Research ArticleOpen accessIn the keywordsAntibiotic Resistance and Chromium Reduction Pattern Among ActinomycetesPreeti Jain, Alina Amatullah, Samiul Alam Rajib, Hasan Mahmud RezaActinomycetes, one of the most important groups of microbes, exhibit many interesting activities such as degradation and transformation of organic and metal substrates together with production of antibiotics. With these bioactivities, actinomycetes would play an important role in the webs of the marine environment. The present study was designed to evaluate the antibiotic resistance pattern, antibiotic producing potential and chromium … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 8,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractVisible Derivative Spectroscopic Monitoring of the Old Woman Creek National Estuary During a Historically Dry Year and a Wet YearLorita Nivanthi Mihindukulasooriya, Brenna Shae Mabry, Madison Slocum, Joseph Daniel OrtizVisible derivative spectroscopy was used to interpret the sediment and phytoplankton assemblages within the old woman creek natural estuarine reserve during the summers of 2016 and 2017. A Varimax-rotated Principal Component Analysis (VPCA) of reflectance data collected from four sampling sites in 2016 identified three Varimax-rotated Principal Components (VPCs): Diatom + Illite (2016-VPC 1), Dinoflagellate Algae + Cyanobacteria + Cryptophytes … …American Journal of Environmental Sciences, Vol. 19, Issue 6 · 11 Jul 2024 · 4,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metals Pollution of Owerri and Asuokofi Rivers in Konongo, GhanaWiafe Samuel, Buamah Richard, Essandoh HelenThe effects of polluted water and soil resulting from anthropogenic activities have impacted negatively on the livelihood of both human and animal existence. A thorough study was therefore required to ascertain the extent of pollution caused by the undertakings of these anthropogenic activities particularly within the Asante Akim Central Municipality of Ghana. This study assesses the dispersions and the extent … …American Journal of Environmental Sciences, Vol. 17, Issue 2 · 14 Jun 2021 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study on the Microbial Community Structure of the Sediment of Pi River under the Different pH in WinterCairui Yu, Dongmei Shen, Wanfeng Wang et al.In order to solve the poor self-purification ability of low temperature water in winter, the microbial community structure in the sediment of Pi River water (located in West Anhui) was investigated experimentally in this study. Firstly, the sediment was sampled in the lower reaches of Pi River and prepared with the different pH (5.0, 5.5, 7.0 and 8.5); secondly, the … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 15 Mar 2021 · 6,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Geothermal Energy Potential of Ruwan Zafi, Adamawa State and Environs, Northeastern Nigeria, using High Resolution Airborne Magnetic DataIbe Stephen Onyejiuwaka, Uche Kelvin IdumaThe aeromagnetic dataset over Ruwan Zafi, Adamawa State and environs, Northeastern Nigeria, was interpreted in this study, in order to map out places with the potentials for application of geothermal energy for electricity generation and geothermal direct heating. The analysis of the spectral of the magnetic dataset delineated the range of the sediment thickness as 4273.58 and 8693.32 m and … …Current Research in Geoscience, Vol. 10, Issue 1 · 4 Dec 2020 · 12,352 accessesView PDFCite
Research ArticleOpen accessIn the abstractMapping, Characterization and Dispersion of Metallic Pollutants within a Catchment of Illegal Gold Mining Activities in GhanaWiafe Samuel, Richard Buamah, Helen Essandoh, Lawrence DarkwahThe illegal gold mining activities prevalent in most part of Ghana have caused substantial havoc to the environment especially water bodies which serve as sources of water for domestic, industrial and agricultural purposes. The Ghana Water Company Limited (GWCL) recently shut down their water treatment plant due to the extreme pollution and high cost of treatment.
