Studies on the Nutrition of Lactic Acid Bacteria

Part VI. An Improved Method for the Microbiological Determination of Niacinamide

Abstract

An assay method for the quantitative determination of niacinamide found in natural materials based on its essential nature for Lactobacillus fruclosus, a new species of lactic acid bacteria, is presented. The values obtained here are reproducible within ±6%. Recoveries of niacinamide added to the test materials could be made within ±6%.
