The application of 2,6-dichlorophenolindophenol, an oxido-reducing indicator, to a method for the microbiological cup-plate assay of thiamine with Lactobacillus fermenti was effective for enhancing the contrast between the growth zones of the organism and the area of non-visible growth. The results obtained by this technique were further compared with those of the original method. The zones of exhibition were reproducible and there was no significant difference in their sizes between both methods. The highest probable error was a little higher than the original assay method. This indicator may be available for increasing the visibility of the growth zones without a great lowering of the precision.
