DNA-stable isotope probing (DNA-SIP) identifies marine sponge-associated bacteria actively utilizing dissolved organic matter (DOM). [PDF]

Environ Microbiol, 2021
Summary Sponges possess exceptionally diverse associated microbial communities and play a major role in (re)cycling of dissolved organic matter (DOM) in marine ecosystems. Linking sponge‐associated community structure with DOM utilization is essential to understand host–microbe interactions in the uptake ...

Unearthing the Ecology of Soil Microorganisms Using a High Resolution DNA-SIP Approach to Explore Cellulose and Xylose Metabolism in Soil [PDF]

Frontiers in Microbiology, 2016
We explored microbial contributions to decomposition using a sophisticated approach to DNA Stable Isotope Probing (SIP). Our experiment evaluated the dynamics and ecological characteristics of functionally defined microbial groups that metabolize labile and structural C in soils.

¹³C-DNA-SIP distinguishes the prokaryotic community that metabolizes soybean residues produced under different CO₂ concentrations

, 2019
© 2019 Wang, Yu, Li, Wang, Tang, Liu, Liu, Xie and Jin. The amendment of crop residues produced under elevated CO2 (eCO2) may alter soil microbial community structure and their functions on residue decomposition and carbon (C) cycling in soil. The key to understanding this process is to elucidate the structure of prokaryotic communities that metabolize

DNA-SIP delineates unique microbial communities in the rhizosphere of the hyperaccumulator Sedum alfredii which are beneficial to Cd phytoextraction

Ecotoxicology and Environmental Safety
Rhizo-microbe recruited by hyperaccumulating plants are crucial for the extraction of metals from contaminated soils. It is important, but difficult, to identify the specific rhizosphere microbes of hyperaccumulators shaped by root exudation.

Bacteria responsible for antimonite oxidation in antimony-contaminated soil revealed by DNA-SIP coupled to metagenomics [PDF]

FEMS Microbiology Ecology, 2021
ABSTRACT Antimony (Sb), the analog of arsenic (As), is a toxic metalloid that poses risks to the environment and human health. Antimonite (Sb(III)) oxidation can decrease Sb toxicity, which contributes to the bioremediation of Sb contamination.

Syntrophic interactions driving anaerobic methane oxidation in deep-sea cold seeps revealed by DNA-SIP. [PDF]

iScience
Anaerobic oxidation of methane is a key process reducing methane emissions in oxygen-depleted marine environments such as deep-sea cold seeps. However, the stability and adaptability of microbial interactions driving this process remain poorly understood. Here, we combined stable isotope probing, tracer incubations, and bacterial inhibition experiments

Methanotrophic Community Detected by DNA-SIP at Bertioga’s Mangrove Area, Southeast Brazil [PDF]

Microbial Ecology, 2020
Abstract Methanotrophic bacteria can use methane as sole carbon and energy source. Its importance in the environment is related to the mitigation of methane emissions from soil and water to the atmosphere. Brazilian mangroves are highly productive, have potential to methane production, and it is inferred that methanotrophic community is

DNA stable-isotope probing (DNA-SIP). [PDF]

J Vis Exp, 2010
DNA stable-isotope probing (DNA-SIP) is a powerful technique for identifying active microorganisms that assimilate particular carbon substrates and nutrients into cellular biomass. As such, this cultivation-independent technique has been an important methodology for assigning metabolic function to the diverse communities inhabiting a wide range of ...
