Research ArticleOpen accessIn the keywordsMicrotox Toxicity Assay for the Sediment Quality Assessment of Ganga RiverK.R. Beg, S. AliThe objective of this study was to determine the sediment quality assessment of Ganga River at Kanpur city where effluents from tannery industries are discharged. Sediment samples from control, upstream and downstream area were collected and analyzed for bacterial toxicity bioassay along with a reference sediment (LGC6137). The control samples collected from the point of origin of Ganga River at … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,614 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction, Partial Identification and Bioactivities of Total Flavonoids from Carex meyeriana KunthHongbiao Wang, Penghui Wang, Xiudong Yang et al.To date, knowledge associated with extraction, chemical constituents and bioactivities of Total Flavonoids from Carex meyeriana Kunth (TFCMK) that remains unclear. Therefore, this paper was designed to optimize the ethanol reflux extraction method by response surface methodology and determine the chemical constituents by Liquid Phase-Mass Spectrometry (HPLC-MS); additionally, the bioactivities including antioxidant, antibacterial and hemolysis test were also explored. The … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 7 Aug 2019 · 7,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractProducts of Solid-Phase Probiotic Bacilli Fermentation Increase Food Conversion Efficiency and Stimulate Chicken GrowthMazanko Maria S., Aleksandr I. Klimenko, Ivan F. Gorlov et al.Poultry farming is one of the major directions in agriculture. Agricultural poultry has high growth speed, productivity and is resistant to the industrial environment. Our group carried out a study of probiotic preparations of Bacillus subtilis KATMIRA1933 and Bacillus amyloliquefaciens B-1895 strains. These preparations were made by solid-phase fermentation and tested for dynamical germination of rearing flock (Highsex brown). The … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 4 · 4 Dec 2018 · 9,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractRheological Characterization of Sludge Coming from a Wastewater Treatment PlantDaniel Novarino, Ezio Santagata, Davide Dalmazzo, Mariachiara ZanettiProblem statement: The aim of this study was that of studying the rheology of sewage sludge using two different rheological test protocols taken from literature and comparing them in order to evaluate which useful information are given from every protocol. Approach: Two different protocols have been used taking particularly into account the problems connected to sludge heterogeneous composition and to … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractSorption of Phenols: Influence of Groundwater pH and of Soil Organic Carbon ContentSilvia Fiore, Maria Chiara ZanettiProblem statement: Physical and chemical properties of soil, groundwater and pollutants deeply influenced the type and the strength of sorption phenomena involving hydrophobic organic contaminants: Soil fraction of organic carbon (foc) and cation exchange capacity, groundwater pH and pollutants hydrophobicity were with undoubtedly the predominant issues. Approach: In this study an experimental study of the sorption of phenol and 2-nitrophenol … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption Study of Several Hydrophobic Organic Contaminants on an Aquifer MaterialBarbara Ruffino, Mariachiara ZanettiProblem statement: Aim of the present research was to determine coefficient of partition KD between soil and groundwater for five hydrophobic organic pollutants (benzene, chlorobenzene, trichloroethylene-TCE, perchloroethylene-PCE and toluene) in an Italian aquifer material characterized by a low organic carbon content (fOC = 0.00262) by means of laboratory batch tests. Initial aqueous concentrations (quite different among the five compounds) were … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction of Genomic DNA Using Magnetic Nanoparticles (Fe3O4) as a Solid-Phase SupportZ. M. Saiyed, C. N. RamchandMagnetic separation technology, using magnetic particles, is quick and easy method for sensitive and reliable captures of specific proteins, genetic material and other biomolecules. The current paper describes a universal genomic DNA extraction method optimized in our laboratory using magnetic nanoparticles as a solid phase adsorbent.
