TL;DR: In this article, the authors provide microscopic evidence for a structured consortium of archaea and sulphate-reducing bacteria, which are identified by fluorescence in situ hybridization using specific 16S rRNA-targeted oligonucleotide probes.

TL;DR: In this paper, a comparative survey of aerobic and anaerobic mineralization in the sea bed based on direct rate measurements of the two processes is presented, and the results demonstrate a surprisingly high contribution from the sulphate-reducers.

TL;DR: Evidence for bacteria that anaerobically oxidize ammonium with nitrite to N2 in the world's largest anoxic basin, the Black Sea is provided and anammox bacteria have been identified and directly linked to the removal of fixed inorganic nitrogen in the environment.

TL;DR: There is still a long way to go in understanding of the microbial microenvironments and of the nature of the microorganisms that carry out the measured metabolic activities, and most chemical and radiotracer techniques in use today operate on a centimeter or at best on a millimeter scale and in most cases their results cannot be directly related to the relevant microorganisms.

TL;DR: In this paper, the cyclic transformations of inorganic sulfur compounds in the sediments of a Danish fjord were followed for two years and the in situ rate of sulfate reduction measured with a radiotracer technique together with chemical determinations of various sulfur compounds were used to calculate a budget of the complete sulfur cycle.
