Microbial Production of Ursodeoxycholic Acid from Lithocholic Acid by Fusarium equiseti M41

Preparation of ursodeoxycholic acid from 7-ketone lithocholic acid by stereoselective electroreduction

Background: Ursodeoxycholic acid (UDCA) is an important clinical drug in the treatment of liver disease. In previous work, ursodeoxycholic acid was prepared by traditional organic synthesis. The preparation of ursodeoxycholic acid through an electrochemical method with higher stereoselectivity and environmental friendliness is described herein. Results: Dimethyl sulfoxide (DMSO), dimethylformam...

Production of bile duct hyperplasia and gallstones by lithocholic acid.

Ursodeoxycholic acid

Ursodeoxycholic acid is an epimer of chenodeoxycholic acid (DB06777). It is a mammalian bile acid found first in the bear and is apparently either a precursor or a product of chenodeoxycholate. Its administration changes the composition of bile and may dissolve gallstones. It is used as a cholagogue and choleretic. [PubChem] Indication: The drug reduces cholesterol absorption and is used to dis...

Antibiotic produced by Fusarium equiseti NRRL 5537.

Fusarium equiseti NRRL 5537 grown on an autoclaved white corn grit medium for 3 to 4 weeks at room temperature produced a substance in excess of 5 g/kg of substrate that inhibited some gram-positive bacteria including mycobacteria. Most Bacillus subtilis, Mycobacterium phlei, and Staphylococcus aureus strains were inhibited when 1 mug of the antibiotic per ml was incorporated into the culture m...

Microbial Propionic Acid Production

Propionic acid (propionate) is a commercially valuable carboxylic acid produced through microbial fermentation. Propionic acid is mainly used in the food industry but has recently found applications in the cosmetic, plastics and pharmaceutical industries. Propionate can be produced via various metabolic pathways, which can be classified into three major groups: fermentative pathways, biosynthet...
