The cup-plate method was proved to give a sharp and clear growth zone of Lactobacillus fermenti for thiamine determination. It was recognized a linear relationship between the diameter of growth zone and logarithm of the concentration of thiamine over a wide range of 0.1 to 1Oμg per ml. The statistical analysis of the results revealed that the maximum error of cup-plate method using 5 plate mounted only to 20%, and it is supposed to give most reproducible result among other methods, though it is somewhat inferior in sensibility. However, in case of its application to biological materials, a precaution should be taken against the possible existence of interfering factors in them.
