[Objective]The study aimed to isolate a strain for degrading glyphosate herbicide from active sludge in sewage treating pond of Fujian Sannong Group and study its degradation characteristics. [Method] By using liquid enrichment taming and selective culture, the yeast strain S-2 that utilized glyphosate as the sole carbon and nitrogen source was isolated and its degradation characteristics was studied. [Result] The most suitable growth and degradation conditions for the strain S-2 at inoculum volume, initial pH value, culture temperature, and shaker speed were 4%, 7.0, 30 ℃ and 130-160 r/min, respectively.[Conclusion] The study provided the necessary reference for biodegradation of glyphosate and bioremediation of the polluted soils.
