2019 journal article

Determinants of sulphur chemolithoautotrophy in the extremely thermoacidophilic Sulfolobales

ENVIRONMENTAL MICROBIOLOGY, 21(10), 3696–3710.

By: B. Zeldes n, A. Loder, J. Counts n, M. Haque n, K. Widney n, L. Keller n, S. Albers*, R. Kelly n

MeSH headings : Autotrophic Processes; Chemoautotrophic Growth; Oxidation-Reduction; Oxidoreductases / metabolism; Sulfolobales / metabolism; Sulfur / metabolism; Thiosulfates / metabolism
TL;DR: Comparative transcriptomic analyses of Acidianus brierleyi, a chemolithoautotrophic sulfur oxidizer, and S. acidocaldarius DSM639 showed that while both share a strong transcriptional response to elemental sulfur, both failed to up-regulate key 3-HP/4-HB cycle genes used by A. briersleyi to drive chemolithOautotrophy.
