Fig. 7 Effect of nitrate-reducing-decolorized medium on growth of rice shoots. The bars are the
averages of three replicates from each treatment, and error bars indicate standard deviations from

the means. Treatments used were T1 Nitrate-reducing monoculture-decolorized medium on 7th day
of incubation, T2 Nitrate-reducing monoculture-decolorized medium on 14th day of incubation, T3
Fahreus medium (negative control) and T4 1 % Congo red solution (positive control)
