Research ArticleOpen accessIn the abstractEffect of Dose-Response of Zinc and Manganese on Siderophores ProductionMehri Ines, Khessairi Amel, Turki Yousra et al.Problem statement: This study was conducted to find and determine whether the siderophores of the four environmental Pseudomonas spp. isolates possess a sequestering activity towards essential transition metals (Zn and Mn) other than iron. Approach: Four fluorescent Pseudomonads isolated from various environments, were characterized analytically (Isoelectric focusing), biologically (pyoverdine-mediated uptake) and genetically (16S rDNA sequencing). By means of spectrophotometric measurements, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 10 Mar 2012 · 7,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Shrimp Farm Effluent on Water Quality in Coastal Areas of the World Heritage-Listed Ha Long BayThuyet D. Bui, Jim Luong-Van, Chris M. AustinProblem statement: Shrimp farming has rapidly developed in coastal areas of the World Heritage-listed Ha Long Bay since the last decade. Effluent discharged from shrimp farms with high levels of nutrient waste may cause eutrophication in receiving waterways. Therefore, assessing water quality at tidal creeks receiving shrimp farm effluent in coastal areas of Ha Long Bay supports environmental protection and … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 3 Mar 2012 · 11,289 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiofilter Treating Ammonia Gas Using Agricultural Residues MediaThaniya Kaosol, Nutthawut PongpatProblem statement: Agricultural residues such as manure and sugarcane bagasse are wastes from agro-industry which has low value and requires some sustainable waste management method. In this research, a mixture of manure fertilizer and sugarcane bagasse is used as a biofilter media for an ammonia gas removal application. The aim of this research is to study the ammonia gas removal … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 21 Feb 2012 · 7,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Innovative Farm Scale Biogas/Composting Facility for a Sustainable Medium Size Dairy FarmA.E. Ghaly, M. Al HattabApproach: The amount of energy related costs as a portion of the total farm operating cost can be as high as 29% and the continuing increase of the real cost of energy related farm input has been one of the major factors impacting the cost of agricultural production. However, agricultural has the potential of replacing some of the purchased energy … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Jan 2012 · 9,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Transport Properties of Tyre Fiber Modified ConcreteG. Senthil Kumaran, M. Lakshmipathy, Nurdin MushuleProblem statement: Nowadays, the use of waste tyre in concrete has become technically feasible and the tyre mixed concrete is light weight and called as rubberized concrete. Still the research is going on to explore basic engineering properties such as transport properties viz, acid absorption test, water absorption tests, impact resistance, modulus of elasticity, dynamic modulus and so on. In … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 30 Sep 2011 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodegradation of Phenolic Compounds in Creosote Treated Wood Waste by a Composting Microbial Culture Augmented with the Fungus Thermoascus aurantiacusAbdel E. Ghaly, Bopeng Zhang, Deepika DaveProblem statement: Creosote is used as a wood preservative and water proof agent in railway sleepers, utility poles, buildings foundations and fences and garden furniture. It is a mixture of over 300 hydrocarbons which include 75% polycyclic aromatic hydrocarbons, 2-17% phenolic compounds and 10-18% heterocyclic organic compounds. Exposure to creosote may result in several health problems including damage to kidney, … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 26 Aug 2011 · 9,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Consortia from Taptapani Hot Water Springs for Mining Effluent TreatmentPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriProblem statement: Soluble sulfate load in effluent is a crucial problem from mining industries. The study involved isolation of efficient Sulfate Reducing Bacterial (SRB) consortium from hot water spring for bioremediatrion of sulfate contaminated waste water. Approach: The enriched bacterial consortium was isolated in medium DSMZ 16695. The sulfate reduction efficiency was measured by turbidometric method. The Km and Rmax … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of the Water Quality Index of Otamiri and Oramiriukwa RiversA.N. Amadi, P.I. Olasehinde, E.A. Okosun, J. YisaProblem statement: The impact of anthropogenic activities on Otamiri and Oramiriukwa Rivers as a result of the increasing rate of urbanization in Owerri, Nigeria is of a great concern due to the fact that water from these rivers is the source of water distributed for public use. These rivers are of particular importance in the study of surface water pollution … …Physics International, Vol. 1, Issue 2 · 31 Dec 2010 · 8,552 accessesView PDFCite
Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaugmentative Approaches for Dairy Wastewater TreatmentIrina Schneider, Yana TopalovaProblem statement: The achievement of a good ecological status of water receivers after discharge of waste or partially treated water from dairy industry requires harmonic interaction between water treatment technology and self-purification processes. Approach: The present research included two modules. First: an anaerobic treatment process for dairy wastewater in broadly spread sequencing batch bioreactor with fixed biomass was studied. As … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 8,897 accessesView PDFCite
