Hot Off the Press: Marine sediments microbes capable of electrode oxidation as a surrogate for lithotrophic insoluble substrate metabolism (C-DEBI Contribution 255) in Frontiers in Microbiology
Little is known about the importance and/or mechanisms of biological mineral oxidation in sediments, partially due to the difficulties associated with culturing mineral-oxidizing microbes. C-DEBI Postdoctoral Fellow Rowe et al. demonstrate that electrochemical enrichment is a feasible approach for isolation of microbes capable of gaining electrons from insoluble minerals. To this end we constructed sediment microcosms and incubated electrodes at various controlled redox potentials. Negative current production was observed in incubations and increased as redox potential decreased (tested -50 to -400 mV vs Ag/AgCl). Electrode-associated biomass responded to the addition of nitrate and ferric iron as terminal electron acceptors in secondary sediment-free enrichments. Elemental sulfur, elemental iron and amorphous iron sulfide enrichments derived from electrode biomass demonstrated products indicative of sulfur or iron oxidation. The microbes isolated from these enrichments belong to the genera Halomonas, Idiomarina, Marinobacter, and Pseudomonas of the Gammaproteobacteria, and Thalassospira and Thioclava from the Alphaproteobacteria. Chronoamperometry data demonstrates sustained electrode oxidation from these isolates in the absence of alternate electron sources. Cyclic voltammetry demonstrated the variability in dominant electron transfer modes or interactions with electrodes (i.e., biofilm, planktonic or mediator facilitated) and the wide range of midpoint potentials observed for each microbe (from 8 to -295 mV vs. Ag/AgCl). The diversity of extracellular electron transfer mechanisms observed in one sediment and one redox condition, illustrates the potential importance and abundance of these interactions. This approach has promise for increasing our understanding the extent and diversity of microbe mineral interactions, as well as increasing the repository of microbes available for electrochemical applications.

Hot Off the Press: Earth and Life Processes Discovered from Subseafloor Environments, 1st Edition: A Decade of Science Achieved by the Integrated Ocean Drilling Program (IODP), R. Stein, D. Blackman, F. Inagaki and H.-C. Larsen (Eds.), Series: Developments in Marine Geology, Elsevier
The Integrated Ocean Drilling Program (IODP: 2000-2013) has provided crucial records of past and present processes and interactions within and between the biosphere, cryosphere, atmosphere, hydrosphere and geosphere. Research in IODP encompasses a wide range of fundamental and applied issues that affect society, such as global climate change, biodiversity, the origin of life, natural hazards involving the study of earthquakes processes, and the internal structure and dynamics of our planet. This compilation of major findings from the 2003-2013/14 phase of IODP, focusing on scientific results rather than description of data acquisition and early inferences, provides invaluable information. Anyone wondering what scientific drilling can achieve will gain quick understanding of the range of questions that are uniquely addressed with this methodology and the ways these data dovetail with other regional information. The excitement of breakthrough findings that occasionally accompanies a drilling project will be evident. IODP obtained unique records from the global ocean basins during the 2003-2013 program phase. This book highlights findings in three theme areas: Subseafloor life and the marine biosphere; Earth's changing environments; and Dynamics of the solid Earth. Each core or borehole log provides a window revealing insights that no other data achieve.

Dorado Outcrop: AT26-24 with the Submersible Alvin, November 30 - December 12, 2014, Expedition Report
AT26-24 was the second of two cruises that focused on Dorado Seamount. The first expedition occurred in December 2013 and utilized the remotely operated vehicle (ROV) Jason and the autonomous underwater vehicle (AUV) Sentry. These two assets allowed us to collect bathymetric, backscatter, side-scan, images, magnetometer, and thermal anomaly data. They also provided targets for closer inspection of the seafloor that led to the discovery of warm springs on the seafloor. In 2013 we sampled these springs with the ROV Jason, collected rock and sediment push cores, and made measurements of heat flow. We also deployed temperature loggers, OsmoSamplers, which are continuous fluid sampling devices, and enrichment experiments in several springs to asses the temporal variability in thermal and chemical signatures and to asses the rate of enrichment on particular substrates in this environment. These springs were the focus of the dive program (AT26-24) in December 2014 that utilized the submersible Alvin. We completed ten Alvin dives, collected thirteen gravity cores, conducted one CTD hydrocast, and completed four surveys using the hull-mounted bathymetric mapping system. Through these activities we collected hundreds of samples for hydrologic, biogeochemical, and microbial studies, all of which will continue ashore with a spectrum of analytical techniques and modeling efforts.


Education & Outreach

Stanford: Hopkins Microbiology Course, June 19 - July 18
The Hopkins Microbiology Course offers:

  • Four weeks of intense learning activity focused on microbes and microbial life. Our approach is integrative, holistic and concept based. The study of microbes is placed firmly within the physiological, ecological (biogeochemical), genetic and evolutionary framework.
  • Exposure to a wealth of new ideas and concepts. Dedicated faculty and experienced teaching assistants are continuously on hand to offer guidance and expertise
  • Seminars ranging from the factual to the philosophical.  Practical work forms a large part of the course and provides students with hands-on experience in isolation of a wide range of microbes, experimental evolution, population genetics, clone library construction, and bioinformatic analysis. The course experiments are not “canned” and you will make new discoveries.

By the end of the course you will have a broad, fundamental understanding of the key concepts of microbial life and how they interconnect to each other. In addition you will have a solid set of experimental tools that enables you to address contemporary questions in microbial biology. Is this the course for you? The HMC is more than an introduction to microbiology: the course provides a factual background in key aspects of microbial biology, but, in keeping in the tradition of van Niel’s teaching, there is a strong emphasis on concepts, ideas, questions and the placement of microbiological knowledge within a broader and more mainstream context.  A background in microbiology is not essential, but it is an advantage. Important is a mature approach to learning and a desire to go beyond the undergraduate lecture theatre environment. Application deadline: March 1, 2015.

Proposal Calls

NSF: Dimensions of Biodiversity Program Solicitation
Despite centuries of discovery, most of our planet's biodiversity remains unknown. The scale of the unknown diversity on Earth is especially troubling given the rapid and permanent loss of biodiversity across the globe. The goal of the Dimensions of Biodiversity campaign is to transform, by 2020, how we describe and understand the scope and role of life on Earth. This campaign promotes novel integrative approaches to fill the most substantial gaps in our understanding of the diversity of life on Earth. It takes a broad view of biodiversity, and focuses on the intersection of genetic, phylogenetic, and functional dimensions of biodiversity. Successful proposals must integrate these three dimensions to understand interactions and feedbacks among them. While this focus complements several core programs in BIO and GEO, it differs by requiring that multiple dimensions of biodiversity be addressed simultaneously, in novel ways, to understand their synergistic roles in critical ecological and evolutionary processes. The Dimensions of Biodiversity program again includes partnerships with the National Natural Science Foundation of China (NSFC) and São Paulo Research Foundation (FAPESP) of Brazil in fiscal year 2015. Investigators wishing to inquire about the suitability of potential projects for Dimensions of Biodiversity are encouraged to email a brief summary and contact information to Dimensions@nsf.gov. Full proposal deadline: April 09, 2015.
