Resumo
Understanding the diversity and metal removal ability of microorganisms associated to contaminated aquatic environments is essential to develop metal remediation technologies in engineered environments. This study investigates through 16S rRNA deep sequencing the composition of a biostimulated microbial consortium obtained
from the polluted Tietê River in São Paulo, Brazil. The bacterial diversity of the biostimulated consortium obtained
from the contaminated water and sediment was compared to the original sample. The results of the comparative
sequencing analyses showed that the biostimulated consortium and the natural environment had γProteobacteria, Firmicutes, and uncultured bacteria as the major classes of microorganisms. The consortium optimum zinc removal capacity, evaluated in batch experiments, was achieved at pH = 5 with equilibrium contact
time of 120 min, and a higher Zn-biomass affinity (KF = 1.81) than most pure cultures previously investigated.
Analysis of the functional groups found in the consortium demonstrated that amine, carboxyl, hydroxyl, and
phosphate groups present in the consortium cells were responsible for zinc uptake.
