Research ArticleOpen accessIn the abstractSynthesis and Biological Evaluation of 6-Hydroxy-4-Methyl-5,7-(Bis-p-ChlorophenylAzo) CoumarinDalal M. Ibrahim, Juliana Jumal, Farah Wahida Harun6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarinhas been synthesized and characterizedby CHN elemental analysis, FTIR, 1H-NMR-spectroscopy andmass-spectral data. Cytotoxic screening by MTT assay was carried out on the compoundagainst breast cancer cells. The overall results from preliminary screeningprogram revealed that the cell proliferation was highly inhibited by 6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarin with the value of 2.81%, at concentration of 30 µg mL-1 comparedwith the untreated control cells and also … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 21 Dec 2015 · 7,670 accessesView PDFCite

Crude extracts exhibit high … …Current Research in Nanotechnology, Vol. 6, Issue 2 · 5 Nov 2015 · 15,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Cultural Conditions for Production of Exopolysaccaride by Halomonas marina HMA 103 under Batch-CultureArundhati Pal, Amrita Biswas, Sriya Chatterjee, A. K. PaulA moderately halophilic bacterium, Halomonas marina HMA 103 (MTCC 8968) accumulating intracellular polyesters also produced significant amount of exopolysaccharides (EPS) under batch-culture. Production of EPS by the bacterium was more or less parallel with the growth in modified basal synthetic medium. During growth, it produced 0.46 g/L of EPS after 50 h of incubation and was accompanied by the complete … …Current Research in Microbiology, Vol. 6, Issue 2 · 27 Jul 2015 · 7,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractBIOTRANSFORMATION OF TEXTILE DYES: A BIOREMEDIAL ASPECT OF MARINE ENVIRONMENTR. S. Shertate, Prakash ThoratPresence of huge amount of salts in the wastewater of textile dyeing industry is one of the major limiting factors in the development of an effective biotreatment system for the removal of dyes from textile effluents. Large number of textile industries are located on the coastal areas due to ease of transport to the various places in world and help … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 7,383 accessesView PDFCite
Research ArticleOpen accessIn the abstractSYNTHESIS AND CHARACTERIZATIONOF ORGANIC FUNCTIONALIZED MESOPOROUS SILICA AND EVALUATE THEIR ADSORPTIVE BEHAVIOR FOR REMOVAL OF METHYLENE BLUE FROM AQUEOUS SOLUTIONSameer H. Kareem, Inaam H. Ali, M. G. JalhoomThree Mesoporous Silica (MPS) with different functional groups were prepared by one-step synthesis based on the simultaneous hydrolysis and condensation of tetraethoxy silane with organo-silane in the presence of template surfactant Polydimethylsiloxane-Polyethyleneoxide (PDMS-PEO). The prepared materials were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and nitrogen adsorption-desorption experiments. The results indicate that the preparation of methyl and … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 28 Feb 2014 · 7,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption from Aqueous Solution Onto Natural and Acid Activated BentoniteLaila Al-Khatib, Feras Fraige, Mohammad Al-Hwaiti, Omar Al-KhashmanDyes have long been used in dyeing, paper and pulp, textiles, plastics, leather, paint, cosmetics and food industries. Nowadays, more than 100,000 commercial dyes are available with a total production of 700,000 tones manufactured all over the world annually. About 10-15% of dyes are being disposed off as a waste into the environment after dyeing process. This poses certain hazards … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 28 Aug 2012 · 8,417 accessesView PDFCite
