Sulfonamide antibiotics have a wide application range in human and veterinary medicine. Because they tend to persist the environment, pose potential problems with regard propagation of antibiotic resistance. Here, we identified metabolites formed during degradation sulfamethoxazole other sulfonamides Microbacterium sp. strain BR1. Our experiments showed that proceeded along an unusual pathway initiated by ipso-hydroxylation subsequent fragmentation parent compound. The NADH-dependent...
In constructed wetlands, organic pollutants are mainly degraded via microbial processes. Helophytes, plants that commonly used in these systems, provide oxygen and root exudates to the rhizosphere, stimulating degradation. While treatment performance of wetlands can be remarkable, a mechanistic understanding degradation processes rhizosphere is still limited. We investigated toluene removal wetland model system combining 16S rRNA gene sequencing, metaproteomics (13) C-toluene situ...
ABSTRACT In the present study, microbial toluene degradation in controlled constructed wetland model systems, planted fixed-bed reactors (PFRs), was queried with DNA-based methods combination stable isotope fractionation analysis and characterization of toluene-degrading isolates. Two PFR replicates were operated as sole external carbon electron source for 2 years. The bulk redox conditions these systems hypoxic to anoxic. autochthonous bacterial communities, analyzed by Illumina sequencing...
Multidimensional compound-specific stable isotope analysis (CSIA) was applied in combination with RNA-based molecular tools to characterize methyl tertiary (tert-) butyl ether (MTBE) degradation mechanisms occurring biofilms an aerated treatment pond used for remediation of MTBE-contaminated groundwater. The main pathway MTBE oxidation elucidated by linking the low-level fractionation (mean carbon isotopic enrichment factor [ε(C)] -0.37‰ ± 0.05‰ and no significant hydrogen [ε(H)]) observed...
ABSTRACT Pseudomonas putida mt-2 harbors the TOL plasmid (pWWO), which contains genes encoding enzymes necessary to degrade toluene aerobically. The xyl are clustered in upper operon and encode of pathway that benzoate, while lower ( meta -cleavage pathway) for conversion benzoate tricarboxylic acid cycle intermediates, encoded a separate operon. In this study, effects oxygen availability oscillation on expression catabolic involved degradation were studied by using P. as model bacterium....
Previously, Planted Fixed-Bed Reactors (PFRs) have been used to investigate microbial toluene removal in the rhizosphere of constructed wetlands. Aerobic degradation was predominant these model systems although bulk redox conditions were hypoxic anoxic. However, culture-independent approaches indicated also that microbes capable anaerobic abundant. Therefore, we aimed at isolating anaerobic-toluene degraders from one PFRs. From obtained colonies which consisted spirilli-shaped bacteria, a...
Dimethylphenols (DMP) are toxic compounds with high environmental mobility in water and one of the main constituents effluents from petro- carbochemical industry. Over last few decades, use constructed wetlands (CW) has been extended domestic to industrial wastewater treatments, including petro-carbochemical effluents. In these systems, role during transformation mineralization organic pollutants is played by microorganisms. Therefore, understanding bacterial degradation processes isolated...
Self-transferable plasmids of the incompatibility group P-1 (IncP-1) are considered important carriers genes for antibiotic resistance and other adaptive functions. In laboratory, these have a broad host range; however, little is known about their in situ profile. this study, we discovered that Thauera aromatica K172T , facultative denitrifying microorganism capable degrading various aromatic compounds, contains plasmid highly similar to IncP-1 ε archetype pKJK5. The harbours multiple...
Due to the COVID-19 pandemic, Delft University of Technology in Netherlands (TU Delft) stopped its activities on campus until autumn 2021 and moved all teaching an online setting. This article describes challenges lessons learned from successfully moving basic programming workshops, Software Carpentry online. The details local TU context, workshop tools that were employed, roles organising team played organise run these workshops. To adapt it was important adjust original planning programme...

Modern research institutions are faced with rapidly increasing challenges imposed by data-driven science and have to deal new demands from funding agencies publishers regarding open access data as well the Code of Conduct for Research Integrity on reproducibility results. In reply these requirements, Technical University Denmark (DTU) has adapted a two-fold strategy bringing together decision-makers, relevant support units in administration researchers all departments task designing policies...
