Benthic Diatom Blooms of Blue spp. in the Mediterranean Sea.

Blue species are marine benthic pennate diatoms able to synthesize a blue-green water-soluble pigment, like marennine produced by Simonsen. New species of synthetizing blue pigments were recently described (, , and ). Their marennine-like pigments have allelopathic, antioxidative, antiviral and antibacterial properties, which have been demonstrated in laboratory conditions.

Amphiphilic Poly(vinyl alcohol) Membranes Leaving Out Chemical Cross-Linkers: Design, Synthesis, and Function of Tailor-Made Poly(vinyl alcohol)-b-poly(styrene) Copolymers.

Tailor-made poly(vinyl alcohol)-b-poly(styrene) copolymers (PVA-b-PS) for separation membranes are synthesized by the combination of reversible-deactivation radical polymerization techniques. The special features of these di-block copolymers are the high molecular weight (>70 kDa), the high PVA content (>80 wt%), and the good film-forming property. They are soluble only in hot dimethyl sulfoxide, but by the "solvent-switch" technique, they self-assemble in aqueous media to form micelles.

Biodiversity of carapace epibiont diatoms in loggerhead sea turtles ( Linnaeus 1758) in the Aegean Sea Turkish coast.

Background: The Aegean Sea coast of Turkey hosts one of the most important nesting grounds for loggerhead sea turtles () in the Mediterranean Sea. Previous studies have revealed that the sea turtle carapace provides favourable conditions for various epibiontic organisms. Epibionts occurring on the carapace have been examined from different locations in the oceans.

Complete chloroplast genome of the tiny marine diatom (Bacillariophyta) from the Adriatic Sea.

We report the chloroplast genome sequence of , a tiny araphid pennate diatom collected from the Adriatic Sea. The 160,994-bp . genome displays a quadripartite structure and its gene repertoire resembles those of other diatom chloroplast genomes.

pH-Triggered Membrane in Pervaporation Process.

Dehydration of binary methyl acetate-water mixtures under neutral, acidic, and basic conditions was carried out by using PERVAP composite membranes based on polyvinyl alcohol and poly(1-vinylpyrrolidone--2-(dimethylamino)ethyl methacrylate) P(VP--DMAEMA). The effects of an acid (HCl) and a base (NaOH) on the separation performance of the membrane during the pervaporation process were investigated. The pH-responsive nature of membranes has been confirmed by swelling tests and analysis of the chemical structure of polymeric membranes.
