These novel groups of archaea named ARMAN-1, ARMAN-2 (Candidatus Micrarchaeum acidiphilum ARMAN-2 ), and ARMAN-3 were missed by previous PCR-based surveys of the mine community because the ARMANs have several mismatches with commonly used PCR primers for 16S rRNA genes.
Estes novos grupos de arqueas atopados, que foron denominados ARMAN-1, ARMAN-2 (Candidatus Micrarchaeum acidiphilum ARMAN-2 ), e ARMAN-3, pasaran indetectados en estudos previos da comunidade de organismos desa mina baseados na PCR porque os ARMANs teñen varias faltas de correspondencia cos cebadores ou primers normalmente usados nas PCR para os xenes do ARNr de 16S.
