Bismuth(III) sulfide is a chemical compound of bismuth and sulfur. It occurs in nature as the mineral bismuthinite. Synthesis . Bismuth(III) sulphide can be prepared by reacting a bismuth(III) salt with hydrogen sulfide:
Bismuth Sulphite Agar is a modification of original Wilson and Blair Medium (5-7). It is also recommended by various It is also recommended by various Associations (8-13) for the isolation and preliminary identification of Salmonella Typhi and other Salmonellae from
Bismuth(III) sulfide is isostructural with SbS, stibnite. Bismuth atoms are in two different environments, both of which have 7 coordinate Bismuth atoms, 4 in a near planar rectangle and three more distant making an irregular 7-coordination group.
Bismuth Sulfite Agar is a selective medium used to isolate Salmonella Typhi and other salmonellas in pathological products of animal origin, water, dairy and other food products. HISTORY In 1926, Wilson and Blair combined bismuth and sodium sulfite in a medium destined to isolate Salmonella of the typhi and paratyphi groups. In 1956, Hajna and Damon described a modified formula which was ...
BISMUTH SULFITE AGAR - For in vitro use only - Catalogue No. PB68 Our Bismuth Sulfite Agar is a selective and differential medium used for the isolation of Salmonella species from a variety of samples including foods and clinical specimens. Wilson and Blair published the initial formulation in 1926. Numerous researchers including Cope and Kasper, Gunther and Tuft, as well as Hajna and Perry ...
Bismuth(III) sulfide is a chemical compound of bismuth and sulfur. It occurs in nature as the mineral bismuthinite. Synthesis. Bismuth(III) sulfide can be prepared by reacting a bismuth(III) salt with hydrogen sulfide:
CM0201, Bismuth Sulphite Agar (Modified Wilson & Blair Medium). a medium for the isolation of Salmonella typhi and other salmonellae. Particularly useful for the isolation of lactose-fermenting salmonellae. Please note maximum shelf life of 12 months.
Bismuth(III) sulfide is used as a starting material to produce other bismuth compounds. It is used in glass industry as a colorant, electronic ceramics, scintillator BGO and in superconductors. It is used in glass industry as a colorant, electronic ceramics, scintillator BGO and in superconductors.
Bismuth sulfite agar is a modification of the original Wilson and Blair selective diagnostic medium used for the isolation of Salmonella typhi and other salmonellae from food and other materials, sewage and water. Bismuth sulfite and brilliant green are the selective agents. The medium also contains indicators for sulfide production. The use of this medium is advocated by several authorities ...
This is a large segment of the sulfide class whose difference from the other sulfides lies in the position of the semi-metal ions. In most ordinary sulfides that contain a semi-metal such as antimony, arsenic or bismuth, they substitute in the sulfur positions, but in sulfosalts they substitute for the metal ions and bond with the sulfurs. The term sulfosalts came from a theory that these ...
PEGylated chitosan nanoparticles with embedded bismuth sulfide for dual-wavelength fluorescent imaging and photothermal therapy. Sodium sulfite pH-buffering effect for improved xylose-phenylalanine conversion to N-(1-deoxy-d-xylulos-1-yl)-phenylalanine during an aqueous Maillard reaction.
Bismuth(III) sulfide Facts for Kids - Kiddle encyclopedia. Bismuth(III) sulfide, also known as bismuth sulfide, is a chemical compound.Its chemical formula is Bi 2 S 3.It has bismuth and sulfide ions in it.
Bismuth: Bismuth has also been shown to reduce hydrogen sulfide gas in a few studies. It is typical for people with an excess amount of hydrogen sulfide gas to have their stools turn black when they take bismuth. This can also be used as a simple diagnostic tool to determine whether H
Bismuth Sulfite Agar is selective due to the presence of inhibitors, and is differential on the basis of hydrogen sulfide production. (13) Beef extract and peptones provide nitrogen, vitamins and minerals. Dextrose is an energy source. Bismuth sulfite and brilliant green are selective agents, inhibiting most commensal gram-positive and gram-negative organisms other than Salmonella species and ...
Bismuth Sulfite Agar was introduced by Wilson and Blair in 1927 for selective isolation of typhoid and paratyphoid groups of bacteria from stool specimens. 1 The formulation was modified by Hajna in 1951, and by Hajna and Damon in 1956, by substituting bismuth ammonium citrate
Four of the bismuth and all of the lithium ions present in the crystal structure are octahedrally coordinated by six sulfide ions. The remaining Bi3 is coordinated by five close sulfide ions in the fashion of a square pyramid. This position is not accidentally unoccupied by lithium, as a square pyramidal coordination would be unfavorable. The crystal structure of LiBi
Bismuth Sulfite Agar is a selective culture medium used for the isolation of Salmonella typhi and other enteric bacilli. HISTORY/SUMMARY: Bismuth Sulfite Agar was first described by Wilson and Blair as a combination of bismuth and medium sulfite for selection of typhoid and paratyphoid groups of bacteria from stool specimens.
