Autochthonous bioaugmentation with non-direct degraders: A new strategy to enhance wastewater bioremediation performance

Environment International, 2020
Autochthonous bioaugmentation (ABA) strategies are primarily carried out using a single, highly efficient type of bacteria that is capable of directly degrading the target compound. However, no studies have examined the use of non-direct degraders (NDDs),

Multisubstrate Isotope Labeling and Metagenomic Analysis of Active Soil Bacterial Communities

mBio, 2014
Soil microbial diversity represents the largest global reservoir of novel microorganisms and enzymes. In this study, we coupled functional metagenomics and DNA stable-isotope probing (DNA-SIP) using multiple plant-derived carbon substrates and diverse ...

Bacterial metabolism of methylated amines and identification of novel methylotrophs in Movile Cave [PDF]

, 2015
Movile Cave, Romania, is an unusual underground ecosystem that has been sealed off from the outside world for several million years and is sustained by non-phototrophic carbon fixation. Methane and sulfur-oxidising bacteria are the main primary producers,

Diversity of isoprene-degrading bacteria in phyllosphere and soil communities from a high isoprene-emitting environment: a Malaysian oil palm plantation

Microbiome, 2020
Background Isoprene is the most abundantly produced biogenic volatile organic compound (BVOC) on Earth, with annual global emissions almost equal to those of methane.

Isoprene-degrading bacteria associated with the phyllosphere of Salix fragilis, a high isoprene-emitting willow of the Northern Hemisphere

Environmental Microbiome, 2021
Background Isoprene accounts for about half of total biogenic volatile organic compound emissions globally, and as a climate active gas it plays a significant and varied role in atmospheric chemistry. Terrestrial plants are the largest source of isoprene,

Methanotrophy Alleviates Nitrogen Constraint of Carbon Turnover by Rice Root-Associated Microbiomes

Frontiers in Microbiology, 2022
The bioavailability of nitrogen constrains primary productivity, and ecosystem stoichiometry implies stimulation of N2 fixation in association with carbon sequestration in hotspots such as paddy soils.

A culture-independent approach to unravel uncultured bacteria and functional genes in a complex microbial community [PDF]

, 2012
Most microorganisms in nature are uncultured with unknown functionality. Sequence-based metagenomics alone answers 'who/what are there?' but not 'what are they doing and who is doing it and how?'.

Ultra-sensitive isotope probing to quantify activity and substrate assimilation in microbiomes

Microbiome, 2023
Background Stable isotope probing (SIP) approaches are a critical tool in microbiome research to determine associations between species and substrates, as well as the activity of species. The application of these approaches ranges from studying microbial
