TL;DR: Evidence for a fourth pathway to produce oxygen is presented, possibly of considerable geochemical and evolutionary importance, and opens up the possibility that oxygen was available to microbial metabolism before the evolution of oxygenic photosynthesis.
Journal ArticleDOI
Oxygenic photosynthesis as a protection mechanism for cyanobacteria against iron-encrustation in environments with high Fe2+ concentrations
Danny Ionescu,Danny Ionescu,Bettina Buchmann,Christine Heim,Stefan Häusler,Dirk de Beer,Lubos Polerecky,Lubos Polerecky +7 more
TL;DR: It is proposed that, due to limited mass transfer, high photosynthetic activity in Fe2-rich environments forms a protective zone where Fe2+ precipitates abiotically at a non-lethal distance from the cyanobacteria.
Journal ArticleDOI
Effects of biofilm structures on oxygen distribution and mass transport.
TL;DR: Aerobic biofilms were found to have a complex structure consisting of microbial cell clusters (discrete aggregates of densely packed cells) and interstitial voids, implying that to accurately describe biofilm activity, the relation between the arrangement of structural components and mass transfer must be undrstood.
Journal ArticleDOI
Novel microbial communities of the Haakon Mosby mud volcano and their role as a methane sink
Helge Niemann,Helge Niemann,Tina Lösekann,Dirk de Beer,Marcus Elvert,Marcus Elvert,Thierry Nadalig,Thierry Nadalig,Katrin Knittel,Rudolf Amann,Eberhard-Jürgen Sauter,Michael Schlüter,Michael Klages,Jean Paul Foucher,Antje Boetius,Antje Boetius,Antje Boetius +16 more
TL;DR: It is found that the upward flow of sulphate- and oxygen-free mud volcano fluids restricts the availability of these electron acceptors for methane oxidation, and hence the habitat range of methanotrophs, which limits the capacity of the microbial methane filter at active marine mud volcanoes to <40% of the total flux.
Journal ArticleDOI
Direct measurement of chlorine penetration into biofilms during disinfection.
TL;DR: The data indicate that the limited penetration of chlorine into the biofilm matrix is likely to be an important factor influencing the reduced efficacy of this biocide against biofilms as compared with its action against planktonic cells.
