Sulfur oxidation and reduction are coupled to nitrogen fixation in the roots of the salt marsh foundation plant Spartina alterniflora

Nature Communications
Heterotrophic activity, primarily driven by sulfate-reducing prokaryotes, has traditionally been linked to nitrogen fixation in the root zone of coastal marine plants, leaving the role of chemolithoautotrophy in this process unexplored.

Thiocapsa, Lutimaribacter, and Delftia Are Major Bacterial Taxa Facilitating the Coupling of Sulfur Oxidation and Nutrient Recycling in the Sulfide-Rich Isinuka Spring in South Africa

Biology
Sulfur cycling is a fundamental biogeochemical process, yet its microbial underpinnings in environments like the Isinuka sulfur pool remain poorly understood.

Physiology of purple sulfur bacteria forming macroscopic aggregates in Great Sippewissett Salt Marsh, Massachusetts [PDF]

, 1993
Purple bacterial aggregates found in tidal pools of Great Sippewissett Salt Marsh (Falmouth, Cape Cod, MA) were investigated in order to elucidate the ecological significance of cell aggregation. Purple sulfur bacteria were the dominant microorganisms in

Transcriptomic and proteomic analyses of Desulfovibrio vulgaris biofilms: carbon and energy flow contribute to the distinct biofilm growth state. [PDF]

, 2012
BackgroundDesulfovibrio vulgaris Hildenborough is a sulfate-reducing bacterium (SRB) that is intensively studied in the context of metal corrosion and heavy-metal bioremediation, and SRB populations are commonly observed in pipe and subsurface ...

Metatranscriptomic analysis of sulfur oxidation genes in the endosymbiont of Solemya velum

Frontiers in Microbiology, 2011
Thioautotrophic endosymbionts in the Domain Bacteria mediate key sulfur transformations in marine reducing environments. However, the molecular pathways underlying symbiont metabolism and the extent to which these pathways are expressed in situ are ...

The Fermenting Bacterium Malonomonas rubra is Phylogenetically Related to Sulfur-Reducing Bacteria and Contains a c-Type Cytochrome similar to those of Sulfur and Sulfate Reducers [PDF]

Systematic and Applied Microbiology, 1998
Malonomonas rubra is a microaerotolerant fermenting bacterium which can maintain its energy metabolism for growth by decarboxylation of malonate to acetate. 16S rRNA sequence analysis revealed that M. rubra is closely related to the cluster of mesophilic sulfur-reducing bacteria within the delta subclass of the Proteobacteria, with the fermenting ...

Thermophilic Sulfate Reduction in Hydrothermal Sediment of Lake Tanganyika, East Africa [PDF]

, 1994
In environments with temperatures above 60 degrees C, thermophilic prokaryotes are the only metabolically active life-forms. By using the (SO42-)-S-35 tracer technique, we studied the activity of sulfate-reducing microorganisms (SRM) in hot sediment from

Close interspecies interactions between prokaryotes from sulfureous environments

Frontiers in Microbiology, 2011
Green sulfur bacteria are obligate photolithoautotrophs that require highly reducing conditions for growth and can utilize only a very limited number of carbon substrates. These bacteria thus inhabit a very narrow ecologic niche.

Possible roles of manganese redox chemistry in the sulfur cycle [PDF]

Sulfate reducing bacteria (SRB) are very potent MnO2 reducers by virtue of their sulfide production: H2S reacts rapidly with MnO2 to yield Mn(2), elemental sulfur, and water.

Characterization of chemosynthetic microbial mats associated with intertidal hydrothermal sulfur vents in White Point, San Pedro, CA, USA

Frontiers in Microbiology, 2016
The shallow-sea hydrothermal vents at White Point (WP) in Palos Verdes (PV) on the southern California coast support microbial mats and provide easily accessed settings in which to study chemolithoautotrophic sulfur cycling.
