Hydrogen limitation and syntrophic growth among natural assemblages of thermophilic methanogens at deep-sea hydrothermal vents
Autor: Begüm D. Topçuoğlu, Lucy C. Stewart, Hilary G Morrison, David A. Butterfield, Julie A Huber, James F. Holden
Publikováno v: Frontiers in Microbiology, Vol 7 (2016)
Thermophilic methanogens are common autotrophs at hydrothermal vents, but their growth constraints and dependence on H2 syntrophy in situ are poorly understood. Between 2012 and 2015, methanogens and H2-producing heterotrophs were detected by growth

Publikováno v: The ISME Journal
The size and biogeochemical impact of the subseafloor biosphere in oceanic crust remain largely unknown due to sampling limitations. We used reactive transport modeling to estimate the size of the subseafloor methanogen population, volume of crust oc

Diverse microbial communities drive biogeochemical cycles in Earth’s ocean, yet studying these organisms and processes is often limited by technological capabilities, especially in the deep ocean. In this study, we used a novel marine microbial inc

Significance Much of Earth’s volcanism occurs in the deep sea, yet little is known about the microbial communities inhabiting such extreme and dynamic systems. Using a multidisciplinary approach to study distinct hydrothermal systems at Brothers su

Temperature-gradient incubation isolates multiple competitive species from a single environmental sample
Autor: Lucy C. Stewart, Karen M. Houghton
Publikováno v: Access Microbiology
High-throughput sequencing has allowed culture-independent investigation into a wide variety of microbiomes, but sequencing studies still require axenic culture experiments to determine ecological roles, confirm functional predictions and identify us

Experimental investigation on the controls of clumped isotopologue and hydrogen isotope ratios in microbial methane
Autor: Begüm D. Topçuoğlu, Shuhei Ono, Martin Könneke, James F. Holden, Tobias Goldhammer, Lucy C. Stewart, David T. Wang, Danielle S. Gruen, Kai-Uwe Hinrichs
Publikováno v: Geochimica et Cosmochimica Acta. 237:339-356
The abundance of methane isotopologues with two rare isotopes (e.g., 13CH3D) has been proposed as a tool to estimate the temperature at which methane is formed or thermally equilibrated. It has been shown, however, that microbial methane from surface
