Azo dyes accounts for the majority of all textile dyestuffs produced and have been most commonly used synthetic dyes in the textile, paper and leather industries. Methyl Orange is one such azo dye, which is widely used in textile industries and also as an indicator in chemical laboratories. In the present study effect of NaCl salt concentration, effect of presence or absence of nitrogen source and phytotoxicityof Methyl orange and its degradation products is studied. Presence of 5g/l of NaCl did had any negative impact on decolorization efficiency. There was slight delay in time taken for decolorization at and above 20g/l of NaCl in the media. Optimum amount of peptone for the efficient decolorization was found to be 5g/l. Presence of less than or more than 5g/l of peptone has delayed the decolorization time  and reduced the decolorization efficiency.
