DOI: 10.1002/mbo3.1014
Abstract: The marine sulfur cycle is substantially fueled by the phytoplankton osmolyte dimethylsulfoniopropionate (DMSP). This metabolite can be metabolized by bacteria, which results in the emission of the volatile sulfur species methanethiol (MeSH) and the climate‐cooling… read more here.

DOI: 10.1007/s11430-017-9234-x
Abstract: Sulfur cycling in the biosphere is tightly interwoven with the cycling of carbon and nitrogen, through various biological and geochemical processes. Marine microorganisms, due to their high abundance, diverse metabolic activities, and tremendous adaptation potential,… read more here.

DOI: 10.1021/acs.est.0c08191
Abstract: Although denitrification-dependent chemolithotrophic sulfur oxidizers proliferated in tsunami-deposited marine sediment with nitrate amendment, their ecophysiological roles in biogeochemical carbon transfer are not addressed. We employed time-resolved high-sensitivity 13C-bicarbonate probing of rRNA to unveil the carbon… read more here.

DOI: 10.3390/life12040523
Abstract: Water present on the surface of early Mars (>3.0 Ga) may have been habitable. Characterising analogue environments and investigating the aspects of their microbiome best suited for growth under simulated martian chemical conditions is key… read more here.
