A paper-based biosensor was developed for the detection of the degradation products of organophosphorus pesticides. The biosensor quantifies acetylcholine esterase inhibitors in a fast, disposable, cheap, and accurate format. We specifically focused on the use of sugar or protein stabilizer to achieve a biosensor with long shelf-life. The new biosensor detected malathion with a detection limit of 2.5 ppm in 5 min incubation time. The operational stability was confirmed by testing 60 days storage at 4 degrees C when glucose was used as stabilizer.

A fast switching, low band gap, p- and n-dopable, donor-acceptor type polymer Günbaş, Emrullah Görkem; Akhmedov, Idris Mecidoglu; Tanyeli, Cihangir; Önal, Ahmet Muhtar; Toppare, Levent Kamil (Elsevier BV, 2008-04-01) A new electrochromic polymer, poly(2,3-diplienyl-5,7-bis(3,4-ethylenedioxy-2-thienyl)thieno[3,4-b]pyrazine) (PGS) is electrochemically synthesized and its electrochromic properties are reported. PGS showed well defined electrochemical characteristics with a relatively low oxidation potential of 0. 18 V vs Ag/Ag+. Polymer also exhibited a definite redox couple at applied cathodic potentials, indicating n-doping characteristic of the polymer. Spectroelectrochemistry and previously unattempted technique, ESR d...
Utilization of pretreated molasses for serine alkaline protease production with recombinant Bacillus species Calik, G; Pehlivan, N; Kalender, N; Ozdamar, TH; Çalık, Pınar (Informa UK Limited, 2003-05-01) Recombinant Bacillus amyloliquefaciens, Bacillus cereus, Bacillus subtilis , and Bacillus licheniformis were used for the production of serine alkaline protease (SAP) utilizing chemically and/or physically pretreated molasses. The highest enzyme activity was obtained with r- Bacillus subtilis , with the complex medium involving physically treated molasses having 20 kg m(-3) initial sucrose concentration in small-scale, agitation- and heating rate-controlled bioreactors at t=63 h. Effects of oxygen transfer ...
Phenol biosensor based on electrochemically controlled integration of tyrosinase in a redox polymer Yildiz, Huseyin Bekir; Castillo, Jaime; Guschin, Dmitrii A.; Toppare, Levent Kamil; Schuhmann, Wolfgang (Springer Science and Business Media LLC, 2007-06-01) An amperometric biosensor for the detection of phenolic compounds was developed based on the immobilization of tyrosinase within an Os-complex functionalized electrodeposition polymer. Integration of tyrosinase within the redox polymer assures efficient catechol recycling between the enzyme and the polymer bound redox sites. The non-manual immobilization procedure improves the reproducibility of fabrication process, greatly reduces the desorption of the enzyme from the immobilization layer, and, most import...
Development of a 635nm-Laser Diode Spectrometer for Continuous Monitoring of Amino Nitrogen in the Beet Sugar Industry ÜLGEN, Ahmet; Gökmen, Ali; ŞAHİN, Uğur; Herdem, Huelya; Cengiz, Hasan I. (Informa UK Limited, 2009-01-01) The quality of sugar beet is affected by harmful nitrogen compounds. Although nitrogen is one of the essential elements for plants, introduction of excess nitrogen as fertilizer to the soil increases the nitrogen containing compounds in beet which deteriorates the quality of sugar production. Hence, the concentration of soluble nitrogen in beets was monitored as a routine process in the sugar industry. In this work, a low cost, but very long life time laser diode spectrometer, was developed for continuous m...
Cytochrome P4501A and associated mixed-function oxidase induction in fish as a biomarker for toxic carcinogenic pollutants in the aquatic environment Arinc, E; Sen, A; Bozcaarmutlu, A (Walter de Gruyter GmbH, 2000-06-01) Polycyclic aromatic hydrocarbons (PAHs), dioxins, dibenzofurans, and polychlorinated biphenyls (PCBs) present in polluted environment induce cytochrome P4501A (CYP1A) isozyme in fish, which in turn results in a marked increased production of carcinogenic metabolites from PAHs. The induction of hepatic CYP1A in fish by certain classes of chemicals has been suggested as an early warning system, a "most sensitive biological response" for assessing environmental contamination conditions. This has implications f...
