%X this work assessed the bioremediation of herbicide velpar k£¿, in vitro in aqueous solution, used against weeds in sugar cane in s£¿o paulo state. the herbicide contained hexazinone and diuron. it was used the microbial inoculant denominated effective microorganisms (em-4), pool of microorganisms from soil that contained lactic and photosynthetic bacteria, fungi, yeasts and actinomycetes for bioremediation. results for the depth of cultivation on agar-agar inoculated with em-4 showed the microorganisms growth in the concentrations between 0.2% and 1.0% of the velpar k£¿in the gel. the analysis of high performance liquid chromatography (hplc) showed that the em-4 was effective for the bioremediation of the herbicide, which reached the values of 80% for diuron and 70% for hexazinone after 21 days in solution of 2:1 of velpar k£¿/em-4 ratio. these results could be useful for planning the bioremediation of contaminated areas with velpar k£¿.
