Pectinases are important for food and chemical industry that processes plant material, and also juice, textile and vine industry uses pectinases. They are able to modify and cause depolymerization in pectin chains. Fungi from genus Aspergillus are one of the most important sources of these enzymes. Vineyards contain plant material in decomposition and are a special place for pectinase producers. Many works screening pectinase producers were described in literature. However, better producers have been continuously found. This paper describes a screening of Aspergillus strains isolated from vineyards for pectinase production. The fungi strains (262) were evaluated in the screening methodology that studied the diameter of the pectin hydrolysis halo and the size of the colony in an agar culture media containing pectin as the sole carbon source. Four strains were selected for fermentation experiments. Aspergillus foetidus var. pallidus Ege-K-730 and Aspergillus aculeatus Ege-K-355 presented the highest pectinase production ratio, and Aspergillus foetidus var. pallidus K-635 and Aspergillus aculeatus K-398 presented the highest colony diameter. Aspergillus carbonarius CFTRI 1047 was used as a reference strain. In submerged fermentation (SbF), the strains Ege-K-730, Ege-K-355, Ege-K-635 and CFTRI 1047 produced the highest PG (polygalacturonase) and PMG (polymethylgalacturonase) levels, however, Ege-K-730 was the faster producer. In solid state fermentation (SSF), the strains Ege-K-730, Ege-K-635, Ege-K-398 and CFTRI 1047 produced the highest PG and PMG levels. In the experimental conditions, SSF was better than SbF for pectinase production.Item Algae of Turkey from the Herbarium Forsskålii(Academic Journals Inc., 2008) Taşkin E.; Pedersen P.M.The naturalist, Pehr Forsskål collected samples (phanerogams and cryptogams) from Estac (France), Turkey, Egypt and Yemen between 1761-1763. The collected plants were published in Flora Aegyptiaco-Arabica in 1775 including a list of 16 algal species from Turkey. In the present work, algae of Turkey from the Herbarium Forsskålii were studied. Several herbarium sheets have been lost and therefore, we were unable to identify some of Forsskål's collections. The aim of this research was to identify some of the remaining species and to annotate with regard to taxonomy and nomenclature. © 2008 Academic Journals Inc.Item A first report on the marine algal flora of Turkey: Pseudolithoderma adriaticum (Phaeophyceae, Lithodermataceae)(2008) Taşkin E.; Öztürk M.In this study, the brown alga Pseudolithoderma adriaticum (Hauck) Verlaque (Phaeophyceae, Lithodermataceae) is reported for the first time from Turkey. This species, with a distribution primarily in the Mediterranean Sea, was collected growing epilithically in the midlittoral zone (-0.5 m) in March 2007 from Ayvalik (Aegean Sea, Turkey). © by PSP.Item The enhancement of polygalacturonase and polymethylgalacturonase production on solid-state conditions by Aspergillus foetidus(2008) Taşkin E.; Eltem R.In this study, a previously isolated strain of Aspergillus foetidus Ege-K-635 producing highly active polygalacturonase and polymethylgalacturonase was used for improvement of enzyme production using solid-state conditions. To enhance the enzyme yield, the mixture of two substrates such as sugar beet pulp and wheat bran, having different ratios of carbon-nitrogen and moisture levels was used. Further the effect of the amount of inoculum was investigated. Physical parameters for the highest polygalacturonase and polymethylgalacturonase production under solid state conditions were determined on wheat bran: the sugar beet pulp (1:2) mixture substrate composition having a 31:1 carbon-nitrogen ratio with 8 × 106 spores/gram of dry substrate as the inoculum amount. Adequate moisture levels were 75% and 70% for polygalacturonase and polymethylgalacturonase, respectively. Under these conditions, the highest activities obtained were 385 ± 12.3 Ug-1 on the third day for polygalacturonase and 18.3 ± 3.2 Ug-1 on the second day for polymethylgalacturonase.

Soil samples of 62 sultana-type vine-yards from five locations (Alasehir, Manisa I, Manisa II, Manisa III and Izmir) were collected using the Brown's technique. The soil dilution technique was used for microfungi isolation. The mean microfungi number of 1 g fresh soil was counted to be 71 000 colony forming units (CFUs). A total of 66 species and 3 varieties belonging to 16 genera were encountered including Aspergillus, Penicillium, Cladosporium, Alternaria, Rhizopus, Trichoderma, Chaetomium, Chrysosponum, Dreschlera, Glomerularia, Gliocladium, Fusarium, Fusidium, Nectria, Spicaria, and Rhizomucor. Members of "Aspergillus section Nigri", generally known as black Aspergilli, dominated all locations and their incidence among all isolated fungi was 80.4 %. Aspergillus aculeatus was the most encountered species with 100 % ratio. It was followed by A. foetidus var. pallidus with 93.3 %, and A. awamori with 73.3 %. The highest microfungal diversity was found in location Manisa II (station Saruhanli) with indexes for biodiversity as Shannon (H) 3.28, Simpson's (D) 0.93 and Evenness (J) 0.96. This is the first extensive study carried out on biodiversity and microfungi flora of vineyard soils in Turkey.Item Taxonomy and description of the three marine cyanophycean algae from the Mediterranean Sea; [Türkiye'nin Akdeniz Kıyılarında Yayılış Gösteren Üç Mavi-Yeşil Alg Türünün Tanımlanması ve Taksonomisi](Central Fisheries Research Inst, 2010) Kurt O.; Ulcay S.; Taşkin E.; Öztürk M.In the present study, three marine Cyanophycean species from the Mediterranean are reported and described. These species were: Phormidium boryanum (Bory ex Gomont) Anagnostidis and Komárek (1988), Oscillatoria sancta f. caldariorum (Hauck) Lagerheim and Elenkin (1949) and Lyngbya anomala (C.B.Rao) Umezaki and Watanabe (1994), all members of the Oscillatoriales. The samples were collected from mid-littoral zones of Dikili Gulf (Aegean Sea, Turkey). The samples were kept in jars, fixed in 4% formaldehyde-sea water. The algae were identified under the microscope, mounted directly between lam and lamel. Current literature sources were used for the determinations. The photographs were taken using normal microphotography techniques. Data concerning distribution, morphology and ecology of each species are also given. © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey.Item Two brown algae from the eastern mediterranean sea: Microcoryne ocellata strömfelt and corynophlaea flaccida (C. Agardh) kützing(2010) Taşkin E.; Kurt O.; Cormaci M.; Furnari G.; Öztürk M.The finding of both Microcoryne ocellata Strömfeit and Corynophlaea flaccida (C. Agardh) Kützing from Turkey and North Cyprus (Mediterranean Sea) is reported. A comparison between both taxa, often confused by some authors, is given. This is the first documented record of the cold-temperate species M ocellata from the Mediterranean Sea. A taxonomic comment on C. flaccida, an endemic species in the Mediterranean Sea, is also given. © by PSP.Item Enhancement of solid state fermentation for production of penicillin g on sugar beet pulp(2010) Taşkin E.; Eltem R.; Soyak E.In this study, two local strains of Penicillium chrysogenum named EGEK458 and EGEK469 were selected for enhancement of Penicillin G (PenG) production under solid state fermentation (SSF) conditions. These two strains were selected among seven strains according to their fermentation yields for PenG production during previous tests under submerged fermentation conditions. Sugar beet pulp, an agro-industrial residue of the sugar industry, was used as an inert support for the first time in PenG production under SSF. In order to enhance the production of PenG, two points of moisture level and three concentration values of nutrients (impregnated in solid support), which are the key parameters in production of PenG, were compared. As the yields from solid and submerged fermentation were compared, 570U/g of PenG - almost 15 times higher quantities of its production vs. submerged conditions - were obtained under SSF conditions in 50 hours by the strain EGEK458. The conditions for the enhanced production of PenG were 65% moisture content with a four-fold concentrated nutrients impregnated solid support.Item Inhibitor activities of some seaweeds from the Aegean coast of Turkey(2011) Taşkin E.; Taşkin E.; Öztürk M.In this study methanolic extracts of four seaweeds belong to Phaeophyceae (Petalonia fascia, Stypocaulon scoparium) and Chlorophyceae (Cladophora prolifera, Codium fragile) that were collected from the Aegean coast of Turkey have been studied for their inhibitor activity against pathogenic microbes (Staphylococcus aureus, Staphylococcus epidermidis, Salmonella typhimurium, Enterobacter aerogenes, Escherichia coli, Enterococcus faecalis and Escherichia coli O157:H7), in vitro. Against the extracts of all the tested marine algae, S. aureus was the most sensitive bacteria since it was inhibited by most of the extracts. On the other hand, the highest inhibitor activity was shown to Enterobacter faecalis by the extract of Codium fragile. Whereas, the growth of Salmonella typhimurium and Enterobacter aerogenes were not inhibited by any of the extracts.Item First report of the alien brown alga Botrytella parva (Takamatsu) H.-S. Kim (Chordariaceae, Phaeophyceae) from the eastern Mediterranean Sea(2012) Taşkin E.; Pedersen P.M.Botrytellaparva (Chordariaceae, Phaeophyceae) is reported for the first time from the eastern Mediterranean Sea. The species was collected from the Dardanelles (Sea of Marmara, Turkey) in the sublittoral zone. Data concerning its habitat, morphology and worldwide distribution are presented. The justification for transfer of Polytretus reinboldii to Botrytella is discussed, and we found morphological arguments to resurrect the generic name Polytretus. A key to the species of Botrytella and Polytretus is provided.Item New mediterranean biodiversity records (december 2012)(Hellenic Centre for Marine Research, 2012) Thessalou-Legaki M.; Aydogan O.; Bekas P.; Bilge G.; Boyaci Y.O.; Brunelli E.; Circosta V.; Crocetta F.; Durucan F.; Erdem M.; Ergolavou A.; Filiz H.; Fois F.; Gouva E.; Kapiris K.; Katsanevakis S.; Kljajić Z.; Konstantinidis E.; Konstantinou G.; Koutsogianopoulos D.; Lamon S.; Mačić V.; Mazzete R.; Meloni D.; Mureddu A.; Paschos I.; Perdikaris C.; Piras F.; Poursanidis D.; Ramos-Esplá A.A.; Rosso A.; Sordino P.; Sperone E.; Sterioti A.; Taşkin E.; Toscano F.; Tripepi S.; Tsiakiros L.; Zenetos A.This paper presents records extending or confirming the distribution of Mediterranean species.
