The Opalinus Clay formation will host geological nuclear waste repositories in Switzerland. It is expected that gas pressure will build-up due to hydrogen production from steel corrosion, jeopardizing the integrity of the engineered barriers. In an in situ ...
Peptidoglycan is a fundamental structure for most bacteria. It contributes to the cell morphology and provides cell wall integrity against environmental insults. While several studies have reported a significant degree of variability in the chemical compos ...
Microbes have successfully colonized the deep subsurface, thanks to their small size and their diverse metabolic activities. This part of the biosphere remains a terra incognita for microbiologists, containing innumerable unknown microbial species and proc ...
Natural competence enables bacteria to take up exogenous DNA. The evolutionary function of natural competence remains controversial, as imported DNA can act as a source of substrates or can be integrated into the genome. Exogenous homologous DNA can also b ...
Mine tailings are a serious threat to the environment and public health. Remediation of these residues can be carried out effectively by the activation of specific microbial processes. This article presents detailed information about temporal changes in ba ...
Although a multitude of halogenated compounds are naturally produced, interest in biodegradation of these often toxic compounds has mainly been driven by anthropogenic contamination of soils and aquifers with huge amounts of chlorinated solvents (tetra- an ...
Natural attenuation of anaerobic aquifers contaminated with tetrachloroethene (PCE) often results in the accumulation of the intermediates cis-dichloroethene and vinyl chloride (VC) which are even more toxic than the parent compound. Reasons for this accum ...
Stable L-forms are cell wall-deficient bacteria which are able to multiply and propagate indefinitely, despite the absence of a rigid peptidoglycan cell wall. We investigated whether L-forms of the intracellular pathogen L. monocytogenes possibly retain pa ...
The term "micropollutants" includes xenobiotic compounds of various origins which can be found in aquatic environments at concentration levels of nano- to micrograms per liter and which present a negative effect on ecosystems. Many aromatic micropollutants ...
The Neoproterozoic sedimentary successions of the Sierras Bayas Group (SBG) are situated within the Tandilia Belt, Buenos Aires Province, Argentina. The Loma Negra Formation (LNF) from the upper part of the SBG has been investigated using a combination of ...
