Research ArticleOpen accessIn the abstractMicrobial Biodiversity Screening for Metal Accumulators from Mineral Ore Rich Site in Andhra Pradesh, IndiaAditya Kumar Sarkar, Susmita Roy, Ananya Pal et al.Problem statement: Since the site selected for screening was a source of magnetite, the objective of this study was to isolate some groups of magnetotactic bacteria and microbes with potential of metal accumulation. Approach: The culture based approach was used for the study. Pure isolates obtained were characterized on the basis of morphology, biochemical tests, physiology as well as at … …OnLine Journal of Biological Sciences, Vol. 8, Issue 2 · 30 Jun 2008 · 7,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Bacterial Species Isolated from Malaysian Sea Cucumbers with Optimized Secreted Antibacterial ActivityAbd El-Aziem Farouk, Faizal Abd. Hamid Ghouse, B.H. RidzwanIn this study, several Malaysian sea cucumber species that have traditional medicine value were selected and from them, the native bacterial population was isolated. Optimization of growth was designed and all bacterial secretions were tested for antibacterial properties. 30 bacterial types were isolated and 7 types recorded moderate antibacterial activity against K. pneumoniae, S. marscens, P. aeruginosa and E. feacalis. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 8,841 accessesView PDFCite
Research ArticleOpen accessIn the abstractHospital Wastewater Treatment Using an Integrated Anaerobic Aerobic Fixed Film BioreactorA. Rezaee, M. Ansari, A. Khavanin et al.The design and operation of wastewater treatment systems for hospital is a challenge for wastewater engineers. In this study, a pilot-scale system integrated anaerobic-aerobic fixed film reactor for hospital wastewater treatment was constructed and its performance was evaluated. The aim of the study was the elimination of organic compounds and a significant reduction of bacteria. The system had been operated … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Activity of Methyl tert-butyl Ether in Relation to Soil Microorganisms has a Negative Environmental ImpactGholam H.S. BonjarFuel oxygenates are added to gasoline to enhance combustion efficiency of automobiles and reduce air pollution. Methyl tert-butyl ether (MTBE) is the most commonly used oxygenate because of its low cost, high-octane level and ease of blending with gasoline. However, due to its water solubility, high mobility and low biodegradability it leaches in soil subsurface at the speed of groundwater. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,661 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Escherichia coli Isolates from Commercial Layer Hens with SalpingitisMahmood Salehi, Reza GhanbarpourProblem statement: Escherichia coli isolates are the most common bacterial agents of salpingitis in commercial layer hens. The objectives of this study were to determine the phylogenetic groups/subgroups and antibiotic resistance of E. coli isolates from salpingitis cases in commercial layer hens farms in southeast of Iran. Approach: One hundred twenty one E. coli isolates from oviducts of layer hens … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractCirculating Granzymes are associated with Bloodstream Infection and Death in Febrile Medical PatientsAnnelies N. Tacx, Angela M. Wolbink, C. E. Hack, A.B. Johan GroeneveldPlasma levels of granzymes are specific markers for the activation of cytotoxic T lymphocytes and natural killer (NK) cells but the impact of activation of these cells on the course of bacterial infections is not well understood. We prospectively studied the implications of circulating granzyme A and B (GrA, GrB) levels in febrile, medical and hospitalized patients (n=284), during 3 … …American Journal of Infectious Diseases, Vol. 3, Issue 1 · 31 Mar 2007 · 6,736 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBacteria of the Clostridium Genus, Methane and Hydrogen Sulfide in Sulfide Mud of the Taman Peninsula ReservoirsYury Aleksandrovich Fedorov, Gar'kusha Dmitry Nikolayevich, Roman Gennad'yevich TrubnikThe features of the distribution of the concentrations of hydrogen sulfide, methane and the number of sulfite-reducing clostridia in the mud of the Bugazsky, Kiziltashsky and Vityazevsky limans and Chembursky lake were studied, and their physiological and chemical conditions and levels of anthropogenic loading were assessed. The tendency of reduction of the content of the studied reduced gases from the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 Aug 2018 · 7,087 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordScreening of Pseudomonas sp. Isolated from Rhizosphere of Soybean Plant as Plant Growth Promoter and Biocontrol AgentAris Tri Wahyudi, Rika Indri Astuti, GiyantoAbstract: Problem statement: Pseudomonas spesies are one of the rihizobacterial group that have an important role in plant growth promoter and plant health. To prepare them as inoculants, they must have a range of characters as growth promoter such as Indole Acetic Acid (IAA) producers which can promote the growth of plants and solubilize phosphates. In addition, they must also … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 9,882 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPHENOTYPING, VIRULENCE CHARACTERISTICS OF AEROMONAS SPECIES AND THE EFFECTS OF ESSENTIAL PLANT OILS AS ANTIMICROBIAL AGENTS AGAINST PATHOGENIC ISOLATES FROM DIFFERENT SOURCESAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Nihad A.M. El-NasharAeromonas species are increasingly recognized as enteric pathogens. Faecal samples from 20 cow, 45 sheep; 60 goat and 60 camels were examined for the presence of Aeromonas species, which was also sought in the available drinking water (55 well water and 52 drinking chlorinated tap water were also examined). Aeromonas species was isolated more frequently from goats (21.7%) than from … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 18 Jan 2014 · 8,020 accessesView PDFCite
