Diversity of "Ca. Micrarchaeota" in Two Distinct Types of Acidic Environments and Their Associations with Thermoplasmatales.

ABSTRACT: "Candidatus Micrarchaeota" are widely distributed in acidic environments; however, their cultivability and our understanding of their interactions with potential hosts are very limited. Their habitats were so far attributed with acidic sites, soils, peats, freshwater systems, and hypersaline mats. Using cultivation and culture-independent approaches (16S rRNA gene clonal libraries, high-throughput amplicon sequencing of V3-V4 region of 16S rRNA genes), we surveyed the occurrence of these archaea in geothermal areas on Kamchatka Peninsula and Kunashir Island and assessed their taxonomic diversity in relation with another type of low-pH environment, acid mine drainage stream (Wales, UK). We detected "Ca. Micrarchaeota" in thermophilic heterotrophic enrichment cultures of Kunash
