show Abstracthide AbstractIn this study we focus on two hydrothermal pools, Arkashin Shurf and Zavarzin Spring, in Uzon Caldera, Kamchatka, Russia that were previously characterized using 16S ribosomal RNA sequencing and geochemical analysis undertaken in Burgess et al. 2012 (DOI: 10.1007/s00248-011-9979-4). First we produced metagenomic assembled genomes (MAGs) and then we characterized and compared them between the two pools. Hypotheses: (1) Discussion of MAG's and possible functions; novelty? (2) Comparison of Burgess 16S to metagenomes (3) Differences in functions between pools based on geochemistry.
