Carbon pools and isotopic trends in a hypersaline cyanobacterial mat

Autor: Jan-Hendrik Klock, Jürgen Möbius, Andrea Wieland, Walter Michaelis, Thomas Pape

Publikováno v: Geobiology. 6:171-186

The fine-scale depth distribution of major carbon pools and their stable carbon isotopic signatures (delta(13)C) were determined in a cyanobacterial mat (Salin-de-Giraud, Camargue, France) to study early diagenetic alterations and the carbon preserva

Extracellular polymeric substances (EPS) from cyanobacterial mats: characterisation and isolation method optimisation

Autor: Jan-Hendrik Klock, Walter Michaelis, Richard Seifert, Andrea Wieland

Publikováno v: Marine Biology. 152:1077-1085

Extracellular polymeric substances (EPS) play an important role in bacterial mat formation and sediment stabilisation of coastal zones. The analysis of these secretion products on a molecular level is a prerequisite to understand their formation mech

Regulation of photosynthesis and oxygen consumption in a hypersaline cyanobacterial mat (Camargue, France) by irradiance, temperature and salinity

Autor: Andrea Wieland, Michael Kühl

Publikováno v: FEMS Microbiology Ecology. 55:195-210

Short-term effects of irradiance (0-1560 micromol photons m(-2) s(-1)), temperature (10-25 degrees C), and salinity (40-160) on oxygenic photosynthesis and oxygen consumption in a hypersaline mat (Salin-de-Giraud, France) were investigated with micro

Distribution, identity and activity of symbiotic bacteria in anoxic aggregates from the hindgut of the sea urchinechinocardium cordatum

Autor: Helle Ploug, Marianne Seneca Thorsen, Caroline Kragelund, Per Halkjœr Nielsen, Andrea Wieland

Publikováno v: Ophelia. 57:1-12

Complex, anoxic aggregates of refractory organic matter and bacterial consortia are permanently present in the intestinal caecum of the spatangoid sea urchin Echinocardium cordatum. This study documents the presence of sulphate-reducing bacteria and

Irradiance and temperature regulation of oxygenic photosynthesis and O 2 consumption in a hypersaline cyanobacterial mat (Solar Lake, Egypt)

Autor: Michael Kühl, Andrea Wieland

Publikováno v: Marine Biology. 137:71-85

Short-term effects of temperature and irradiance on oxygenic photosynthesis and O2 consumption in a hypersaline cyanobacterial mat were investigated with O2 microsensors in a laboratory. The effect of temperature on O2 fluxes across the mat–water i

A novel, multi-layered methanotrophic microbial mat system growing on the sediment of the Black Sea

Publikováno v: Environmental microbiology. 10(8)

A novel microbially diverse type of 1- to 5-cm-thick mat performing anaerobic oxidation of methane (AOM) and covering several square metres of the seafloor was discovered in the Black Sea at 180 m water depth. Contrary to other AOM-mat systems of the

Changes in spatio-temporal distribution of bacterial and denitrifying communities were qualitatively studied in a microbial mat from Camargue (France). During a diel and a seasonal cycle, patterns of 16S rRNA and nitrite reductase genes (nirS and nir
