Screening antagonistic bacteria against S. aureus Sa25 using pQS series. Bacterial lawn prepared with pQS1 (A) and pQS3 (B) transformants of S. aureus Sa25 exhibits the zone of growth inhibition and QQ in the presence of antagonistic bacteria. Plates show glowing fluorescence under UV light (bottom plates of (A) and (B)). Test bacteria streaked on S. aureus Sa25 lawn include L. lactis (test 1), S. aureus Sa25 (test 5), S. aureus Sa27 (test 6), Bacillus pumilus (test 7, 69, 70, 75, 77, 84), B.altitudinis (test 8), B. subtilis (test 11 and 63), Aerococcus viridans (test 32), S. chromogenes (test 43, 53, and 54), S. saprophyticus (test 45), Bacillus species (test 65), S. pasteuri (test 71), and unknown species (test 83)
