Jun 26, New preprint on a novel class of methanogens is out! Anthony and Sylvia cultured and characterized Methanonezhaarchaeia, the third class of methanogens within the phylum Thermoproteota Preprint PDF
Jun 13, Nicole receives award, Joelie receives honorable mention from the NSF GRFP! They will work on methanogens within the Methanosuratincola in diverse ecosystems.
May 30, New paper out in Microbiology Spectrum: A comparative analysis of stable isotope probing using correlative Raman microspectroscopy and Nano-scale secondary ion mass spectrometry measurements on the same E. coli cells to establish the extent of data equivalence between the two methods. Congrats George! PDF
May 1, Congratulations to Jacob for receiving a 1-year TL1 training award by the Institute of Translational Health Sciences.
Oct 1 2024, The lab is awarded a $1M grant by the DOE BER and EPSCoR programs to study Methanosuratincola in diverse anoxic ecosystems. Our research will take us from hot springs to soil, from waste water to rumen, from marine sediments to bioreactors. The grant will fund the PhDs of Joelie and Nicole as well as the work of staff scientist Zack Jay.
This study describes the cultivation and physiology of a thermophilic methanol-reducing methanogen affiliated with the archaeal class Korarchaeia. Together with our other publication (see below) this study shows that methanogenesis is not restricted to the superphylum Euryarchaeota. The latter had been known to host all methanogens since the discovery of the archaeal domain by Carl Woese in the 1970ies.

This study demonstrates, for the first time, that methanogenesis is not confined to the Euryarchaeota. Anthony cultured a thermophilic archaeon from the phylum Thermoproteota (TACK superphylum) from a Yellowstone hot spring and demonstrated that it is a bona fide methanogen. CryoET work with the lab of Martin Pilhofer revealed the methanogen's unique ultrastructure, including cell-to-cell bridges through which cells share their cytoplasm.

Jul 20 2024, Out in PLoS Biology: George's Opus Magnum Multicellular magnetotactic bacterial consortia are metabolically differentiated and not clonal. We studied the unique biology of multicellular magnetotactic bacteria, the only example of bacteria without a unicellular stage in their life cycle! Editor' Choice Paper for 2024 PDF
Mar 19 2024, Out in The ISME J: Methylotrophic methanogenesis in the Archaeoglobi: Cultivation of Ca. Methanoglobus hypatiae from a Yellowstone hot spring. Congrats Mack on a great piece of work that combines targeted cultivation, growth experiments, fluorescence and electron microscopy, stable isotope tracing, metagenomics, and metatranscriptomics! PDF
Hatzenpichler Environmental Microbiology Lab
99% of microbes currently cannot be grown in the lab. We seek to understand what this "uncultured majority" is doing and how its activity shapes Earth's biogeochemical cycles and life on our planet.
