Extensive processing of sediment pore water dissolved organic matter during anoxic incubation as observed by high-field mass spectrometry (FTICR-MS)
Juliana Valle,Michael Gonsior,Mourad Harir,Alex Enrich-Prast,Alex Enrich-Prast,Philippe Schmitt-Kopplin,David Bastviken,Ralf Conrad,Norbert Hertkorn +8 more
TL;DR: In this paper, the authors used ultra-high resolution mass spectrometry to trace differences in the composition of solid-phase extractable (PPL resin) pore water DOM (SPE-DOM) isolated from surface sediments of three boreal lakes before and after 40 days of anoxic incubation, with concomitant determination of CH4 and CO2 evolution.
Journal ArticleDOI
The behavior of antibiotic-resistance genes and their relationships with the bacterial community and heavy metals during sewage sludge composting.
TL;DR: The main contributors to antibiotic resistance genes (ARGs) profiles during the composting process under the addition of biochar (BC) and peat (PT) were not fully explored.
Journal ArticleDOI
Effects of heavy metals stress on chicken manures composting via the perspective of microbial community feedback
TL;DR: In this paper , the authors reveal the ecological adaptation and counter-effect of bacterial community under heavy metals stress during chicken manures composting, and evaluate environmental implications of HMS on composting.
Journal ArticleDOI
Antibiotic resistance genes attenuation in anaerobic microorganisms during iron uptake from zero valent iron: An iron-dependent form of homeostasis and roles as regulators.
TL;DR: In this paper, the authors investigated the influence of zero valent iron (ZVI) on ARGs dissemination in anaerobic bioreactor treating oxytetracycline (tet) containing wastewater, by deciphering the roles of iron homeostasis and regulatory effects.

Compositional and functional succession of bacterial and fungal communities is associated with changes in abiotic properties during pig manure composting
Xiaofang Wang,Jinxin Wan,Gaofei Jiang,Tianjie Yang,Samiran Banerjee,Zhong Wei,Xinlan Mei,Ville-Petri Friman,Yangchun Xu,Qirong Shen +9 more
TL;DR: In this article, the authors evaluated changes in abiotic compost properties and the succession of bacterial and fungal communities during pig manure composting for 90 days and found that the abundance fluctuations of most dominant bacteria and fungi taxa could be further associated with decreases in the concentrations of fulvic acid, cellulose, hemicellulose and overall biodegradation potential in the compost.

An improved Greengenes taxonomy with explicit ranks for ecological and evolutionary analyses of bacteria and archaea
Daniel McDonald,Morgan N. Price,Julia K. Goodrich,Julia K. Goodrich,Eric P. Nawrocki,Todd Z. DeSantis,Alexander J. Probst,Alexander J. Probst,Gary L. Andersen,Rob Knight,Rob Knight,Philip Hugenholtz +11 more
TL;DR: A ‘taxonomy to tree’ approach for transferring group names from an existing taxonomy to a tree topology is developed and used to apply the Greengenes, National Center for Biotechnology Information (NCBI) and cyanoDB (Cyanobacteria only) taxonomies to a de novo tree comprising 408 315 sequences.

Hyperthermophilic Composting Accelerates the Removal of Antibiotic Resistance Genes and Mobile Genetic Elements in Sewage Sludge
Hanpeng Liao,Xiaomei Lu,Christopher Rensing,Ville-Petri Friman,Stefan Geisen,Zhi Chen,Zhen Yu,Zhong Wei,Shungui Zhou,Yong-Guan Zhu +9 more
TL;DR: It is suggested that hyperthermophilic composting can significantly enhance the removal of ARGs and MGEs and that the mechanisms of ARG and M GE removal can depend on composting temperature.

Succession of the functional microbial communities and the metabolic functions in maize straw composting process.
TL;DR: Results showed that humic acid contents in loosely combined humus (HA1) and stably combined humUS (HA2) increased after composting and Staphylococcus, Cellulosimicrobium and Ochrobactrum possibly participated in the transformation of the process.

Improved lignocellulose-degrading performance during straw composting from diverse sources with actinomycetes inoculation by regulating the key enzyme activities.
TL;DR: The combined application of actinomycetes inoculation and urea addition as a source of nitrogen was suggested to regulate the key enzyme activities and lignocellulose degradation, which lays a foundation for effectively managing organic wastes from different types of crop straws by composting.

Molecular Insights into the Transformation of Dissolved Organic Matter in Landfill Leachate Concentrate during Biodegradation and Coagulation Processes Using ESI FT-ICR MS.
Ziwen Yuan,Chen He,Quan Shi,Chunming Xu,Zhenshan Li,Zhenshan Li,Chengzhai Wang,Chengzhai Wang,Hua-Zhang Zhao,Hua-Zhang Zhao,Jinren Ni,Jinren Ni +11 more
TL;DR: Molecular compositions of dissolved organic matter (DOM) in leachate concentrate, as well as changes after anaerobic/aerobic biodegradation and coagulation with salts, were characterized using electrospray ionization (ESI) coupled with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS).
