unusual facts about Sulfate-reducing bacteria


Gypsum recycling

Sulfate-reducing bacteria convert sulfates to toxic hydrogen sulphide gas; they are killed by exposure to air, but the moist, airless, carbon-containing environment in a landfill is a good habitat for them.


Arsenate-reducing bacteria

It appears that arsenate reduction by the Desulfovibrio strain Ben-RA is catalyzed by an arsenate reductase that is encoded by a chromosomally-borne gene shown to be homologous to the arsC gene of the Escherichia coli plasmid, R773 ars system.

Barium sulfate suspension

The patient is instructed to take nothing by mouth, which means to abstain from eating and drinking (fasting), with the exception of drinking the barium sulfate suspension.

Burkholderia heleia

Burkholderia heleia is a gram-negative, nitrogen-fixing, aerobic, non-spore-forming, rod-shaped bacterium from the genus of Burkholderia and the family of Burkholderiaceae which was isolated from the Chinese water chestnut Eleocharis dulcis in acid sulfate soil areas of Vietnam.

Chondroitin sulfate proteoglycan

CSPG4 (melanoma-associated chondroitin sulfate proteoglycan, NG2)

Cloud condensation nuclei

The particles may be composed of dust or clay, soot or black carbon from grassland or forest fires, sea salt from ocean wave spray, soot from factory smokestacks or internal combustion engines, sulfate from volcanic activity, phytoplankton or the oxidation of sulfur dioxide and secondary organic matter formed by the oxidation of VOCs.

Dehydroepiandrosterone sulfate

Dehydroepiandrosterone sulfate is produced by the addition of a sulfate group, catalyzed by the sulfotransferase enzymes SULT1A1 and SULT1E1, which also produce estrone sulfate from estrone.

HS3ST3B1

The Sulfotransferase domain of this enzyme is highly similar to the same domain of heparan sulfate D-glucosaminyl 3-O-sulfotransferase 3A1 and these two enzymes sulfate an identical disaccharide.

It is a type II integral membrane protein and possesses heparan sulfate glucosaminyl 3-O-sulfotransferase activity ( HS3ST3A1).

Kieserite

In early 2005, Mars Express, a European Space Agency orbiter, discovered evidence of kieserite in patches of Valles Marineris (the largest canyon on Mars), along with gypsum and polyhydrated sulfates.

Magnesium sulfate

Magnesium sulfate has been used as an experimental treatment of Irukandji syndrome caused by envenomation by certain species of Irukandji jellyfish, however the efficacy of this treatment remains unproven.

Metachromasy

The modern understanding why metachromasy occurs was advanced by Belgian histologist Lucien Lison, who studied it between 1933 and 1936 and ascertained its value in the quantitative determination of sulfate esters of high molecular weight.

Microbicides for sexually transmitted diseases

On February 1, 2007, the International AIDS Society announced that two phase III trials of cellulose sulfate had been stopped because preliminary results suggested a potential increased risk of HIV in women who used the compound.

Mina, Nevada

Thenardite, a sodium sulfate mineral, Na2SO4, found at Sodaville

Potassium sulfate

Potassium sulfate (K2SO4) has been known since early in the 14th century, and it was studied by Glauber, Boyle and Tachenius.

Seven Lakes of San Pablo

In a recent rocks and sediment analysis or petrographic study on the lakes and adjoining rivers in San Pablo, sulfate concentrations were considerably higher than the naturally occurring sulfates from volcanism.

SO4

Sulfate, SO42-, in organic chemistry, a salt of sulfuric acid

Sulfate

Iron sulfate, a common form of iron in mineral supplements for humans, animals, and soil for plants

Sulfonucleotide reductase

(Inorganic sulfate occurs abundantly on Earth; terrestrial organisms must use sulfate assimilation to convert it to sulfide.)

Two-dimensional gel electrophoresis

To obtain a separation by size and not by net charge, as in IEF, an additional charge is transferred to the proteins by the use of Coomassie Brilliant Blue or lithium dodecyl sulfate.
