*C-DEBI Contribution 424


Geothermobacter sp. strain HR-1 was isolated from the Lō‘ihi Seamount vent system in the Pacific Ocean at a depth of 1,000 m. Reported here is its 3.84-Mb genome sequence. This research was funded as part of the 2017 NSF Community College Cultivation Cohort (C4) Research Experience for Undergraduates.
 

PNAS
Growth of sedimentary Bathyarchaeota on lignin as an energy source - NEW!
Tiantian Yu, Weichao Wu, Wenyue Liang, Mark Alexander Lever, Kai-Uwe Hinrichs, and Fengping Wang

Members of the archaeal phylum Bathyarchaeota are among the most abundant microorganisms on Earth. Although versatile metabolic capabilities such as acetogenesis, methanogenesis, and fermentation have been suggested for bathyarchaeotal members, no direct confirmation of these metabolic functions has been achieved through growth of Bathyarchaeota in the laboratory. Here we demonstrate, on the basis of gene-copy numbers and probing of archaeal lipids, the growth of Bathyarchaeota subgroup Bathy-8 in enrichments of estuarine sediments with the biopolymer lignin. Other organic substrates (casein, oleic acid, cellulose, and phenol) did not significantly stimulate growth of Bathyarchaeota. Meanwhile, putative bathyarchaeotal tetraether lipids incorporated 13C from 13C-bicarbonate only when added in concert with lignin. Our results are consistent with organoautotrophic growth of a bathyarchaeotal group with lignin as an energy source and bicarbonate as a carbon source and shed light into the cycling of one of Earth’s most abundant biopolymers in anoxic marine sediment.


IODP Workshop Report: Drilling into Young Oceanic Crust for Subseafloor Observations at Axial Seamount - NEW!
Axial Seamount is the most magmatically active submarine volcano in the northeast Pacific and has been the focus of inter-disciplinary studies for over two decades. The range of scientific interests includes volcanology, geophysical characterization and monitoring, hydrothermal vent formation and geochemistry, quantification of heat and chemical fluxes, hydrogeology, and the diversity and evolution of microbiological and animal communities. Axial Seamount erupted in January 1998, April 2011, and April 2015, and is likely to erupt again in the coming years. The site, therefore, presents a unique opportunity to study the interaction between volcanic, hydrothermal, and biological responses to magmatic and volcanic events. Primarily for these reasons, Axial Seamount was chosen as one of the key sites on the National Science Foundations’ (NSF) Ocean Observatories Initiative’s (OOI) cabled observatory network, the Cabled Array (CA). The Axial workshop was held to explore how ocean drilling and related studies can complement seafloor-based investigations by gaining access to the subseafloor to expand our understanding of microbiological, geophysical, hydrologic, and geochemical processes, now that the CA is fully operational with data streaming live to shore from a diverse suite of cabled instruments.

Simons Foundation: In Theaters Now: The Most Unknown - NEW!
Featuring C-DEBI researchers Victoria Orphan and Luke McKay. The Most Unknown is an epic documentary film that sends nine scientists to extraordinary parts of the world to uncover unexpected answers to some of humanity’s biggest questions. How did life begin? What is time? What is consciousness? How much do we really know? By introducing researchers from diverse backgrounds for the first time, then dropping them into new, immersive field work they previously hadn’t tackled, the film pushes the boundaries of how science storytelling is approached. What emerges is a deeply human trip to the foundations of discovery and a powerful reminder that the unanswered questions are the most crucial ones to pose. Directed by Emmy-nominated and Peabody Award-winning filmmaker Ian Cheney (The Search for General TsoThe City Dark) and advised by world-renowned filmmaker Werner Herzog (FitzcarraldoAguirreThe Wrath of GodGrizzly Man), The Most Unknown is an ambitious look at a side of science never before shown on screen. The film was made possible by a grant from Science Sandbox, a Simons Foundation initiative dedicated to engaging everyone with the process of science.
