Figure Lengend Snippet: NI28 and several of the strains employed in this study, showing the presence of violacein (Peak #1–7.5 min) and a second peak (Peak #2–10.3 min) that is presumed to be deoxyviolacein. The solvent front (Peak S) is seen at 5.4 min. A plot generated using a commercially available violacein extracted from Janthinobacterium lividum is also provided for comparison and includes both Peak #1 and Peak #2.

Figure Lengend Snippet: D. violaceinigra str. NI28 grows faster than D. violaceinigra YIM 31327. ( A ) Image of each strain grown on NB agar plates for 24 and 60 hours. The upper and bottom regions are from the same plate. Note the more rapid colony development and violacein production by D. violaceinigra str. NI28. ( B ) Growth of both strains in NB media confirming that D. violaceinigra str. NI28 grows faster. The data for each strain was obtained from three independent cultures.

( B ) Violacein concentration within each culture at 24 and 48 hours, showing the rapid and high level violacein generation by D. violaceinigra str. NI28 as compared with the other strains. ( C ) The relative concentration of violacein based upon the culture density, illustrating that D. violaceinigra str. NI28 gave the greatest yields.

Figure Lengend Snippet: NI28 violacein. Two S. aureus strains were tested: ATCC 25923 and a clinical isolate. The initial CFU was determined just prior to addition of the violacein. The viability of the other samples was determined after a 24 hour exposure to the violacein at the concentrations listed, showing that the addition of 15 μM or greater violacein was bactericidal towards both pathogenic strains. The samples were prepared so that each had the same amount of DMSO (1.3%) added. The concentrations listed are based upon the commercial standard.
