Only the bacterial strains with antimicrobial activity against at least three indicator strains were listed.
Antimicrobial activities were tested against Escherichia coli (Ec), Pseudomonas aeruginosa (Pa), Bacillus subtilis (Bs), Staphylococcus aureus (Sa), Candida albicans (Ca), Vibrio anguillarum (Va), and Vibrio parahaemolyticus (Vp).
Symbols of inhibition degree against indicator strains: (-), no inhibition; (+), 11 < inhibition zone < 13 mm; (++), 13 ≤ inhibition zone < 16 mm; (+++), 16 ≤ inhibition zone < 22 mm; (++++), inhibition zone ≥ 22 mm.
