Sulfide- and nitrite-dependent nitric oxide production in the intestinal tract [PDF]
, 2011 In the gut ecosystem, nitric oxide (NO) has been described to have damaging effects on the energy metabolism of colonocytes. Described mechanisms of NO production are microbial reduction of nitrate via nitrite to NO and conversion of l-arginine by NO ...

Seasonal changes in microbial dissolved organic sulfur transformations in coastal waters [PDF]
, 2020 The marine trace gas dimethylsulfide (DMS) is the single most important biogenic source of atmospheric sulfur, accounting for up to 80% of global biogenic sulfur emissions.

An Investigation into the Suitability of Sulfate-Reducing Bacteria as Models for Martian Forward Contamination [PDF]
, 2018 The NASA Planetary Protection policy requires interplanetary space missions do not compromise the target body for a current or future scientific investigation and do not pose an unacceptable risk to Earth, including biologic materials.

Anaerobic degradation of dimethylsulfoniopropionate to 3-S-methylmercaptopropionate by a marine Desulfobacterium strain [PDF]
, 1993 Dimethylsulfoniopropionate, an osmolyte of marine algae, is thought to be the major precursor of dimethyl sulfide, which plays a dominant role in biogenic sulfur emission.

Sulfur-Element containing metabolic pathways in human health and crosstalk with the microbiome
Biochemistry and Biophysics Reports, 2023 In humans, methionine derived from dietary proteins is necessary for cellular homeostasis and regeneration of sulfur containing pathways, which produce inorganic sulfur species (ISS) along with essential organic sulfur compounds (OSC).

Indian Journal of Forensic Medicine & Toxicology, 2021 The current study has developed a proprietary system and a special device for the supply of oxygen-freenitrogen gas with a mixture of carbon dioxide and 80:20% according to the laboratory conditions required forthe growth of sulfur-reducing bacteria. To find the best medium that fits the bacteria in those environmentswith shortening incubation period ...

The identification and biogeochemical interpretation of fossil magnetotactic bacteria [PDF]
, 2008 Magnetotactic bacteria, which most commonly live within the oxic-anoxic transition zone (OATZ) of aquatic environments, produce intracellular crystals of magnetic minerals, specifically magnetite or greigite.
