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
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]
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,

Identification of active aerobic methanotrophs in plateau wetlands using DNA stable isotope probing [PDF]
Sedge-dominated wetlands on the Qinghai-Tibetan Plateau are methane emission centers. Methanotrophs at these sites play a role in reducing methane emissions, but relatively little is known about the composition of active methanotrophs in these wetlands.

Identification of critical members in a sulfidogenic benzene-degrading consortium by DNA stable isotope probing. [PDF]
ABSTRACTStable isotope probing (SIP) was used to identify the active members in a benzene-degrading sulfidogenic consortium. SIP-terminal restriction fragment length polymorphism analysis indicated that a 270-bp peak incorporated the majority of the13C label and is a sequence closely related to that of clone SB-21 (GenBank accession no. AF029045). This

Nutrient Amendments in Soil DNA Stable Isotope Probing Experiments Reduce the Observed Methanotroph Diversity [PDF]
ABSTRACT Stable isotope probing (SIP) can be used to analyze the active bacterial populations involved in a process by incorporating 13 C-labeled substrate into cellular components such as DNA. Relatively long incubation times are often used with laboratory microcosms in order to incorporate sufficient

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