“…It accounted for 8 % when the NaCl concentration was 28 g L -1 . Early study reported that archaeal cells, detected by the ARC915 probe, accounted for 77, 84 and 75 % with the COD/SO 4 2-ratios of 3.0, 2.0 and 1.6, respectively (Hirasawa et al 2008). In this work, the COD/SO 4 2-ratio was fixed at 2.25, and the abundances of archaea in each salinity stage were lower than the report.…”

“…O inóculo do reator anaeróbio é proveniente de um sistema com longo tempo de operação e apresenta grânulos com grande diversidade microbiana (Hirasawa et al, 2008), resultando em maior capacidade de adaptação às condições impostas (pH baixo e presença de metais pesados). O inóculo obtido na mina é proveniente do sedimento que margeia as lagoas de depósito de drenagem ácida, um ambiente bastante desfavorável à diversidade microbiana, em função do baixo pH (próximo a 3) e concentração de metais pesados.…”

“…Nessa fase do reator R2, o pH estava mais favorável ao estabelecimento de outras comunidades microbianas. O inóculo utilizado nesses estudos é proveniente de um reator anaeróbio com longo tempo de operação e apresenta grânulos com grande diversidade microbiana (Hirasawa et al, 2008), resultando em maior capacidade de adaptação às inúmeras condições impostas.…”
