating at 120° C for 15 minutes. This liquid is then passed through a column (diameter: 1.5 cm), wherein 2.7 g of the molecular sieving particle containing activated charcoal obtained in Example 1 (sample (a)) is packed, at a flow rate of 0.5 ml/minute. The column is then subjected to washing with water and further to elution with 0.1N HCl-methanol (1:1) solvent. Active fractions are combined and 72.8 mg of kanamycin chloride is recovered in very high purity (decoloration degree: 99%; purity: 98%) and high yield (recovery percentage: 91%).
