Environmental microbiology research increasingly focuses on the single microbial cell as
the defining entity that drives environmental processes. The interactions of individual …

A detailed record of the early-Earth sulfur (S) cycle is chronicled by the S isotope values of
sulfide and sulfate preserved in the rock record. Interpretation of this record rests on our …

Quantitative information on the ecophysiology of individual microorganisms is generally
limited because it is difficult to assign specific metabolic activities to identified single cells …

We tested a previously described protocol for fluorescence in situ hybridization of marine
bacterioplankton with horseradish peroxidase-labeled rRNA-targeted oligonucleotide …

Carbonates of the 1640 million years (Ma) old Barney Creek Formation (BCF), McArthur
Basin, Australia, contain more than 22 different C40 carotenoid derivatives including …

The phylogenetic diversity of the bacterial and archaeal community in the water and
sediments of three large lakes of the Wadi An Natrun was investigated using 16S rRNA …

Using different techniques of molecular biology we investigated the bacterial diversity of the
chemocline of the meromictic Lake Cadagno. Cloning of a total community 16S rDNA PCR …

Low sulfate, euxinic water-column conditions were a common feature of many Precambrian
and Phanerozoic periods of ocean anoxia. The cycling of phosphorus in anoxic marine …

The nitrogen cycling of Lake Cadagno was investigated by using a combination of
biogeochemical and molecular ecological techniques. In the upper oxic freshwater zone …

The microstratification of the microbial community at the chemocline of Lake Cadagno and
the associated inorganic carbon fixation activity was studied by fine layer sampling. A deep …
