B.c: Bacillus cereus (KCTC 1012), S.a: Staphylococcus aureus subsp. sureus (KCTC 1927), B.s: Bacillus subtillis subsp. Spizizenii (KACC 14741), K.r: Kocuria rhizohhila (KACC 14744), M.l: Micrococcus luteus (KACC 14819), E.cl: Enterobacter cloacae (KACC 11958), K.p: Klebsiella pneumonie (KACC 14816), E.c: Escherichia coli (KCTC 1924), P.a: Pseudomonas aeruginosa (KCTC 1750), P.v: Proteus vulgaris (KCTC 2433), S.c: Saccharomyces cerevisiae (KCTC 7913), P.j: Pichia jadnii (KCTC 7293), C.a: Candida albicans (KCTC 7965).

The MIC value against bacteria was determined through the serial two-fold dilution method. The growth of the bacteria was evaluated by the degree of turbidity of the culture with the naked eye in twelve hours.
