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

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),

SIP metagenomics identifies uncultivated Methylophilaceae as dimethylsulphide degrading bacteria in soil and lake sediment [PDF]

, 2015
Dimethylsulphide (DMS) has an important role in the global sulphur cycle and atmospheric chemistry. Microorganisms using DMS as sole carbon, sulphur or energy source, contribute to the cycling of DMS in a wide variety of ecosystems.

Using formalin fixed paraffin embedded tissue to characterize the preterm gut microbiota in necrotising enterocolitis and spontaneous isolated perforation using marginal and diseased tissue

BMC Microbiology, 2019
Background Necrotising enterocolitis (NEC) is a common cause of death in preterm infants and is closely linked to the gut microbiota. Spontaneous intestinal perforation (SIP) also occurs in preterm neonates, but results in lower mortality and less ...

Novel Isoprene-Degrading Proteobacteria From Soil and Leaves Identified by Cultivation and Metagenomics Analysis of Stable Isotope Probing Experiments

Frontiers in Microbiology, 2019
Isoprene is a climate-active gas and one of the most abundant biogenic volatile organic compounds (BVOC) released into the atmosphere. In the terrestrial environment, plants are the primary producers of isoprene, releasing between 500 and 750 million ...

Pyrite oxidization accelerates bacterial carbon sequestration in copper mine tailings [PDF]

Biogeosciences, 2019
Polymetallic mine tailings have great potential as carbon sequestration tools to stabilize atmospheric CO2 concentrations. However, previous studies focused on carbonate mineral precipitation, whereas the role of autotrophic bacteria in mine tailing ...
