Processing Description

Raw reads were quality controlled using cutadapt (v1.7.1) and Trimmomatic (v0.33). The QCed sequences were searched for SSU rRNA fragments using Meta-RNA (v.H3). SSU rRNA fragments were assembled using EMIRGE (v.1.3) utilizing SILVA SSU as the reference database using the SINA web portal aligner (Ludwig et al. 2004; Capella-Gutiérrez et al. 2009; Pruesse et al. 2012).


Quibit fluorometer (Thermo Scientific, Waltham, MA, USA) [Fluorometer]

A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.

NanoDrop 1000 Spectrophotometer (Thermo Scientific, Waltham, MA, USA) [Spectrophotometer]

An instrument used to measure the relative absorption of electromagnetic radiation of different wavelengths in the near infra-red, visible and ultraviolet wavebands by samples.

Project Title Potential phosphorus uptake mechanisms of the deep sedimentary biosphere
Acronym Deep sea sediments
Created November 7, 2016
Modified November 7, 2016
Project Description

The goal of this project is to explore potential microbial P uptake mechanisms in marine sediments beneath the North Atlantic Gyre and their effects on the relative distribution of organic P compounds as a function of burial depth and changing redox conditions. We use a combination of metagenomic analyses and solution 31P nuclear magnetic resonance spectroscopy (31P NMR) to investigate (1) the presence of microbial functional genes pertaining to P uptake and metabolism and (2) the possible P substrates for the deep biosphere in these oligotrophic sediments.
