ABSTRACT A phylogenomic approach was used to study the evolution of traits in the Cyanobacteria. A cyanobacterial backbone tree was constructed using multiple concatenated sequences from whole genome sequences. Additional taxa were added using a separate alignment that contained morphological...
ABSTRACT During deposition of late Archean–early Palaeoproterozoic Precambrian banded iron formations (BIFs) the downward flux of ferric hydroxide (Fe(OH)3) and phytoplankton biomass should have facilitated microbial Fe(III) reduction. However, quantifying the significance of such a metabolic...
ABSTRACT An approach for long‐term in vivo investigations on cyanobacterial cell surface changes at high spatial resolution by Atomic Force Microscopy (AFM) was developed in this study. Until recently, changes of bacterial cell surfaces due to changes of the chemical environment could neither be...
ABSTRACT Anaerobic methane‐oxidizing microbial communities in sediments at cold methane seeps are important factors in controlling methane emission to the ocean and atmosphere. Here, we investigated the distribution and carbon isotopic signature of specific biomarkers derived from anaerobic...
ABSTRACT Microbiological and geochemical surveys were conducted at three hot springs (Obsidian Pool, Sylvan Spring, and ‘Bison Pool’) in Yellowstone National Park (Wyoming, USA). Microbial community structure was investigated by polymerase chain reaction (PCR) amplification of 16S rRNA gene...
ABSTRACT In April 2004, the German Research Foundation (DFG) and the National Science Foundation (NSF) co‐organized a meeting for US and German junior geoscientists in Washington DC. As an outcome of this Research Conference titled ‘Earth, Fire, Water, Air and Life’, a follow‐up workshop took...
