Kanamycin was found by Umezawa et al. in the culture broth of Streptomyces kanamyceticus in 1957. It is produced with other components, kanamycins B (bekanamycin) and C, which are also separated during the purification. The compound shows much lower toxicity than the earlier aminoglycosides, streptomycin and neomycin, and strong activity against a wide range of gram-positive and gram-negative bacteria, including Mycobacterium. Kanamycin has been used clinically for treatment of such serious infections as dysentery, salmonellosis, and tuberculosis.

Kanamycin sulfate is a broad spectrum aminoglycoside-antibiotic derived from Streptomyces kanamyceticus. It is used as an additive in culture media for the isolation of group D streptococci on Kanamycin Esculin Azide Agar and for selection of transformed plant cells containing the neomycin phosphotransferase on a kanamycin-medium. Kanamycin sulfate can also be used as a selection agent for cells transformed with kanamycin B resistance gene. It is recommended for use in cell culture applications at 2 mL/L.
