![Effects of filtration method and sequencing platform on microbial abundance and community composition. Comparison of microbial abundance, sequencing performance, and taxonomic composition among Yellowstone hot spring samples processed using Sterivex, Supor, and polycarbonate (PC) filtration devices and analyzed by Illumina and Oxford Nanopore sequencing. Upper panels show absolute microbial abundance estimates (black bars) and sequence read lengths (red symbols). Lower panels depict species-level relative abundances of dominant bacterial and archaeal (red asterisk) taxa recovered from each sample. -- [biorxiv.org]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Differential-efficiency.png?resize=1200%2C708&ssl=1)
[biorxiv.org] Metagenomic characterization of low-biomass Yellowstone National Park (YNP) hot spring waters remains challenging because microbial recovery is influenced by filtration methodology, sample preservation, DNA extraction, and sequencing strategy.
