| Abstract: | Effect of N sources and heavy metal ions on cell growth, pH and rifamycin oxidase (RO) productivity by Chryseobacterium
sp. was observed. Supplementation of malt extract showed pH close to neutral for 24 h followed by slight increase, whereas RO
productivity significantly enhanced (36 IU ml ⁻¹) as compared to control (29 IU ml⁻¹) within 12 h. RO production was
considerably stimulated in presence of Ca⁺⁺, K⁺ and Na⁺. Chryseobacterium sp. showed increase in enzyme activity by
38.77 % in presence of Ca2⁺ and K⁺ and 48.77 % in presence of Na⁺. |
