    Phenotypic and molecular characterization of luminous bacteria isolated from Izmir Gulf in Turkey: Vibrio harveyi TEM O5 and TEM S1 strains
    (2008) Omeroglu E.E.; Karaboz I.; Sukatar A.; Uzel A.; Sayan M.; Sanlidag T.
    Luminous bacteria were isolated from invertebrates and coastal seawater samples in the summer season 2004, from Izmir Gulf in Turkey. The seawater samples were concentrated by using 0.22-μ pore-sized nitrocellulose membrane filters. The concentrated seawater samples and intestinal contents of Holothuria tubulosa were inoculated on Seawater Complete (SWC) and BOSS media. The agar plates were incubated at 25°C for 48 h. After incubation, bioluminescent bacteria were isolated in a dark room, then purified and stored on a suitable medium. Bioluminescent isolates were identified with a polyphasic approach by using morphological, cultural, biochemical and molecular characteristics, in addition to 16SrDNA sequencing. Finally, the bioluminescent marine bacteria isolated from intestinal contents of H. tubulosa and seawater samples were identified as Vibrio harveyi TEM S1 and TEM O5 strains, respectively. © by PSP.

    Synthesis and Spectroscopic Studies of Phenanthroimidazole-Imine Derivatives and Evaluation of Their Antioxidant Activity
    (Springer New York LLC, 2018) Gülle S.; Erbaş S.Ç.; Uzel A.
    The phenanthroimidazole derivatives are used in the drug industry in large scale. In this study four new phenanthroimidazole-imine derivatives were synthesized and their spectroscopic studies as well as their antioxidant behaviors were examined. Structural analyses were made by FT-IR, 1H-NMR, 13C-NMR, LC-MS spectroscopy techniques. UV–vis absorption and emission spectroscopy techniques have been used to determine the photophysical characteristics of four newly synthesized phenanthroimidazoles. The maximum absorption and emission wavelengths, molar extinction coefficients (ε), singlet energy levels (Es), Stokes’ shift values (Δλ) of phenanthroimidazole-imine derivatives are given. Additionally, the antioxidant behavior of all compounds were investigated which the ascorbic acid used as standard molecule in present study. © 2017, Springer Science+Business Media, LLC.
