Asparagus Cochinchinensis is known to ameliorate respiratory disease. We evaluated the antimicrobial activity of non-fermented and fermented A. cochinchinensis using lactic acid bacteria and investigated the physicochemical characteristics of the fermented A.cochinchinensis. Non-fermented A.cochinchinensis showed lower levels of antimicrobial activity than the fermented A.cochinchinensis. Ethyl acetate (EtOAc) extracts of the fermented A. cochinchinensis showed antimicrobial activities against the indicator strains at lower minimum inhibitory concentration (MIC). The MIC of the EtOAc extract of non-fermented A. cochinchinensis against Escherichia coli, Staphylococcus epidermidis, and Stphylococcus aureus were 100, 75, and 100 mg/ml. In contrast, the MIC of the EtOAc extract of ACLM was 25 mg/mL against E. coli. The MIC of the EtOAc extract of ACLS was 12.5 mg/mL against S.epidermidis, and the MIC of the EtOAc extract ofACLP was 12.5 mg/mL against S.aureus. The viable cell number, pH, and acidity of A. cochinchinensis fermented by Lactobacillussakei 383 were similar to those of A. cochinchinensis fermented by Leuconostocmesenteroides 4395, but were different from those of A. cochinchinensis fermented by Lactobacillus.plantarum KCCM 11322. These results suggested that the fermented A. cochinchinensis by lactic acid bacteria may be a good candidate for application to ameliorate respiratory disease.
