Research ArticleOpen accessIn the abstractLocalization of the Dissimilatory Arsenate Reductase in Sulfurospirillum Barnesii Strain SeS-3Eman AfkarProblem statement: Sulfurospirillim barnesii strain SeS-3 is one of the recently known bacterial isolates that can obtain energy to support growth by respiring the toxic oxyanions of arsenic and selenium under anaerobic conditions. Approach: The ultimate goal of this investigation is to localize the active sites for the reduction of arsenate arsenite as well as selenate selenite in S. barnesii … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Mar 2012 · 7,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecolorization of Mordant Orange-1 by Marinobacter algicola MO-17R. S. Shertate, Prakash ThoratProblem statement: The textile industries use different types of dyes in their processing units which are liberated in natural marine water bodies. This release of dyes in turn affect the marine flora and fauna very adversely. Approach: The release of textile dyes into the environment is a matter of concern due to the toxicity, mutagenicity, carcinogenicity and xenobiotic nature. Hence, … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 25 Feb 2012 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Affecting the Geometry of Silver Nanoparticles Synthesis in Chrysosporium Tropicum and Fusarium OxysporumNamita Soni, Soam PrakashProblem statement: Biosynthesis of nanoparticles using fungal cells is a novel approach to develop biotechnological possess such as bioleaching and bioremediation. In the present study, an effort was made to investigate the effect of physio-chemical parameters on the silver nanoparticle formation with the fungus Chrysosporium tropicum Carmichael and Fusarium oxysporum Schltdl. Approach: The possibilities to manipulating the geometry of silver … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 20 Jan 2012 · 19,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosurfactan Production by Bacillus sp. Isolated from Petroleum Contaminated Soils of Sirri IslandM. Ghayyomi Jazeh, F. Forghani, Deog-Hwan OhProblem statement: Biosurfactants are active surface components produced by some bacteria and fungi. These molecules reduce surface and interfacial tension in aqueous solutions and hydrocarbon mixtures. The most important application of biosurfactants is in oil industry to enhance oil quality and facilitate oil extraction. The aim of this study was to isolate biosurfactant producing bacteria and optimize the conditions like … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 13 Jan 2012 · 8,552 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 · 8,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrocarbon Biodegrading Potentials of a Proteus vulgaris Strain Isolated from Fish SamplesPatience O. Olajide, L. B. OgbeifunA Proteus vulgaris bacterium SR-1 was isolated from a freshly killed fish sample collected close to the point of crude oil spill in the Niger Delta region, Nigeria. Problem statement: The application of native bacterial species in bioremediation processes has long been desired, because they would be cost effective and efficient in terms of acclimation time. The ability to isolate … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 8,277 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaccumulation of Arsenic by FungiAdemola O. AdeyemiProblem statement: Arsenic is a known toxic element and its presence and toxicity in nature is a worldwide environmental problem. The use of microorganisms in bioremediation is a potential method to reduce as concentration in contaminated areas. Approach: In order to explore the possible bioremediation of this element, three filamentous fungi-Aspergillus niger, Serpula himantioides and Trametes versicolor were investigated for … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradative Plasmid and Heavy Metal Resistance Plasmid Naturally Coexist in Phenol and Cyanide Assimilating BacteriaBahig El. Deeb, Abdullah D. AltalhiProblem statement: Heavy metals are known to be powerful inhibitors of xenobiotics biodegradation activities. Alleviation the inhibitory effect of these metals on the phenol biodegradation activities in presence of heavy metals resistant plasmid was investigated. Approach: Combination of genetic systems of degradation of xenobiotic compound and heavy metal resistance was one of the approaches to the creation of polyfunctional strains … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 11,984 accessesView PDFCite
