The special issue summarises and highlights key findings of the research unit DASIM funded by the German Research Foundation (DFG) on the process of denitrification. Progress was made in several areas including the development of new and advanced methods to quantify N 2 fluxes such as a new 15 N gas flux method, enhanced Raman spectroscopy and a new incubation system to study plant-soil interactions in He-O 2 atmosphere. Under...

Volumetric absorptive microsampling (VAMS) techniques have gained popularity these last years as innovative tool for collection of blood pharmacokinetic (PK) samples in clinical trials as they offer many advantages over dried blood spot and conventional venous blood sampling. The use of Mitra ® , a blood collection device based on volumetric absorptive microsampling (VAMS) technology, was implemented during clinical developmen...

Summary The rulAB operon of P seudomonas spp. confers fitness traits on the host and has been suggested to be a hotspot for insertion of mobile elements that carry avirulence genes. Here, for the first time, we show that rulB on plasmid pWW 0 is a hotspot for the active site‐specific integration of related integron‐like elements ( ILE s) found in six environmental pseudomonads (strains FH 1– FH 6). Integration into rulB on pWW...
