Microbial conversion of inorganic carbon to dimethyl sulfide in anoxic lake sediment (Plußsee, Germany) by Y. S. Lin, V. B. Heuer, T. G. Ferdelman, K.-U. Hinrichs

“…In anoxic environments, volatile methylated sulfides like methanethiol (MT) and dimethyl sulfide (DMS) link the pools of inorganic and organic carbon with the sulfur cycle. However, direct formation of methylated sulfides from reduction of dissolved inorganic carbon has previously not been demonstrated. …”

Diversity and Distribution of Sulfur Oxidation-Related Genes in Thioalkalivibrio, a Genus of Chemolithoautotrophic and Haloalkaliphilic Sulfur-Oxidizing Bacteria by Tom Berben, Lex Overmars, Dimitry Y. Sorokin, Dimitry Y. Sorokin, Gerard Muyzer

“…Despite this combination of extreme conditions, biodiversity in soda lakes is high, and the presence of diverse microbial communities provides a driving force for highly active biogeochemical cycles. The sulfur cycle is one of the most important of these and bacterial sulfur oxidation is dominated by members of the obligately chemolithoautotrophic genus Thioalkalivibrio. …”

Simultaneous Genome Sequencing of <i>Prosthecochloris ethylica</i> and <i>Desulfuromonas</i> <i>acetoxidans</i> within a Syntrophic Mixture Reveals Unique Pili and Protein Interact... by John A. Kyndt, Jozef J. Van Beeumen, Terry E. Meyer

“…The colorless component, on the other hand, contained a unique large multiheme cytochrome C and unique genes for e-pili (geopilin) formation, genetically clustered with a conserved ferredoxin gene, which are all expected to play an electron transfer role in the closed sulfur cycle in the syntrophic mixture. The findings from the simultaneous genome sequencing of the components of <i>Cp. ethylica</i> have implications for the phenomenon of direct interspecies interactions and coupled electron transfer in photosynthetic symbionts. …”
