[Objective] To screen out a microbial flocculant with good decolorization effect on methyl orange wastewater, and study the effect of different cultural conditions on decolorization effect of methyl orange. [Method] Absorbance of methyl orange solution before and after decolorization was determined by spectrophotometer, and the decolorization rate was calculated to compare the effects of different cultural conditions on removal rate of methyl orange. [Result]An optimal actinomycete stain（F-1-2） was screened out, and the best cultural condition was as follows: with sucrose as carbon source and NaNO3 as nitrogen source, cultured in constant temperature oscillator at 150 r/min, 30℃ for 72 h. Under the optimal condition, the removal rate against methyl orange could reach 68.4%. [Conclusion]Different cultural conditions had great impact on decolorization effect of strain.
