This paper described the influence on the growth of lactic acid bacteria, acetic acid bacteria, and yeast, of samac bark, samac fruit, samac leaf, and duhat bark which are added to basi (Philippine sugarcane wine).1. The aqueous extract of samac bark greatly inhibited the growth of lactic acid bacteria and acetic acid bacteria, but the growth of yeast was greatly increased by the aqueous extract. From this, it is presumed that samac bark prevents the acidification of basi by lactic acid bacteria and acetic acid bacteria, and it accelerates the alcohol fermentation by yeast.2. The aqueous extract of samac fruit not only inhibited the growth of lactic acid bacteria, but it also inhibited the growth of yeast. From these results, it is presumed that samac fruit prevents the acidification of basi, and it also inhibits the alcohol fermentation.3. The aqueous extract of samac leaf promoted the growth of yeast, but it caused little growth inhibition of lactic acid bacteria and acetic acid bacteria. So it is presumed that the samac leaf has little prevention effect on the acidification of basi.4. The aqueous extract of duhat bark greatly inhibited the growth of acetic acid bacteria, and it is presumed that it prevents the acidification of basi. It also inhibited the growth of yeast, and it is presumed that it inhibits the alcohol fermentation of basi.5. The polyphenol content of each sample was measured, and all samples contained a great deal of polyphenol. It is presumed that the polyphenol inhibits the growth of microorganisms.6. The aggregated cells of the lactic acid bacteria, acetic acid bacteria, and yeast which were grown in the medium with the aqueous extract of samples were observed, and the surface of these cells were covered with granular matter. These adhered granular matter on the surface of cells are presumed to be related to the growth inhibition of the microorganisms.
