Antibacterlal and bactericidal activities of the bamb(,o extract against Stal ) hyloco ( :cus aureus ( S. aureus ) , Streptococcus mu 彦 ans ( S. mzatans ) and Candida albicans ( C. albic α ns ) were examined

The bactericidal activity was confirmed by MBC , which was nearly cqual to the MIC , against these mlcroorganism , The 5 % bamboo extract exhibited a marked antibacterial arld bactericidai activity against these microorganism . The bamboo extract contained more than 40 components , which were mainly Furans or Phenols. All of the mice were in normal health before and after the toxicjty tests , There was Ilo detectable amount of arsenic , lead or mercury in the bamboo extract . These results suggest that the bamboo extract can be used safely as an antibacterial agent or disinfectant comparable to conventional compounds used for those purpose .
