MICROBIOLOGICAL ASSAY FOR THIAMIN USING LACTOBACILLUS VIRIDESCENS

Automated microbiological assay of thiamin in serum and red cells.

AIMS To develop a sensitive, direct, automated method for the measurement of serum and red cell thiamin. METHODS A microbiological assay using a chloramphenicol resistant strain of Lactobacillus fermenti as the test organism was developed.
