Isolation and spectral characterization of phycobiliproteins.

Optimization,Purification and characterization of Phycocyanin from Spirulina platensis

A method for stably purifying a functional dye, phycocyanin from Spirulina platensis was developed by freezing and thawing method. Among various buffers used for phycocyanin yield efficiency sodium phosphate buffer (pH 7 and 0.1 M) was found to be most suitable for highest yield. During comparison of various buffers, sodium phosphate buffer was found as best buffer with 146 ±0.265 mg/g phycobil...

The Effect of Different Light Intensities on Physiological and Biochemical Responses in Cyanobacterium Schizothrix vaginata under Naphtalene Treatment

Petroleum hydrocarbons pollution is one of the problems in the environment due to petroleum industry processes. Biological methods are novel routs to defend against them. In this research, the effect of light intensities on biodegradation of naphthalene and the physiological responses of cyanobacterium Schizothrix vaginata is investigated. In this order, studied cyanobacterium transfered to liq...

Synthesis, Spectral Characterization and DFT Calculations of New Co(II) Complexes Derived from Benzimidazoles

The synthesis, characterization and quantum-chemical investigations of two new Co(II) complexesderived from fluorescent benzimidazoles have been reported. Two new fluorescentheterocyclic ligands were synthesized from the reduction of imidazo[4',5':3,4]benzo[1,2-c]isoxazole derivatives, and characterized by elemental analyses, IR, mass, and NMR spectra. Coordination of the bidentate ligands ...

Synthesis and spectral characterization of naphthyldihydrazones derived from some 1,3- dicarbonyl compounds and their Ni(II), Cu(II) and Zn(II) complexes

The coupling of tetrazotised 1,8-diaminonaphthalene with 1,3-dicarbonyl compounds [acetylacetone,methylacetoacetate and acetoacetanilide] yielded a new series of tetradentate ligand systems. Analytical, IR,1H NMR and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bondeddihydrazone form. Dibasic tetradentate N2O2 coordination of these compounds in their [ML...
