RESUMO

Kanamycin production by Streptomyces kanamyceticus ATCC 12853 requires magnesium sulfate and potassium phosphate at concentrations of 0.4 and 1.0 g per liter, respectively. The optimal concentrations of Fe and Zn for production of kanamycin are 0.25 and 0.575 μg/ml, respectively, whereas Mo at 0.04 μg/ml allows maximal cellular growth and antibiotic synthesis. Mn and Ca are without any effect. Cu, Co, Ni, and V have inhibitory effect on growth of the organism as well as kanamycin formation.
