Biotransformation of chenodeoxycholic acid by Pseudomonas species NCIB 10590 under anaerobic conditions.

abstract：:14C-labeled oleic acid and (3)H-labeled monoether in a bile salt solution were perfused through three types of plastic tubing. Large proportions of lipid were lost to the walls of silicone rubber and polyvinyl chloride tubes. The major portion of the lipid lost was recoverable only when chloroform-methanol was perfuse...
