The U.S. Desert Southwest hosts a variety of unusual and little-characterized microbial habitats. Among these are Death Valley - officially the hottest place on Earth - and the Nevada National Security Site (NNSS), where 828 underground tests of cold war nuclear devices were conducted. Above and below ground, with or without oxygen, high salinity or freshwater, with limited carbon resources and extreme heat these environments support a diverse array of microbes. In most cases extensive explorations of microbial diversity have not been performed, particularly among desert subsurface microorganisms. If we consider only 0.1% of ecological microbes are amenable to laboratory cultivation, a substantial majority of microbial life remains potentially available for even the most basic of characterizations. In this study, we enriched and isolated microbes from several desert subsurface habitats and from a hypersaline playa. Subsurface water samples were collected from wells drilled as part of the Underground Test Area (UGTA) program. These wells penetrate distinct lithological units including high elevation volcanics (ER 20-4, ER 20-8, ER EC-13), valley fill alluvium (ER 5-5), and the regional carbonate aquifer (U-3cn PS#2/”Bilby” at the NNSS) and (BLM-1 and Nevares Deep Well #2 in or near Death Valley). Well depths range from 309-610m. Water samples were used to inoculate enrichment media supporting anaerobic sulfate/sulfur reduction, anaerobic peptide/sugar fermentation, simple short chain fatty acid fermentation, iron/manganese reduction, or anaerobic methanotrophy. The decision to try these metabolic conditions was supported by geochemical data. Enrichments resulted in growth in two-thirds of conditions tried on the Nevares DW#2 sample, and a quarter of conditions on the UE-3cn “Bilby” sample. The reduction of Mn(IV) oxides was tested on all wells, and only resulted in growth from Nevares DW#2. Although several conditions resulted in dense growth, only three bacterial isolates were obtained in pure culture to date. On anaerobic manganese reduction medium, the Nevares DW#2 well generated an isolate belonging to the genus Desulfotomaculum. The U-3cm PS#2 Bilby well produced two isolates: one on anaerobic proteolytic conditions, belonging to the family Peptococcacae, and another on anaerobic methane medium, belonging to the genus Desulforudis. The U-3cn PS#2/Bilby microbe isolated from the methane medium preparation is of special interest. To date, the Desulforudis genus has only been detected in limited terrestrial and marine deep subsurface habitats and has yet to produce a cultivated representative. The D. audaxviator from African deep mines is currently the only microorganism known with the capacity to exist as a single-species ecosystem, to grow completely isolated from the photosphere (e.g. utilizing radiochemically-produced H2 and SO42-), and is arguably Earth’s deepest known life form.


Each room is equipped with an internet connected computer (equipped with USB port for flash drive connection) with projection system. Speakers will be allowed 15 minutes to present their talks. Further information can be provided by the session chairs listed below.

A good poster is uncluttered and clear in design. It has legible text and logical organization. The main tenet of a good poster design is simplification. Use a crisp, clean design and a strong title. Do not tell the entire research history; present only enough data to support your conclusions and show the originality of the work.

The text material should be reduced to convey your points quickly and clearly. The most successful posters display a succinct statement of major conclusions at the beginning, followed by supporting text in later segments, and a brief summary at the end.

Design Suggestions

  • Allow ample time, at least several weeks, to prepare your posters.
    All lettering should be legible from about 5 feet (1.5 m) away.
    Text material should be approximately 24 points (¼”, 0.625 cm).
  • Mounting space will be available for posters. Please bring push or T pins for mounting. Wall space is somewhat limited so please economize on your poster size and your use of the available space. (Don't be a "display hog.")
  • Be sure to pack whatever you need to display your poster (e.g., tape). All mounting material must be removed when you take your poster down.
  • All posters should feature a title, your name, the name of the institution where the research was performed, and should credit persons who have helped you with your research.


  1. The top of the board should consist of an easy-to-read title that includes the author(s) name(s). The title lettering should be about 2" to 3" (5 cm to 7.5 cm) with subheadings 1/2" to 1" high (1.25 cm to 2.5 cm).
  2. All lettering should be legible from 5 feet (1.5m) away. The minimum type size for text should be no less than 18 points, but 24 points (1/4", 0.625 cm) is preferable.
  3. The component parts should be organized in a way that leads the viewer through the display.
  4. Leave some open space in the design.
  5. Use elements of different size and proportions. Convert tabular material to graphic display, if possible.
  6. A larger and /or bright center of interest can draw the eye to the most important aspect of the poster. Use color to add emphasis and clarity.
  7. Make illustrations simple and bold. Enlarge photos to show pertinent details clearly.
  8. Displayed materials should be self-explanatory, freeing you for discussion.
  9. No demonstration experiments or three-dimensional displays (other than tri-fold poster boards) are allowed in a poster session.

Poster Presentation

  1. Tape will be available in the poster area on a first-come, first serve basis. We recommend that you bring your own to ensure availability. All mounting material must be removable without marring the surface and must be removed when you take your poster down.
  2. All posters must be set up in the time allotted before the session, and must remain up until the session ends. All posters must be taken down at the conclusion of the poster session. Do not leave any materials, tape, trash, etc. in your poster area.
  3. During the time your work is displayed, you must be present by your poster to discuss your paper.

Best Student Paper/Poster Awards

Students are encouraged to apply for awards in presentation of posters or presentations. Both ANAS and the Arizona / Southern Nevada Chapter of ASM will be providing awards.

Undergraduate or gradate students wishing to participate in the Best Student Presentation competition must follow all the directions above for "Instructions to Authors" as well as meet the requirements below:

  1. Place an asterisk (*) at the beginning of the title of the abstract.
  2. Abstracts to be considered for this award may be co-authored by the student and their major professor. The student MUST, however, be listed as the first author, and their name underlined to indicate they are the presenter.
  3. Entrants not meeting ALL of these requirements will be not be considered for the award.
