Overall objective of the study was assessment for freshness parameters gilthead seabream (Sparus aurata). The determined by two conventional method (i.e. Minolta color measurement method) compared with a novel machine vision technology (i.e image analysis method). quality characteristics related to fresh fish are traditionally based on measurements whole using method. This aimed compare use see whether seafood can be measured more accurately. Our proved exact and reliable results in...
Abstract A massive die-off of benthic suspension feeders (BSF) covered by large amounts sediments was observed along Prince Islands coasts (north-eastern Sea Marmara) in August 2015. Alcyonarians, pennatulaceans, bivalves and sponges were severely affected. Many BSF probably died from burial clogging their feeding respiratory apparatus. Of the gorgonian colonies, 66 ± 34% (mean SD) dead, while 15 16% displayed recent necrosis on colony surface. In addition, histopathological microbial...
Chemical investigation of the marine sponge Ircinia oros yielded four linear furanosesterterpenoids, including known metabolites ircinin-1 (1) and ircinin-2 (2) two new compounds, ircinialactam E (3) F (4). Their chemical structures were elucidated by using a combination [α]D, NMR, HRMS, FT-IR spectroscopy. The absolute configuration C-18 in compounds 1-3 was identified as R electronic circular dichroism (ECD) spectroscopy coupled with time-dependent density functional theory calculations....
This study compiled the data from previous papers emphasizing sponge species on Turkish coasts. In total, 131 belonging to 46 families have been reported: 82 Aegean Sea, 63 Sea of Marmara, 51 Levantine and 13 Black Sea. Among these species, 3 are new records for marine fauna Turkey: Rhizaxinella elongata, Axinyssa digitata, Terpios gelatinosa. Raspalia viminalis is a record Marmara. The morphological distributional features presented. addition, checklist reported coasts date provided.
Sponge species collected along the coasts of Sea Marmara in 2012-2013 were identified.A total 30 belonging to 21 families found, which four (Ascandra contorta, Paraleucilla magna, Raspailia (Parasyringella) agnata and Polymastia penicillus) are new records for eastern Mediterranean, while six [A.contorta, P. Chalinula renieroides, penicillus, R. (P.) Spongia (Spongia) nitens] marine fauna Turkey 12 Marmara.Sponge specimens generally shallow water, but two (Thenea muricata Rhizaxinella...
Data on deep sea leptostracans (Crustacea: Phyllocarida: Leptostraca) are still scarce in many parts of the world. In last few years, several species Nebalia Leach, 1814, have been reported from eastern Mediterranean; however, there no reports waters deeper than 100 m. Samples collected recently Gökçeada, Turkey-at depths 680-820 m Aegean Sea, Mediterranean-included abyssicola Fage, 1929. This is first record for study area and one known records this species. Specimens described figured to...
To better predict population evolution of invasive species in introduced areas it is critical to identify and understand the mechanisms driving genetic diversity structure their native range. Here, we combined analyses mitochondrial COI gene 11 microsatellite markers investigate both past demographic history contemporaneous area gastropod Tritia neritea, using Bayesian skyline plots (BSP), multivariate clustering. The BSP framework revealed expansions, dated after last glacial maximum....
A total of 1127 crustacean specimens was sampled from five stations in the deep-sea depressions Sea Marmara (>1000 m deep). Calocaris macandreae Bell, 1853 by far dominant species at all stations. Polycheles typhlops C. Heller, 1862 and Sergestes robustus Smith, 1882 were found low numbers.
The type II fatty acid pathway (FAS-II) is a validated target for antimicrobial drug discovery. In continuation of our efforts to discover natural inhibitors the enoyl-ACP reductase enzyme from P. falciparum (PfFabI), M. tuberculosis (InhA) and E. coli (EcFabI), we studied n-hexane, CHCl3 aq. MeOH extracts Agelas oroides sponge. An activity-directed fractionation based on PfFabI inhibition all three afforded six pure metabolites, 24-ethyl-cholest-5α-7-en-3β-ol (1),...
