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 · 9,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysicochemical and Microbial Caracteristics Performency in Wastewater Treated Under Aerobic ReactorAsma Ben Rajeb, Hamadi Kallali, Neila Saidi et al.Problem statement: The current work study the efficiency of biological wastewater treatment by an aerobic reactor which could be used in small agglomerations. RBC reduced physicochemical and microbiological load of wastewater but values remain above Tunisian standard. Approach: Experiments were conducted on a sand filled PVC column fed with wastewater treated by Rotating Biological Contactor (RBC) at a pulsed rhythm … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractCondoms-As Sources of Extracellular Enzyme Producing MicrobesMadhusmita Mishra, Poulomi Nandy, Sarvani Debsarma et al.Problem statement: Condoms are widely used birth control measures which are made of natural latex or synthetic materials like polyurethane or polyisoprene as matrix with lubricants added to make them ready to use commodities. Absence of sterilization method along with presence of lubricant like petroleum jelly (that are applied on the outer surface), prompted the investigators to look for microbes … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractSepticemia: The Principal Killer of Burns PatientsB. R. Sharma, Virendar Pal Singh, Sumedha Bangar, Neha GuptaBurn injury is a major problem in many areas of the world and it has been estimated that 75% of all deaths following burns are related to infection. Burns impair the skin’s normal barrier function thus allowing microbial colonization of the burn wounds and even with the use of topical antimicrobial agents, contamination is almost unavoidable. It is therefore essential … …American Journal of Infectious Diseases, Vol. 1, Issue 3 · 30 Sep 2010 · 7,022 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Soluble Sulfate Reduction by Bacterial Consortia from Varied Regions of IndiaPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriSoluble sulfate contamination in water is observed due to various industrial activities. Chemical means of reduction are available yet the biological approach is the preferred one. Problem statement: The problem addressed in this study was the isolation of efficient sulfate reducing bacterial consortia for bioremediation of soluble sulfate from mining effluent. Approach: The culture based method using the DSMZ specific … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,338 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Response to the Application of Amendments in a Contaminated Soil with Trace ElementsA. Branzini, M. S. Zubillaga, M. M. ZubillagaProblem Statement: The anthropogenic activities can cause adverse effects in soils, increasing in some situations trace elements contents, impacting negatively both the microbial biomass and activity. Among the practices used for the recovery of soil quality we can find the application of organic amendments or the product of their composting. These can adsorb trace elements decreasing their availability and increasing … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent Approaches for the Prevention of Surgical Site InfectionsSander Florman, Ronald Lee NicholsSurgical site infections (SSIs) are the most common type of nosocomial infection among surgical patients and are commonly caused by the patients’ own microbial flora. The prevalence of SSI is a major concern because of the associated increase in the incidence of morbidity and mortality, length of hospitalization and cost of care for postoperative patients. Key factors that determine whether … …American Journal of Infectious Diseases, Vol. 3, Issue 1 · 31 Mar 2007 · 7,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractControl of Phenolic Compound Secretion and Effect of Growth Regulators for Organ Formation from Musa spp. cv. Kanthali Floral Bud ExplantsSoubir Titov, Salil Kumar Bhowmik, Ajoy Mandal et al.The study was undertaken to examine banana cv. Kanthali floral bud apex as an alternative source material for in vitro propagation because huge number of explants die due to microbial contamination in case of shoot tip explants. Contamination free cultures were established by treating the floral bud explants with 0.1% HgCl2 for 6 min. This study found that inflorescence tissues … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 7,742 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMechanism of Garden Aquatic Plants in the Remediation of Heavy Metal-Contaminated SoilChen Chen, Guangwu LiuHeavy metals such as cadmium, lead, and mercury are resistant to microbial degradation in soil and persist for extended periods. They can bioaccumulate through the food chain, ultimately impacting human health. This study demonstrates that a combined restoration approach involving soil enhancement and garden aquatic plants, specifically through the application of ferrous sulfate, results in increased dry weight and plant … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 20 Apr 2026 · 1,497 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDiversity and Resistance of Bacteria Isolated from a Neonatal Intensive Care Unit (NICU) Surfaces and the Hands of Nurses in Jeddah-Saudi ArabiaRoqaiah M. Al-Jabri, Ahmed M. Al-Hejin, Rukaia Gashgari et al.Healthcare-Associated Infections (HAIs) are a serious problem for neonates when admitted to NICUs. The healthcare environment and healthcare workers' hands may be a source of transmission. Therefore, there is a need to find microbial sources and identify the contaminants to improve disinfection protocols to reduce HAIs. Out of the 169 samples collected on nutrient agar media from NICUs of a … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 5 Aug 2022 · 5,828 accessesView PDFCite
