Extreme levels of hidden diversity in microscopic animals (Rotifera) revealed by DNA taxonomy
(Academic Press, 2009)Knowledge and estimates of species richness at all scales are biased both by our understanding of the evolutionary processes shaping diversity and by the methods used to delineate the basic units of diversity. DNA taxonomy ... -
Factors affecting the coaggregation ability of vaginal Lactobacilli with Candida spp.
(Springer, 2009)In this study, the capacity of 30 strains of lactobacilli to coaggregate with Candida albicans ATCC 10239, C. albicans AJD 180 and Candida krusei ATCC 6258 were studied in vitro. A marked coaggregation with C. albicans was ... -
Some factors affecting the autoaggregation ability of vaginal lactobacilli isolated from Turkish women
(Institut za biološka istraživanja Siniša Stanković, 2009)In this work, autoaggregation and factors involved in the autoaggregation ability of vaginal lactobacilli were studied. The autoaggregation ability of 28 lactobacilli strains was positive. The effects of various factors ... -
Survey of moss-dwelling bdelloid rotifers from middle Arctic Spitsbergen (Svalbard)
(SPRINGER, 2010)A survey of bdelloid rotifers from moss and lichen samples collected in the middle Arctic tundra subzone of Spitsbergen (Svalbard) revealed an unexpected high species richness of 52 taxa, of which 18 fully identified species ... -
Assessment of potential probiotic properties of lactobacillus spp., lactococcus spp., and pediococcus spp. strains isolated from kefir
(Wiley, 2010)In this study, the metabolic activities (in terms of quantities of the produced lactic acid, hydrogen peroxide, and exopolysaccharides) of 8 strains of Lactobacillus spp., Lactococcus spp., and Pediococcus spp., were ... -
Ten additions to the rotifer fauna of Turkey
(TUBITAK Scientific & Technical Research Council Turkey, 2010)Ten monogonont rotifer species new for the Turkish fauna discovered in 2007 are discussed: Cephalodella delicata Wulfert, C. cf. forceps Donner, C. misgurnus Wulfert, Dipleuchlanis propatula (Gosse), Encentrum limicola ... -
Temperature and salinity as interacting drivers of species richness of planktonic rotifers in Turkish continental waters
(PAGEPRESS PUBL, 2010)Salinity and temperature are known to be important factors driving species richness and species composition in inland waters, but their effect and interaction are still not completely clear. In this paper we examine their ... -
Zooplankton community structure of Asartepe Dam Lake (Ankara, Turkey)
(Central Fisheries Research Institute, 2010)Zooplankton community structure of Asartepe Dam Lake was examined by collecting samples in three different seasons (Autumn 2007, Spring and Summer 2008). Rotifera was found the dominant group with 43 species, followed by ... -
Annual change of the testosterone hormone in male white goats
(Elsevier Ltd., 2011)In this research, changes of testosterone hormone in the blood serum of 9 male (3 of age 2 and 6 of age 4) White goats have been studied for a duration of one year. Analyses performed show that the general monthly averages ... -
Cryptic diversity in the genus Adineta Hudson & Gosse, 1886 (Rotifera: Bdelloidea: Adinetidae): a DNA taxonomy approach
(Springer, 2011)Cryptic species are continuously discovered in rotifers using different methods to delineate these units of diversity. DNA taxonomy is the most effective method taxonomists have to untie potential cryptic taxa. Here, we ... -
Influence of gastrointestinal system conditions on adhesion of exopolysaccharide-producing Lactobacillus delbrueckii subsp. bulgaricus strains to Caco-2 cells
(INST Tecnologia Parana, 2011)This study aimed to assess the transit tolerance of potential probiotic dairy Lactobacillus strains in human uppergastrointestinal tract in vitro, and to evaluate the effect of EPS production on the viability and adhesion ... -
Aggregation and hydrophobicity properties of 6 dairy Propionibacteria strains isolated from homemade Turkish cheeses
(2012)In the present study, 6 dairy Propionibacterium strains were assessed with regard to their hydrophobic characteristics and their autoaggregation and coaggregation abilities since these traits have been shown to be indicative ... -
Investigating hydrophobicity and the effect of exopolysaccharide on aggregation properties of dairy propionibacteria isolated from Turkish homemade cheeses
(2012)Propionic acid bacteria have been used widely as starter cultures. However, their potential as probiotics has received little attention. The ability to auto- and coaggregate is a desirable property for probiotics in ... -
Acid-bile, antibiotic resistance and inhibitory properties of propionibacteria isolated from Turkish traditional home-made cheeses
(Elsevier Ltd., 2012)In this study, a total of 29 Propionibacterium spp. were isolated from traditional home-made Turkish cheese samples. As a result of the identification, isolates were identified as Propionibacterium freudenreichii subsp. ... -
Research on some factors influencing acid and exopolysaccharide produced by dairy propionibacterium strains isolated from traditional homemade Turkish cheeses
(International Association for Food Protection, 2012)In this study, a total of 32 isolated strains and 5 reference strains of dairy propionibacteria were analyzed for acid and exopolysaccharide (EPS) production in skim milk and yeast extract–lactate broth (YEL) media in order ... -
A checklist of Turkish rotifers
(Tubitak, 2012)In a book chapter containing the fi rst checklist and distribution of Turkish rotifers, published in 1999, were listed 167 taxa. The second checklist, published in 2004, reported 229 rotifer taxa in Turkey. During the 7 ... -
Terrestrial bdelloid rotifers from Erzurum (eastern part of Turkey)
(TÜBİTAK, 2013)There has been a growing interest in studies of the macroecology and biogeography of microorganisms (smaller than 2 mm) in recent years; however, knowledge of the diversity patterns of these organisms is inadequate. The ... -
Relationship between gastrointestinal tolerance and exopolysaccharide production of propionibacteria strains under different pH and bile conditions
