Rhodanese activity: a simple and reliable taxonomic tool for gram-negative bacteria. 1982

B Lányi

The thiosulphate: cyanide sulphurtransferase (rhodanese) test of Vandenbergh, Bawdon and Berk (1979) has been simplified and 2469 strains from a wide variety of sources representing different biochemical, serological or phage-pattern entities were tested. The percentages of rhondanese-producing strains were: Escherichia coli 98%, Shigella flexneri serovars 1-5%, X and Y 0%, other shigellae 73-100%, Yersinia spp. 0%, Salmonella subgenera I-IV 0%, Citrobacter freundi 16%, Klebsiella 37%, Enterobacter 4%, Hafnia alvei 61%, Proteus spp. 0%, Pseudomonas spp. 98-100%. Rhondanese production by S. flexneri serovar 6 supports the view that this group of bacteria should be removed from S. flexneri and placed in another species of Shigella.

UI MeSH Term Description Entries
D011549 Pseudomonas A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants. Chryseomonas,Pseudomona,Flavimonas
D004755 Enterobacteriaceae A family of gram-negative, facultatively anaerobic, rod-shaped bacteria that do not form endospores. Its organisms are distributed worldwide with some being saprophytes and others being plant and animal parasites. Many species are of considerable economic importance due to their pathogenic effects on agriculture and livestock. Coliform Bacilli,Enterobacteria,Ewingella,Leclercia,Paracolobactrum,Sodalis
D001419 Bacteria One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive. Eubacteria
D013466 Sulfurtransferases Enzymes which transfer sulfur atoms to various acceptor molecules. EC 2.8.1. Sulfurtransferase
D013884 Thiosulfate Sulfurtransferase An enzyme that catalyzes the transfer of the planetary sulfur atom of thiosulfate ion to cyanide ion to form thiocyanate ion. EC 2.8.1.1. Rhodanese,Thiosulfate Cyanide Transsulphurase,Thiosulfate Sulphurtransferase,Cyanide Transsulphurase, Thiosulfate,Sulfurtransferase, Thiosulfate,Sulphurtransferase, Thiosulfate,Transsulphurase, Thiosulfate Cyanide
