Research ArticleOpen accessIn the abstractISOLATION AND CHARACTERIZATION OF BIFENTHRIN CATABOLIZING BACTERIAL STRAIN BACILLUS CIBI FROM SOIL FOR PYRETHROIDS BIODEGRADATIONPreeti Pandey, Geetika Pant, G. SibiPyrethroids are commonly used in most parts of the world and are reported to have potential health risks. Bifenthrin, a third generation pyrethroid used as insecticide has caused potential effect on aquatic life and human health. Bioremediation is a practical approach to reduce pesticide in the environment and reports of microbial degradation of bifenthrin are meagre. This study was aimed … …OnLine Journal of Biological Sciences, Vol. 14, Issue 3 · 15 Sep 2014 · 7,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION OF BIOMASS, INDIAN JUJUBA SEED (IJS) FOR REMOVAL OF CONGO REDL. Sivaramakrishna, M. Sivasankar Reddy, M. Jagadeesh et al.The present investigation deals with the removal of Congo Red (CR) from aqueous solution by using Indian Jujuba Seed (IJS) as low-cost biosorbent. The effect of pH and size experimental parameters has been investigated using a Batch adsorption technique. Adsorption data were modeled using Langmuir and Freundlich adsorption isotherms. Adsorption kinetics was verified by pseudo-first order, pseudo-second order and intraparticle … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 30 Jun 2014 · 7,181 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 abstractInfluence of Process Conditions on Measles Virus StabilityK. Weiss, D. Salzig, J. Gerstenberger et al.Recombinant measles viruses are currently tested in clinical trials as oncolytic agent to be applied in cancer therapy. Contrary to their use as vaccine where 103 infectious virus particles per dose are needed, for cancer therapy 109 virus particles should be provided per dose. This leads to other challenges for the production process when compared to vaccine production. This study … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 9,949 accessesView PDFCite
Research ArticleOpen accessIn the abstractCassava Chip Drying by Using a Small-Scale Hot-Air Microwave OvenPatomsok WilaiponCharacteristics of cassava microwave hot-air drying were investigated in a 2-planes microwave hot-air dryer. The drying experiments were carried out at two levels of sample surface temperature set-points viz. 70 and 80°C respectively. Cassava (Rayong-9) with 2.5 kg weight and 61% moisture content on wet basis was dried in the dryer for about 5-5.3 h. It was found that the … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 6 Jun 2013 · 7,569 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochemical Studies of Lipase from Germinating Oil Seeds (Glycine max)P. P. Gadge, S. D. Madhikar, J. N. Yewle et al.Problem statement: Lipase is one of the important enzymes in food, pharmaceutical, detergent and biofuels industries. Search for the lipase with distinct features, possibly from germinating seeds, is of interest for industrial applications. Approach: The lipase produced by soybean oil seeds was partially purified and characterized in terms of the optimal pH and temperature for activity as well as substrate … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 19 Jan 2012 · 9,703 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Hydrogen/Oxygen Release Compounds for the Remediation of VOCsS. Fiore, M.C. ZanettiProblem statement: Volatile Organic Compounds (VOCs) were widespread in groundwater of industrialized areas and in situ remediation intervents characterized by a high environmental compatibility were of main interest. The scope of this study was the evaluation of the potential of two innovative reagents (HRC and ORC from Regenesis) for the remediation of Volatile Organic Compounds (VOCs). The reagents respectively perform … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 4 Nov 2011 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelisation of Nitrification under Inhibited Environment by Moving Bed Bio-Film Reactor TechniquePham Thi Hong Duc, Le Van Cat, Jean-Luc VaselProblem statement: Nitrification by Moving Bed Biofilm Reactor (MBBR) involves physical, chemical and biological processes to remove toxic ammonia for aquaculture that are governed by a variety of parameters, like substrate and dissolved oxygen concentrations, organic matters, temperature, pH, alkalinity and turbulence level, which impact negatively or positively on nitrification kinetics.
