Resumo
The use of sulfate-reducing bacteria (SRB)
is a cost-effective route to treat sulfate- contaminated
waters and precipitate metals. The isolation and
characterization of a SRB strain from an AMD in a
Brazilian tropical region site was carried out. With a
moderately acidic pH (5.5), the C.1 strain began its
growth and with continued growth, modified the pH
accordingly. The strain under these conditions reduced
sulfate at the same rate as an experiment performed
using an initial pH of 7.0. The dsrB gene-based
molecular approach was used for the characterization
of this strain and its phylogenetic affiliation was similar
to genus Desulfovibrio sp. The results show an SRB
isolate with unexpected sulfate reducing capacity in
moderately acidic conditions, bringing new possibilities
for the treatment of AMD, as acid water would be
neutralized to a mildly acidic condition.
