Resumo: This study aimed to evaluate the soil microbiota activity associated to S. aterrimum rhizosphere, during the phytoremediation process of a soil contaminated with trifloxysulfuron-sodium. S. aterrimum was cultivated in vases (6,0 L) filled with soil, after trifloxysulfuron-sodium, at 7.5 g ha-1, was applied or not. Every 15 days after sowing (DAS), rhizospheric soil was collected for soil microbial respiration (amount of evolved CO2) and microbial biomass carbon (MBC) analysis. To determine herbicide residues in the soil samples, after phytoremediation, Sorghum bicolor L. was cultivated as an indicator species, in addition to high performance liquid chromatography (HPLC) analysis. The microbiota associated to S. aterrimum rhizosphere showed to be sensitive to trifloxysulfuron-sodium and may be used as a microbiological indicator of disturbances caused by this herbicide in the environment. Regarding time for remediation, 45 days of development is enough for S. aterrimum to reduce residual trifloxysulfuron-sodium to a level not able to cause toxicity to the indicator plant. KEY-WORDS: Microbiological indicator; phytoremediation; microbial biomass.

Objetivou-se, com este trabalho, avaliar a atividade da microbiota associada à rizosfera de Stizolobium aterrimum, durante processo de fitorremediação de solo contaminado com o herbicida trifloxysulfuron-sodium. Em vasos com capacidade para seis litros, após aplicação ou não de 7,5 g ha-1 do herbicida trifloxysulfuron-sodium, cultivou-se a espécie vegetal S. aterrimum. Após a semeadura, procedeu-se à coleta de solo rizosférico, quinzenalmente, para determinação da respiração da microbiota do solo (quantidade de CO2 evoluído) e carbono da biomassa microbiana (CBM). Para determinação do resíduo do herbicida nas amostras de solo, após a remediação, cultivou-se sorgo (Sorghum bicolor L.), como espécie bioindicadora, além de ser efetuada análise por cromatografia líquida de alta eficiência (CLAE). Observou-se que a microbiota associada à rizosfera de S. aterrimum é sensível ao trifloxysulfuron-sodium, constituindo-se indicador microbiológico de distúrbios causados por este herbicida no ambiente. Quanto ao tempo para remediação, constatou-se que 45 dias de desenvolvimento é tempo suficiente para que S. aterrimum promova a diminuição do resíduo de trifloxysulfuron-sodium a um nível incapaz de causar toxicidade à planta indicadora.
