synthesis and characterization of some new cyclometalated organoplatinum(ii) complexes containing phosphite ligand
در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...
Bioenergetics Studies of the Cyanobacterium Anabaena variabilis
A cell-free system exhibiting both photophosphorylation (P /2e = 1) and oxidative phosphoryla tion (P/O up to 0 .8 ) is described for the cyanobacterium Anabaena variabilis. NADH and N A D PH were found to be equally effective as electron donors for oxidative phosphorylation. Low concentrations of U H D B T , an inhibitor of the cytochrome blc complex of mitochondria and chloroplasts. were fou...
متن کاملCharacterization of factors influencing the growth of Anabaena variabilis in a bubble column reactor.
The combined effect of superficial gas velocity, pH, initial phosphate concentration, and light intensity on cell growth was investigated for the mass production of cyanobacterial cells. The light intensity was manipulated to maintain a specific irradiation rate (q(i)) at a constant level for high cell density culture. The optimum condition for the batch culture was achieved at a superficial ga...
متن کاملCharacterization of genes for a second Mo-dependent nitrogenase in the cyanobacterium Anabaena variabilis.
Anabaena variabilis ATCC 29413 is a filamentous heterocystous cyanobacterium that fixes nitrogen under a variety of environmental conditions. Under aerobic growth conditions, nitrogen fixation depends upon differentiation of heterocysts and expression of either a Mo-dependent nitrogenase or a V-dependent nitrogenase in those specialized cells. Under anaerobic conditions, a second Mo-dependent n...
متن کاملIsolation and characterization of the VnfEN genes of the cyanobacterium Anabaena variabilis.
The filamentous cyanobacterium Anabaena variabilis fixes nitrogen in the presence of vanadium (V) and in the absence of molybdenum (Mo), using a V-dependent nitrogenase (V-nitrogenase) encoded by the vnfDGK genes. Downstream from these genes are two genes that are similar to the vnfEN genes of Azotobacter vinelandii. Like the vnfDGK genes, the vnfEN genes were transcribed in the absence of Mo, ...
