Bioelectrochemically enhanced degradation of bisphenol S: mechanistic insights from stable isotope-assisted investigations

iScience, 2021
Summary: Electroactive microbes is the driving force for the bioelectrochemical degradation of organic pollutants, but the underlying microbial interactions between electrogenesis and pollutant degradation have not been clearly identified.

Multisubstrate DNA stable isotope probing reveals guild structure of bacteria that mediate soil carbon cycling. [PDF]

Proc Natl Acad Sci U S A, 2021
Significance Soil organic matter contains a large fraction of global C whose fate is largely governed by soil microbial communities. Global C-cycle models can be improved using information about microbial processes in soil, but the inner workings of soil communities remain largely hidden from view.

¹⁵N-DNA stable isotope probing reveals niche differentiation of ammonia oxidizers in paddy soils. [PDF]

Appl Microbiol Biotechnol
Abstract Chemoautotrophic canonical ammonia oxidizers (ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB)) and complete ammonia oxidizers (comammox Nitrospira) are accountable for ammonia oxidation, which is a fundamental process of nitrification in terrestrial ecosystems.

Cultivation-independent detection of autotrophic hydrogen-oxidizing bacteria by DNA stable-isotope probing. [PDF]

Appl Environ Microbiol, 2011
ABSTRACTKnallgas bacteria are a physiologically defined group that is primarily studied using cultivation-dependent techniques. Given that current cultivation techniques fail to grow most bacteria, cultivation-independent techniques that selectively detect and identify knallgas bacteria will improve our ability to study their diversity and distribution.

Sulfonamide-metabolizing microorganisms and mechanisms in antibiotic-contaminated wetland sediments revealed by stable isotope probing and metagenomics

Environment International, 2022
Sulfonamide (SA) antibiotics are ubiquitous pollutants in livestock breeding and aquaculture wastewaters, which increases the propagation of antibiotic resistance genes.

Elevated and atmospheric‐level methane consumption by soil methanotrophs of three grasslands in China

Grassland Research, 2023
Background Methane (CH4) oxidation driven by soil aerobic methanotrophs demonstrates the capacity of grassland as a CH4 sink. Methods In this study, we compared the oxidation characteristics of atmospheric‐level and elevated concentration (10%) CH4 in a ...

Organic Matter Type Defines the Composition of Active Microbial Communities Originating From Anoxic Baltic Sea Sediments

Frontiers in Microbiology, 2021
Carbon cycling in anoxic marine sediments is dependent on uncultured microbial communities. Niches of heterotrophic microorganisms are defined by organic matter (OM) type and the different phases in OM degradation.

Autotoxin affects the rhizosphere microbial community structure by influencing the secretory characteristics of grapevine roots

Frontiers in Microbiology, 2022
Autotoxins secreted by roots into the soil can trigger rhizosphere microecological imbalances and affect root secretory properties resulting in conditions such as replanting disease.

Functional characterization of an anaerobic benzene‐degrading enrichment culture by DNA stable isotope probing [PDF]

Environmental Microbiology, 2010
Summary The flow of carbon under sulfate‐reducing conditions within a benzene‐mineralizing enrichment culture was analysed using fully labelled [ 13 C 6 ]‐benzene. Over 180 days of incubation, 95% of added 13
