| Abstract | Biological fermented products are obtained from the fermentation of vegetables, fruits and sugar mediated by microorganisms. The objective of this research was to study the antimicrobial activity of three biological fermented products derived from Northeastern Thai vegetables, namely Careya sphaerica Roxb., Cratoxylum formosumDyer and Eugenia grata(Wight) S.N. Mitra var. gratum. Each of them was prepared according to the local wisdom process. After 1 month of fermentation, the products were investigated for antimicrobial activity against 7 microorganisms, i.e. Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis, Escherichai coli, Salmonella typhi, Pseudomonas aeruginosa and Candida albicansby agar disc diffusion method. The antimicrobial activity of the aqueous extracts of these plants was also compared. Results showed that the biological fermented product and the extract of C. sphaericahad the effect on B. subtilis, S. aureus,and S. typhi,while the biological fermented product of C. sphaerica had the additional effect on E. coliand P. aeruginosa.Both the biological fermented product and the extract of E. gratahad the activity against S. typhi, but the former showed more inhibitory activity on B. subtilisand S. aureus.The extract of C. formosumhad the activity on S. aureusbut its biological fermented product did not. From the present, it is likely to conclude that the biological fermented products of Northeastern Thai vegetables that showed the appreciably antimicrobial activity were C. sphaericaand S. gratum,respectively. In detection of the fermentation participating microorganism, Lactobacillus caseiwas found and it existed in the products for about 2-3 weeks of fermentation. These biological fermented products were in the absence of microbial pathogens e.g., S. aureus, E. coli, S. typhi andClostridium perfringens.However fungi were over the limit. |
