Two methods described in this paper use respirometric monitoring of the accumulated oxygen uptake rate, following the addition of bleachery effluents to a reactor containing Penicillium camemberti and detection of inorganic chloride removal by a chloride electrode for electron acceptor identification. In the case of respirometric studies, adsorbable organic halogens (AOX) removal was retarded at high acetate concentrations and the metabolism shifted towards aerobic respiration. Contrary to this, aerobic respiration was suppressed at low acetate concentrations and the removal of AOX was enhanced. Inorganic chloride removal detected with a chloride electrode verified these findings too. Cl- ion production paralleling AOX removal supports the hypothesis that organic chlorine acts as electron acceptor for this fungus.

Development of novel asymmetric catalysts for various transformations and investigation of a rearrangement reaciıon Yazıcıoğlu, Emre Yusuf; Tanyeli, Cihangir; Department of Chemistry (2010) A new class of pyridine and sulfur containing chiral compounds are synthesized. Camphor sulfonyl chloride is chosen as a valuable chiral starting compound. In our synthetic strategy, sulfonylchloride moiety is first reduced to corresponding thiol compound by using triphenylphosphine and then the resultant thiol will be converted to various alkyl, aryl substituted derivatives. The second part of our strategy includes the pyridine ring construction on the carbonyl side of camphor with the formation of β-hydro...
Purification and characterization of an intracellular chymotrypsin-like serine protease from Thermoplasma volcanium Kocabıyık, Semra (2006-01-01) An intracellular serine protease produced by Thermoplasma (Tp.) voleanium was purified using a combination of ammonium sulfate fractionation, ion exchange, and et-casein agarose affinity chromatography. This enzyme exhibited the highest activity and stability at pH 7.0, and at 50 degrees C. The purifed enzyme hydrolyzed synthetic peptides preferentially at the carboxy terminus of phenylalanine or leucine and was almost completely inhibited by PMSF, TPCK, and chymostatin, similarly to a chymotrypsin-like ser...
Synthesis of 1,2,3,5- tetrasubstituted pyrrole derivatives via 5-exo-dig type cyclization and stereoselective functionalisation of ferrocene derivatives Kayalar, Metin; Demir, Ayhan Sıtkı; Department of Chemistry (2005) A convenient and new method for the synthesis of 1,2,3,5-tetrasubstituted pyrrole derivatives starting from 1,3,-dicarbonyl compounds through acid catalyzed cyclization reaction is described. Alkylation of 1,3-dicarbonyl compound with propargyl bromide followed by one step cyclization with the introduction of primary amines in the presence of catalytic amount of triflouroacetic acid (TFA) affords the corresponding pyrrole derivatives in high yields. The investigations on the studies of developing a new meth...
Addition of 1,3-dicarbonyl compounds to the cycloheptatriene derivatives Südemen, M. Burak; Balcı, Metin; Department of Chemistry (2009) The one electron oxidant Mn(OAc)3 has been used for years for the oxidative addition of 1,3-dicarbonyls to alkenes to give dihydrofuranes. Since cycloheptatriene is in equilibrium with its valance isomer norcaradiene, it will be interesting to study the reaction of CHT derivatives with Mn(OAc)3 in the presence of 1,3-dicarbonyls. In our research, we have observed that unsubstituted cycloheptatriene gave CHT based products. However, when electron withdrawing -CN group was attached to C-7 position of CHT we o...
Identification of small-molecule urea derivatives as novel NAMPT inhibitors via pharmacophore-based virtual screening Ozgencil, Fikriye; EREN, GÖKÇEN; ÖZKAN, YEŞİM; GÜNTEKİN ERGÜN, SEZEN; Atalay, Rengül (Elsevier BV, 2020-01-01) Nicotinamide phosphoribosyltransferase (NAMPT) catalyzes the condensation of nicotinamide (NAM) with 5-phosphoribosyl-1-prophosphate (PRPP) to yield nicotinamide mononucleotide (NMN), a rate limiting enzyme in a mammalian salvage pathway of nicotinamide adenine dinucleotide (NAD(+)) synthesis. Recently, intracellular NAD(+) has received substantial attention due to the recent discovery that several enzymes including poly(ADPribose) polymerases (PARPs), mono(ADP-ribose) transferases (ARTs), and sirtuins (SIR...
