Fifty three microbes, mainly fungal genera, were isolated from sixteen Mejus of different region. From those collected isolates, Meju was manufactured and assayed for the activities of amylase and protease. Correlations between sensory evaluation and color measurement were investigated with Kanjang (soy sauce) prepared by each pure inoculation. Color of Kanjang was quite various depedning on fungal genera, but the taste was not quite related with the activity of amylase or protease. This fact might mean that taste of Kanjang depended on the complicate mechanistic action of enzyme for the substrate involved in the soybean hydrolysis. Thus, the taste of Kanjang origenated from Korean traditional Meju seems to belong to complex flora of participated fungal genera as well as Bacillus. sp.
