摘要

The Hawaiian Islands are among the most geologically and volcanically active places on Earth. While the Hawaiian Archipelago is known for its animal and plant diversity, much less is known about microbial diversity in the area’s diverse habitats. In this study, we focused on steam vent associated biofilms found on the most volcanically active island of Hawaiʻi, also known as the Big Island. From 46 samples from various biofilms and associated features around fumaroles emitting water steam, we generated amplicon and metagenomic sequences. This represents a total of 276 Gbp of raw sequencing data. From the shotgun metagenomic data, we constructed 363 non-redundant medium- to high-quality metagenome-assembled genomes (MAGs) that are at least 70% complete and with less than 5% contamination. Of these, ten MAGs belong in the domain Archaea, and 353 belong in the domain Bacteria. This dataset could provide valuable insights into microbial diversity and ecology around volcanic features in Hawai’i and elsewhere.
