The diversity of archaeal strains from six hypersaline environments in Turkey was analyzed by comparing their phenotypic characteristics and 16S rDNA sequences. Thirty-three isolates were characterized in terms of their phenotypic properties including morphological and biochemical characteristics, susceptibility to different antibiotics, and total lipid and plasmid contents, and finally compared by 16S rDNA gene sequences. The results showed that all isolates belong to the family Halobacteriaceae. Phylogenetic analyses using approximately 1,388 bp comparisions of 16S rDNA sequences demonstrated that all isolates clustered closely to species belonging to 9 genera, namely Halorubrum (8 isolates), Natrinema (5 isolates), Haloarcula (4 isolates), Natronococcus (4 isolates), Natrialba (4 isolates), Haloferax (3 isolates), Haloterrigena (3 isolates), Halalkalicoccus (1 isolate), and Halomicrobium (1 isolate). The results revealed a high diversity among the isolated halophilic strains and indicated that some of these strains constitute new taxa of extremely halophilic archaea.

Characterization of bacteriocins from two Lactococcus lactis subsp lactis isolates
Akcelik, O; Tukel, C; Özcengiz, Gülay; Akcelik, M (Wiley, 2006-03-01)
In this study, bacteriocins from two Lactococcus lactis subsp. lactis isolates from raw milk samples in Turkey designated OC1 and OC2, respectively, were characterized and identified. The activity spectra of the bacteriocins were determined by using different indicator bacteria including Listeria, Bacillus and Staphylococcus spp. Bacteriocins were tested for their sensitivity to different enzymes, heat treatments and pH values. Loss of bacteriocin activities after alpha-amylase treatment suggested that they...
A molecular phylogeny of Salvia euphratica sensu lato (Salvia L., Lamiaceae) and its closely related species with a focus on the section Hymenosphace
Dizkırıcı, Ayten; CELEP, FERHAT; Kansu, Cigdem; KAHRAMAN, AHMET; Doğan, Musa; Kaya, Zeki (2015-12-01)
To investigate the phylogenetic relationships of Salvia euphratica sensu lato and its closely related species with a focus on the section Hymenosphace, we screened five different regions; one nuclear ribosomal DNA region (Internal Transcribed Spacer, ITS) and four chloroplast DNA regions [trnT-trnL intergenic spacer (IGS), trnL intron, trnL-trnF IGS and trnV intron]. Based on 19 sequences of 7 Salvia taxa produced in the study and different number of sequences obtained from GenBank, our results supported la...
Determination of esterase enzyme polymorphism in house fly (Musca domestica L.) populations in Turkey
TAŞKIN, VATAN; Taskin, Belgin Gocmen; KÜÇÜKAKYÜZ, KÖKSAL; Kence, Meral (2011-01-01)
The objective of this study was to determine esterase enzyme polymorphism in 16 natural Musca domestica L. populations from the Aegean and Mediterranean regions of Turkey by using the native polyacrylamide gel electrophoresis (PAGE) technique. The high level of genetic variation among populations and species make esterase enzymes an important tool for analyzing genetic differentiation and evolutionary relationships in insects. In the present study, 22 a-esterase bands were detected by using a-naphthylacetat...
Composition of eggs and larvae of fish and macrogelatinious zooplankton in Sinop Region (The Central Black Sea) during 2002
Satilmis, Hasan Huseyin; Bat, Levent; Ozdemir, Zekiye Birinci; Ustun, Funda; Sahin, Fatih; Kıdeyş, Ahmet Erkan; Erdem, Yakup (2006-01-01)
This study was carried out in order to determine abundance and distribution of macrogelatinous organisms (Aurelia aurita, Pleurobranchia pileus, Mnemiopsis leidyi ve Beroe ovata) with respect to fish egg and larvae in Sinop region in 2002. Three stations were selected this region and plankton tows were made both verticallly and horizontally. In study the ctenophores M. leidyi between January and September, and B. ovata between August and December period were appeared. The cnidarian Aurelia aurita and the ct...
Identification and Characterization of 33 Bacillus cereus sensu lato Isolates from Agricultural Fields from Eleven Widely Distributed Countries by Whole Genome Sequencing
Zervas, Athanasios; Aggerbeck, Marie Ronne; Allaga, Henrietta; GÜZEL, MUSTAFA; Hendriks, Marc; Jonuskiene, IIona; Kedves, Orsolya; Kupeli, Ayse; Lamovsek, Janja; Muelner, Pascal; Munday, Denise; Namlı, Şahin; Samut, Hilal; Tomicic, Ruzica; Tomicic, Zorica; Yeni, Filiz; Zghal, Raida Zribi; Zhao, Xingchen; Sanchis-Borja, Vincent; Hendriksen, Niels Bohse (2020-12-01)
The phylogeny, identification, and characterization of 33 B. cereus sensu lato isolates originating from 17 agricultural soils from 11 countries were analyzed on the basis of whole genome sequencing. Phylogenetic analyses revealed all isolates are divided into six groups, which follows the generally accepted phylogenetic division of B. cereus sensu lato isolates. Four different identification methods resulted in a variation in the identity of the isolates, as none of the isolates were identified as the same...
