Lipid Analysis of CO2-Rich Subsurface Aquifers Suggests an Autotrophy-Based Deep Biosphere with Lysolipids Enriched in CPR Bacteria

Banfield Received: 20 November 2018 / Revised: 5 February 2020 / Accepted: 25 February 2020 / Published online: 13 March 2020 © The Author(s) 2020. This article is published with open access Abstract Sediment-hosted CO2-rich aquifers deep below the Colorado Plateau (USA) contain a remarkable diversity of uncultivated microorganisms, including Candidate Phyla Radiation (CPR) bacteria that are putative symbionts unable to synthesize membrane lipids. The origin of organic carbon in these ecosystems is unknown and the source of CPR membrane lipids remains elusive. We collected cells from deep groundwater brought to the surface by eruptions of Crystal Geyser, sequenced 1234567890();,: 1234567890();,: the community, and analyzed the whole community lipidome over time. Characteristic stable carbon isotopic compositions of microbial lipids suggest that bacterial and archaeal CO2 fixation ongoing in the deep subsurface provides organic carbon for the complex communities that reside there. Coupled lipidomic-metagenomic analysis indicates that CPR bacteria lack complete lipid biosynthesis pathways but still possess regular lipid membranes. These lipids may therefore originate from other community members, which also adapt to high in situ pressure by increasing fatty acid unsaturation. -

Spera __________________________________________ Matthew G. Jackson __________________________________________ Roberta L. Rudnick, Committee Chair December 2018 ACKNOWLEDGEMENTS I dedicate this dissertation to my mom and dad, Melissa Talbott and Dennis Greaney, who instilled a sense of curiosity and independence in me from an early age. From talking me through my first elementary school homework assignments that left me in tears, to sharing words of encouragement when grad school finances got tight (“When I was in grad school I just shared peanut butter with the dog at the end of the month when I ran out of money”), my mom and dad taught me the persistence and resilience needed to be successful in a PhD program. They have shaped me into the person I am today, and I truly could not have gotten to where I am without them. Similarly, I’ve treasured the support and comedic relief from my sister Sam throughout the years. -

Nature and Extent of the Deep Biosphere Frederick S
Reviews in Mineralogy & Geochemistry Vol. 75 pp. 547-574, 2013 17 Copyright © Mineralogical Society of America Nature and Extent of the Deep Biosphere Frederick S. Colwell College of Earth, Ocean, and Atmospheric Sciences Oregon State University Corvallis, Oregon 97331-5503, U.S.A. [email protected] Steven D’Hondt Graduate School of Oceanography University of Rhode Island Narragansett, Rhode Island 02882, U.S.A. [email protected] INTRODUCTION In the last three decades we have learned a great deal about microbes in subsurface envi- ronments. Once, these habitats were rarely examined, perhaps because so much of the life that we are concerned with exists at the surface and seems to pace its metabolic and evolutionary rhythms with the overt planetary, solar, and lunar cycles that dictate our own lives. And it cer- tainly remains easier to identify with living beings that are in our midst, most obviously strug- gling with us or against us for survival over time scales that are easiest to track using diurnal, monthly or annual periods. Yet, research efforts are drawn again and again to the subsurface to consider life there. No doubt this has been due to our parochial interests in the resources that exist there (the water, minerals, and energy) that our society continues to require and that in some cases are created or modified by microbes. However, we also continue to be intrigued by the scientific curiosities that might only be solved by going underground and examining life where it does and does not exist. But really, is life underground just a peculiarity of most life on the planet and only a re- cently discovered figment of life? Or is it actually a more prominent and fundamental, if unseen, theme for life on our planet? Our primary purpose in this chapter is to provide an incremental assembly of knowledge of subsurface life with the aim of moving us towards a more complete conceptual model of deep life on the planet. -

The Taylor Colloquium: an Introduction Scorr M. ~CLENNAN' and ROBERTA L, RUDNICK

The Taylor Colloquium: An introduction Scorr M. ~CLENNAN’ and ROBERTA L, RUDNICK~ ‘Department of Earth and Space Sciences, State University of New York at Stony Brook, Stony Brook, NY 11794-2100, USA ‘Research School of Earth Sciences. Australian National University, Canberra, ACT 2601, Australia Ross TAYLOR HAS been a preeminent geochemist for more than thirty-five years. For the past thirty years, he has been a dominating force in the field of trace element geochemistry. The year 1990 was an important benchmark for Ross on a number of counts. He celebrated his sixty-fifth birthday, and accordingIy it marked his retirement as Professorial Fellow from the Research School of Earth Sciences (RSES ) at The Australian National University. (He has now taken up resi- dence across the road in the Research School of Physical Sciences.) In recognition, The Taylor Colloquium was held at RSES, in Canberra, on October l-2,1990. It was sponsored jointly by the International Union of Geological Sciences, The Geochemical Society, the Australian Academy of Sci- ences, and RSES. The meeting was organized by Roberta Rudnick, Malcolm McCulloch, and Dick Price in Canberra and by Scott McLennan in Stony Brook. More than fifty scientists from nine countries were in attendance, representing colleagues, friends, and former students. Trying to develop a colloquium theme to reflect a career that has covered as much ground as that of Ross’s was no mean feat. The “Origin and Evolution of Planetary Crusts” was finally selected as a subject that transgresses Ross’s major research interests in the Earth, Moon, and other planets of the solar system. -
Commodore of a Global DNA Census
Commodore of a Global DNA Census Tue Apr 26 2011 Page: D1 / Science Times Byline: NICHOLAS WADE Column: SCIENTIST AT WORK JESSE H. AUSUBEL Length: 1,704 words Ad Value: $940,680 Circulation: 1,126,190 "Dinochelus ausubeli" was the name conferred earlier this year on a strange deep sea monster, a lobster discovered off the Philippine coast whose right claw is elongated into a fearsome pincer. The new species was named not after its discoverer, but in honor of the person under whose auspices a fleet of 540 ships from 80 nations has found the lobster and 6,000 other new marine species in the last 10 years. He is Jesse H. Ausubel, a Rockefeller University environmental researcher who is also vice president of the Alfred P. Sloan Foundation of New York. With his academic hat, Mr. Ausubel, 59, writes and thinks about the environment. Under his foundation hat, he has so far started four major international programs to survey the planet and catalog its biological diversity. He began the Census of Marine Life in 2000 after discussions with Fred Grassle, a deep-sea biologist at Rutgers University. The project began as a census of the fishes, but as more biologists got involved it expanded to include invertebrates, a wide range of habitats from shoreline to the ocean abysses, and a system for monitoring the distribution of ocean species. The Sloan Foundation invested $75 million in the census, but all the ship time was paid for by the participating institutions. By the time the first census finished, in 2010, total investment in the project had reached $650 million. -
