| Summary: | Tauco is one of fermented traditional food from Indonesia. The process of making tauco is
facilitated by spontaneous fermentation involving varieties of microbes. The process to produce
final tauco includes mold fermentation, brine fermentation and aging stage. This research is
intended to determine antibacterial activity from raw material, intermediate and the final product
of tauco. The extraction was carried out by sonication with R100% and temperature 250 C ?420 C for
20 minutes. Profiling of the extract was carried out by thin layer chromatography on silica gel GF254
and chloroform: ethyl acetate: methanol (8: 2: 0,4) for the mobile phase. Genistein and daidzein,
two main isoflavones of soybean were used as TLC markers. The result of disc diffusion showed
inhibition zone on Staphylococcus aureus, Escherichia coli and no activity against Candida albicans.
Furthermore, minimal inhibitory concentration (MIC) was measured using microdilution method.
The smallest MIC for Staphylococcus aureus is 5% and 2,5% for Pseudomonas aeruginosa from the
intermediate product.
