摘要：

This study aims to evaluate the biodegradation of 2,4-dichlorophenoxyacetic acid (2,4-D) by bacterial strains isolated from country vegetation in Maranhao, Brazil. The microorganisms selected for biodegradation of 2,4-D in solid culture media were effective. The bacterial strains from cultivation soil of bean (F5 and F7) and cassava (M5 and M6) were the best adapted to the culture media containing the herbicide. Microorganism growth was greater in the presence of 2,4-D when extra source of carbon and nitrogen was added. All microorganisms were effective in inactivating the herbicide; the stain F7 showed the greatest percentage of biodegradation of 2,4-D (92 %).
