|C-DEBI Newsletter – November 2, 2015
This newsletter is also accessible via our website.
Congratulations to Dr. William Orsi who has accepted a faculty position at the University of Munich (LMU) Department of Palaeontology & Geobiology and will be part of the “GeoBio Center“! Bill has been involved with C-DEBI as a research grantee and postdoctoral fellow while at the Woods Hole Oceanographic Institute and University of Maryland Horn Point Laboratory. See his contributed publications here!
He also wanted to share the International Master’s program “Geobiology and Paleobiology” (MGAP) that is run out of his new department: a consecutive, research-oriented, four-term international master program of the Faculty of Geosciences, Ludwig-Maximilians-Universität München, in collaboration with researchers of the Bavarian State collections under the umbrella of the GeoBio-Center LMU.
Congratulations also to Dr. Julie Meyer, recently awarded a 2015 L’Oréal USA For Women in Science Fellowship at the National Museum of Women in the Arts in Washington, D.C.! Julie was a C-DEBI postdoctoral fellow while at Marine Biological Laboratory, and currently studies the role of microbial interactions in the health and stability of coral reefs. The fellowship will support the further development of Meyer’s research including the sequencing of whole genomes, as well as to produce a short documentary film highlighting the work of women in coral reef research.

Deep continental subsurface fracture water systems, ranging from 1.1 to 3.3 kilometers below land surface (kmbls), were investigated to characterize the indigenous microorganisms and elucidate microbial carbon sources and their cycling. Analysis of phospholipid fatty acid (PLFA) abundances and direct cell counts detected varying biomass among sites that was not correlated with depth. Compound-specific carbon isotope analyses (δ13C and Δ14C) of the phospholipid fatty acids (PLFAs) and carbon substrates combined with genomic analyses did identify, however, distinct carbon sources and cycles between the two depth ranges studied. In the shallower boreholes at circa 1 kmbls, isotopic evidence indicated microbial incorporation of biogenic CH4 by the in situ microbial community. At the shallowest site, 1.05 kmbls in Driefontein mine, this process clearly dominated the isotopic signal. At slightly deeper depths, 1.34 kmbls in Beatrix mine, the isotopic data indicated the incorporation of both biogenic CH4 and dissolved inorganic carbon (DIC) derived from CH4 oxidation. In both of these cases, molecular genetic analysis indicated that methanogenic and methanotrophic organisms together comprised a small component (<5%) of the microbial community. Thus, it appears that a relatively minor component of the prokaryotic community is supporting a much larger overall bacterial community in these samples. In the samples collected from > 3 kmbls in Tau Tona mine (TT107, TT109 Bh2), the CH4 had an isotopic signature suggesting a predominantly abiogenic origin with minor inputs from microbial methanogenesis. In these samples, the isotopic enrichments (δ13C and Δ14C) of the PLFAs relative to CH4 were consistent with little incorporation of CH4 into the biomass. The most 13C-enriched PLFAs were observed in TT107 where the dominant CO2-fixation pathway was the acetyl-CoA pathway by non-acetogenic bacteria. The differences in the δ13C of the PLFAs and the DIC and DOC for TT109 Bh2 were ∼-24‰ and 0‰, respectively. The dominant CO2-fixation pathways were 3-HP/4-HB cycle > acetyl-CoA pathway > reductive pentose phosphate cycle.

UNOLS: 2016 Chief Scientist Workshop Aboard the R/V Thompson
We are pleased to announce a Chief Scientist Training Cruise Opportunity that will take place in February 2016 aboard the R/V Thomas G Thompson. Please share with your colleagues and anyone else you think might be interested! This cruise, a 2 day pre-cruise informational workshop, and phone conferences planning sessions, will instruct early career marine scientists, including PhD students, postdocs and faculty, on how to effectively plan for, acquire, utilize, and report on time at sea for multi-disciplinary research and education. This 2016 Chief scientist program will be staged from San Diego and will include a 7 day research cruise aboard the R/V Thomas G. Thompson in coastal and offshore waters. It will take place between 11 February and 20 February 2016. Small stipends are provided for participant travel costs, research supplies, and shipping. Space is limited. To apply you must be an employee or student (U.S. Citizen or permanent resident) at a U.S. institution or a U.S. citizen working abroad. To be considered, applications must be received by November 30, 2015.

BISAL: Biology and Planetary Exploration in the Deep Subsurface – Call for Experiments
The Boulby International Subsurface Astrobiology Laboratory (BISAL) is part of the Boulby Underground Laboratory, an STFC-funded deep underground science facility operating in Boulby Potash and salt mine in the northeast UK. The environment of the mine is a 250 million year old sequence of salts laid down in the Permian. Located at 1.1 km depth, the BISAL lab and supported access to the wider mine environment offers opportunity for a wide diversity of experiments including studies of biology at below background levels of radiation, life in deep subsurface environments, studies of deep subsurface biogeochemical cycling and deep carbon. The lab is also used as an environment for the testing of instrumentation for use in planetary exploration (MINAR – Mine Analog Research) and particularly technology that has potential for transfer into the mining sector. A dedicated ‘Mars-yard’ area allows for testing of instruments and robotics. The BISAL lab currently being expanded an improved as part of a recent £1.7 million upgrade to the Boulby Underground Laboratory infrastructure. This is a call for experiments wishing to use the BISAL facility. Experiments that cover any area of deep surface biology and astrobiology or planetary exploration are of potential interest.
