This project aims to understand how the deep biosphere obtains phosphorus (P) and impacts sedimentary P cycling by determining the presence or absence of key genes involved in microbial P uptake and metabolism using metagenomic analyses. The proposed work is directly related to C-DEBI central research themes and will greatly enhance our knowledge of the activity in the deep biosphere and the limits of life. Our results will be compared to P geochemical data from North Pond (IODP expedition 336), which involve sequential extractions, stable oxygen isotopes in phosphate (proxy for P cycling) and <sup>31<\/sup>P nuclear magnetic resonance spectroscopy (<sup>31<\/sup>P NMR) data. The combined use of molecular microbial ecology techniques and geochemistry will provide a unique perspective on P sources to the deep biosphere and potential impacts of the deep biosphere on P cycling.<\/p>\n","protected":false},"template":"","meta":[],"award_type":[14],"_links":{"self":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/awards\/494"}],"collection":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/awards"}],"about":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/types\/award"}],"wp:attachment":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/media?parent=494"}],"wp:term":[{"taxonomy":"award_type","embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/award_type?post=494"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
