Abstract:The ability of bamboo vinegar, produced from the pyrolysis of Gigantochloa scortechinii Gamble culms from Kedah, Malaysia, to inhibit the growth of micro-organisms was investigated using a laboratory-based assay. The inhibitory effects of cellulose discs treated with bamboo vinegar at 10%, 50% and 100% (no dilution) concentration on the growth of 7 fungal and 3 bacterial species was investigated. The two higher concentrations of bamboo vinegar showed growth-inhibiting effects against Aureobasidium pullulans (MBRB1-3), Chaetomium globosum (FPRL S70K), all three bacterial species and some effect with the other fungal species except Coriolus versicolor (FPRL 28A). The inhibition of growth followed a dose dependent response with the 100% concentration being the most effective. It is concluded that bamboo vinegar contains compounds that are inhibitory to microbial growth although specific evidence for activity at low concentrations, e.g., below 1% total organic compounds, was not obtained
