Hydrolysis of lithocholate sulfate by Pseudomonas aeruginosa. 1977

T J Imperato, and C G Wong, and L J Chen, and R J Bolt

Pseudomonas aeruginosa was found to be able to hydrolyze bile sulfate. This property was observed when lithocholate sulfate was substituted for the sulfur source in the culture medium. The addition of MgSO4 to the medium inhibited the hydrolysis of the bile sulfate.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008095 Lithocholic Acid A bile acid formed from chenodeoxycholate by bacterial action, usually conjugated with glycine or taurine. It acts as a detergent to solubilize fats for absorption and is itself absorbed. It is used as cholagogue and choleretic. Lithocholate,Isolithocholic Acid,Acid, Isolithocholic,Acid, Lithocholic
D008278 Magnesium Sulfate A small colorless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of pre-eclampsia and eclampsia. It causes direct inhibition of action potentials in myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions. (From AMA Drug Evaluations Annual, 1992, p1083) Magnesium Sulfate, Heptahydrate,Heptahydrate Magnesium Sulfate,Sulfate, Magnesium
D011550 Pseudomonas aeruginosa A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection. Bacillus aeruginosus,Bacillus pyocyaneus,Bacterium aeruginosum,Bacterium pyocyaneum,Micrococcus pyocyaneus,Pseudomonas polycolor,Pseudomonas pyocyanea
D002793 Cholic Acids The 3 alpha,7 alpha,12 alpha-trihydroxy-5 beta-cholanic acid family of bile acids in man, usually conjugated with glycine or taurine. They act as detergents to solubilize fats for intestinal absorption, are reabsorbed by the small intestine, and are used as cholagogues and choleretics. Cholalic Acids,Acids, Cholalic,Acids, Cholic
D013431 Sulfates Inorganic salts of sulfuric acid. Sulfate,Sulfates, Inorganic,Inorganic Sulfates
