The present study was done to elucidate the effects of vanadium (V) on photosynthetic pigments, membrane damage, antioxidant enzymes, protein, and deoxyribonucleic acid (DNA) integrity in the following chickpea genotypes: C-44 (tolerant) and Balkasar (sensitive). Changes in these parameters were strikingly dependent on levels of V, at 60 and 120 mg V L-1 induced DNA damage in Balkasar only, while photosynthetic pigments and protein were decreased from 15 to 120 mg V L-1 and membrane was also damaged. It was shown that photosynthetic pigments and protein production declined from 15 to 120 mg V L-1 and the membrane was also damaged, while DNA damage was not observed at any level of V stress in C-44. Moreover, the antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) were increased in both genotypes of chickpea against V stress; however, more activities were observed in C-44 than Balkasar. The results suggest that DNA damage in sensitive genotypes can be triggered due to exposure of higher vanadium.

Comparison of benzaldehyde lyase production capacity in recombinant Escherichia coli and recombinant Bacillus species Kaya, Hande; Çalık, Pınar; Department of Chemical Engineering (2006) In this study, the benzaldehyde lyase (BAL, EC 4.1.2.38) production in E. coli BL21 (DE3) pLySs as intracellular and in Bacillus species as extracellular were investigated, and comparison of the production capacity of the enzyme in the developed recombinant microorganisms were compared. For this purpose, firstly, PCR amplified bal gene was cloned into pRSETA vector which is under the control of strong T7 promoter and expressed in E. coli BL21 (DE3) pLysS strain. With developed recombinant E. coli BL21 (DE3)...
Comparative analysis of product and by-product distributions in defined and complex media in serine alkaline protease production by recombinant Basillus subtilis Oktar, Ceren; Çalık, Pınar; Department of Chemical Engineering (2003) In this study, firstly the effects of aspartic acid group amino acids -which were reported to be the potential bottleneck in serine alkaline protease (SAP) synthesis- on SAP production were investigated by substituting at a concentration range of 0-15 mM by using recombinant Bacillus subtilis carrying pHV1434::subC gene. All aspartic acid group amino acids except threonine inhibited SAP activity when CAA= 2.5 mM. The highest SAP activities with asparagine, aspartic acid, lysine, threonine, isoleucine and me...
Modelling of long-term photoresponse of bacteriorhodopsin immobilized on cellulose acetate membranes Sediroglu, V; Aydemir, A; Gündüz, Ufuk; Yucel, M; Turker, L; Eroglu, I (1996-05-01) Purple membrane fragments with its integrated protein bacteriorhodopsin were immobilized on lipid impregnated and lipid free cellulose acetate membranes. Two mathematical models were suggested to simulate the photoresponse curves of these membranes which were obtained by measuring the pH variation independently in each chamber of a specifically designed photoactivity cell for long periods of illumination. The first order model suggested was mainly based on the existence of light phase deprotonation and dark...
Interactive effects of vanadium and phosphorus on their uptake, growth and heat shock proteins in chickpea genotypes under hydroponic conditions Imtiaz, Muhammad; Rizwan, Muhammad Shahid; Mushtaq, Muhammad Adnan; Yousaf, Balal; Ashraf, Muhammad; Ali, Muhammad; Yousuf, Adnan; Rizwan, Muhammad; Din, Mairaj; Dai, Zhihua; Xiong, Shuanglian; Mehmood, Sajid; Tu, Shuxin (2017-02-01) The present study was carried out to examine the interaction of vanadium and phosphorus and changes in heat shock genes to optimize the growth of chickpea genotypes. Two sets of hydroponic experiments were carried out using vanadium and phosphorus with five-level central composite design. Five levels of vanadium (0-1180 mu M) and phosphorus (0-100011 mu M) were used to evaluate their interactive effects. Plants fresh biomass and uptake of vanadium and phosphorus were influenced by vanadium and phosphorus ap...
ANALYSIS OF THE DIELECTROPHORETIC (DEP) SPECTRA OF BIOLOGICAL CELLS Caglayani, Zeynep; Sel, Kaan; Yalcin, Yagmur Demircan; Sukas, Ozlem Sardan; Külah, Haluk (2017-06-22) This study presents an approach for analyzing the dielectrophoretic (DEP) spectra of biological cells without ascertaining their membrane and cytoplasmic properties. DEP spectrum device with reciprocal V-shaped planar-electrodes was utilized to obtain DEP spectra information of cells. Integrating electric field simulations based on a strong theory with the experimental data enables determination of the DEP spectrum at a range of frequencies, for the first in the literature. The proposed method is tested wit...
