Folic Acid Casei Medium 100G

Folic Acid Casei Medium is recommended for microbiological assay of folic acid in blood serum using Lactobacillus casei ATCC 7469 as test organism. The test organism used in vitamin assay generally requires three media, i.e. a culture maintenance medium, a inoculation medium and a test medium. Folic Acid Casei Medium contains all the essential nutrients for the growth of Lactobacillus casei except folic acid. Therefore additions of folic acid in specified increasing concentrations gives a similar increase in the growth response of the Lactobacillus casei.
