Unveiling Marine Plastic Degraders Through DNA-Stable Isotope Probing
Journal of Hazardous MaterialsPlastic biodegradation in natural environments is performed by the microbial biofilm living on its surface. This study identifies for the first time plastic degraders in marine environment, by using stable isotope tracers. Polyhydroxybutyrate (PHB) biodegradation was proved by monitoring microbial cell growth (via scanning electron microscopy and flow ...

Environmental Pollution, 2021
The accumulation of estrogens in aquatic environments has drawn increasing public concern due to their adverse effects on aquatic ecosystems and human health. Bacteria play important roles in eliminating estrogens from the environment, but knowledge of the identity and functions of the microorganisms involved in metabolizing these steroid hormones in ...

Autotrophic denitrification has attracted increasing attention for wastewater with insufficient organic carbon sources. Nevertheless, in situ identification of autotrophic denitrifying communities in reactors remains challenging. Here, a process combining micro-electrolysis and autotrophic denitrification with high nitrate removal efficiency was ...

15N2–DNA–stable isotope probing of diazotrophic methanotrophs in soil
Soil Biology and Biochemistry, 2008Abstract Nucleic acid stable isotope probing (SIP) is a powerful tool that can identify and characterize the microorganisms that mediate specific soil processes and explore the flow of C and N through functional groups in the soil food web. While 13 C–SIP has been used successfully in a range of applications, methodological constraints have limited ...

DNA stable Isotope Probing and Gene Mining
2014This chapter reviews the state of the art in isolation of new and valuable industrial enzymes from natural biodiversity, and discusses the strengths and weaknesses of each approach and shows how results with DNA stable isotope probing (DNA-SIP) indicate that this technique has substantial promise for improving the effectiveness of strategies for ...

Biodegradation, 2011
Cultivation-independent analyses were applied to study the structural diversity of the bacterial community which developed in groundwater inoculated microcosms actively metabolizing monochlorobenzene (MCB) under anaerobic conditions. Addition of (13)C-labelled MCB demonstrated that the community produced (13)CO(2) as a metabolite at slightly increasing

DNA Stable Isotope Probing to Examine Organisms Involved in Biodegradation
2019In situ applications of molecular biology to terrestrial and aquatic ecosystems have advanced the study of activities of microorganisms without the need for cultivation. DNA-based fingerprinting tools, such as 16S-TTGE, T-RFLP, DGGE, or pyrosequencing, facilitate in assessing pesticide impacts on microbial community composition.

Benzo[a]pyrene (BaP) is a typical high-molecular-weight PAH with carcinogenicity. Rhizoremediation is commonly applied to remove soil BaP, but its mechanism remains unclear. The role of inducers in root exudates in BaP rhizoremediation is rarely studied.
