Pelodictyon phaeoclathratifovme sp. nov., a new brown-colored member of the Chlorobiaceae forming net-like colonies [PDF]

open access: yes, 1989
A new strain of the green sulfur bacteria was isolated from the monimolimnion of Buchensee (near Radolfzell, Lake Constance region, FRG). Single cells were rod-shaped, nonmotile and contained gas vacuoles. Typical net-like colonies were formed by ternary

cis,trans,cis-1,2,3,4-Tetrakis[2-(ethylsulfanyl)phenyl]cyclobutane

open access: yesIUCrData, 2016
The title cyclobutane derivative, C36H40S4, formed serendipitously through a photochemically initiated [2 + 2] cycloaddition. The asymmetric unit contains half a molecule with the 2-(ethylsulfanyl)phenyl substituents in a cis configuration, the other ...

Lunar ore geology and feasibility of ore mineral detection using a far-IR spectrometer

open access: yesFrontiers in Earth Science, 2023
Lunar sulfides and oxides are a significant source of noble and base metals and will be vital for future human colonies’ self-sustainability. Sulfide detection (pyrite and troilite) applies to many technological fields and use cases, for example, as a ...

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]

open access: yes, 2010
Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.

Gut microbiota facilitates dietary heme-induced epithelial hyperproliferation by opening the mucus barrier in colon [PDF]

open access: yes, 2015
Colorectal cancer risk is associated with diets high in red meat. Heme, the pigment of red meat, induces cytotoxicity of colonic contents and elicits epithelial damage and compensatory hyperproliferation, leading to hyperplasia.

Optimization of factors affecting on sulfide oxidation from synthetic spent caustic by Haloalkaliphilic Thioalkalivibrio versutus by focus on sodium ion effect: Application of response surface methodology [PDF]

open access: yesIranian Journal of Chemical Engineering, 2017
In the present study, the effects of four factors including initial sulfide concentration (mg l-1 ), agitation speed (rpm), amount of inoculums (%) and sodium concentration (mg l-1) on removal efficiency (%R) and yield of sulfate production by ...

Sulfur Cave (Romania), an extreme environment with microbial mats in a CO2-H2S/O2 gas chemocline dominated by mycobacteria

open access: yesInternational Journal of Speleology, 2018
Sulfur Cave (Puturosu Mountain, Romania) is an extreme environment, unique for displaying life in a gas chemocline. The lower part of the cave is filled with CO2, CH4, and H2S of mofettic origin, while the upper part contains air that floats above the ...
