Research ArticleOpen accessIn the abstractEffect of Pressure, Water Depth and Water Flow Rate on Oxygen Saturation Level in Activated Sludge ProcessNabil N. Atta, Amro A. Elbaz, Alhassan H. SakrProblem statement: The role of aeration in activated sludge process is to provide oxygen to microorganisms as they assimilate the organic carbon compounds and digest a portion of them to carbon dioxide and water, sulfate and nitrate compounds. The water aeration equipment used in this process consumes as much as 60-80% of total power requirements in modern wastewater treatment plants. … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 21 Dec 2011 · 8,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioautography Guided Identification of Anticandidal Compounds from A. terreus st. 1B. K. Nagaraja, R. Sripathy, C. N. Ramchand, M. SundararamanProblem statement: Saprophytic and soil inhabiting microorganisms are prolific producers of secondary metabolites with wide range of structural and functional diversity. The objective of the current study was to screen and evaluate the anti-candidal properties of soil inhabiting fungi. Approach: Preliminary dual culture assay and bioautography was used to screen the fungi with potential anti-fungal activity and direct detection of … …American Journal of Infectious Diseases, Vol. 7, Issue 4 · 1 Dec 2011 · 7,629 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.
