Turkish Journal of Chemistry
Pleurotus sapidus} basidiospores immobilized onto Ca-alginate beads were used for the removal of cadmium and mercury ions from aqueous solutions. The biosorption of Cd(II) and Hg(II) ions on the alginate beads and both immobilized live and heat inactivated fungal mycelia of Pleurotus sapidus} was studied from aqueous solutions in the concentration range of 30-500 mg L^{ - 1}. The biosorption of Cd(II) and Hg(II) ions by the alginate and both live and heat inactivated immobilized preparations increased as the initial concentration of the ions increased in the medium. Maximum biosorption capacity for immobilized live and heat inactivated fungal mycelia of …
Pyridine And Benzene Templated Potential Peptidomimetics, Kadi̇r Dabak
Pyridine And Benzene Templated Potential Peptidomimetics, Kadi̇r Dabak
Turkish Journal of Chemistry
This study provides a new approach for the synthesis of pyridine and benzene templated potential peptidomimetics. By the attachment of various amino acid side chains in different combinations on the pyridine template at the 2- and 3- positions and on the benzene core at 1,2,4 positions, different peptidomimetics may be obtained. Arg-10, Leu-11 and Tyr-13 amino acid side chain mimics and their precursors were attached to the pyridine and benzene core with a special arrangement to produce potential peptidomimetics of omega-conotoxin MVIIA.

Effects Of Indoleacetic Acid And Kinetin On Lipid Peroxidation Levels In Various Rat Tissues, İsmai̇l Çeli̇k, Yasi̇n Tülüce, Necati̇ Özok
Turkish Journal of Biology
This study was carried out to investigate whether plant growth regulators (PGRs) could affect lipid peroxidation (Malondialdehyde = MDA level) in erythrocyte, muscle, liver, heart and kidney tissue. Eighteen Sprague-Dawley albino rats were divided into three experimental groups: control and PGR-treated (indoleacetic acid and kinetin). Seventy-five ppm of PGRs, indoleacetic acid (IAA), and kinetin were administered orally to 6 rats ad libitum for 25 days. The hormone treatments caused different effects on the level of malondialdehyde (MDA) to those of the control rats. According to the results, while liver and kidney MDA levels were increased significantly by IAA administration in …
Antimicrobial Peptides: A Potential Therapeutic Alternative For The Treatment Of Fish Diseases, Ali̇ye Sarmaşik
Antimicrobial Peptides: A Potential Therapeutic Alternative For The Treatment Of Fish Diseases, Ali̇ye Sarmaşik
Turkish Journal of Biology
Fish losses from infectious diseases are a significant problem in aquaculture worldwide. However, peptide antibiotics show potent activity against a broad range of pathogens including fish pathogens. Therefore, the ability of antimicrobial peptides to protect fish against infections caused by fish pathogens clearly shows the potential for utilisation of antimicrobial peptides for the treatment of fish diseases. The strategy of overexpressing the antimicrobial peptide genes in transgenic fish may provide a method of decreasing fish disease problems in aquaculture.

Some Properties Of Crude Carboxymethyl Cellulase Of Aspergillus Niger Z10 Wild-Type Strain, Gökhan Coral, Burhan Arikan, M. Ni̇sa Ünaldi, Hati̇ce Güvenmez
Turkish Journal of Biology
A carboxymethyl cellulase enzyme was prepared from a wild type strain of Aspergillus niger Z10. Analyses of the enzyme preparation by SDS-PAGE revealed two protein bands showing cellulolytic activity. The molecular weight of these bands was estimated to be around 83,000 and 50,000. The optimum temperature of the enzyme was observed to be around 40 °C. It was found that the enzyme's activity has a broad pH range between 3 to 9 and 41.2% of the original activity was retained after heat treatment at 90 °C for 15 min.

Turkish Journal of Biology
In this study, the production of Poly-b-hydroxybutyrate (PHB) was determined in 1 Rhizobium japonicum, 6 Rhizobium cicer, 8 Rhizobium spp. and Bradyrhizobium japonicum USDA 110. The content of according to dry cell weight was determined to be 1.38-40.0%. In our study, Rhizobium spp. 2426, which produced the highest percentage yield of PHB, and Rhizobium spp. 640, which produced the intermediate percentage yield of PHB, were first selected among all the strains, and then the effect of different carbon and nitrogen sources on PHB production in these strains was tested. While the strains produced less PHB in yeast extract mannitol (YEM) …

Epipelic And Epilithic Algae Of The Yedigöller Lakes (Erzurum-Turkey), Bülent Şahi̇n
Turkish Journal of Biology
The epipelic and epilithic algae of the Yedigöller Lakes were studied qualitatively between June and September 2001. As a result 90 taxa (43 belonging to Bacillariophyta, 33 to Chlorophyta, 11 to Cyanophyta and three to Euglenophyta) were determined. Based on the algal community composition, the Yedigöller Lakes can be characterized as oligotrophic.

The Role Of Phospholiphase D In Phospholiphid Transaction During Cotton Seeds Maturation, Muborak Mahmusovna Abdullaeva, Mamura Muhamedovna Mulladganova, Mirzalievna M. Umarova
Turkish Journal of Biology
The role of phospholipase D (EC 3.1.4.4) was studied in the changing of phospholipid content during cotton seed (Gossipium hirsutum 108-G) maturation. To define phospholipase D activity cotton seed homogenates were incubated in a water-methanol environment at 37 °C for various time intervals (15, 30, 60, 120, and 300 min). Enzyme activity was judged from the formation of hydrolysis products - phosphatidic acid and phosphatidylmethanol. The phospholipid content was defined by using thin-layer chromatography with a follow up analysis of phosphorus quantity in phospholipid fractions. It was shown that phospholipase D displayed two functions during cotton seed maturation: transferase and …

Effects Of Some Dna Gyrase Inhibitors On The Survival And Development Of Pimpla Turionellae (Hymenoptera: Ichneumonidae) Larvae Reared On An Artificial Diet, Kemal Büyükgüzel
Effects Of Some Dna Gyrase Inhibitors On The Survival And Development Of Pimpla Turionellae (Hymenoptera: Ichneumonidae) Larvae Reared On An Artificial Diet, Kemal Büyükgüzel
Turkish Journal of Zoology
The effects of novobiocin, nalidixic and oxolinic acids, which are potent antibacterial agents, on the survival and development of the hymenopterous endoparasitoid Pimpla turionellae L. were investigated alone by rearing the larvae aseptically on chemically defined synthetic diets. The percentage of fifth instar larvae was not significantly affected by the diets with different levels of the antibiotics used in the study. A diet containing the lowest level of novobiocin significantly increased the yields of pupae and adults. This level also significantly shortened the developmental time for fifth instar, but had no significant effect on the complete development of the larvae …
