Research ArticleOpen accessIn the abstractBiosorption of Ternary Cadmium, Nickel and Cobalt Ions from Aqueous Solution onto Saccharomyces cerevisiae Cells: Batch and Column StudiesMaedeh Galedar, Habibollah YounesiThe aim of this study was to remove cadmium, nickel and cobalt ions from aqueous solutions using yeast, Saccharomyces cerevisiae, pre-treated with ethanol. The cells are immobilized using polysulfone in both batch and continuous systems. To optimize the adsorption capacity of the yeast biomass, a batch system was used to investigate the effects of initial pH, initial biomass dose and … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 7,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractButyrate-Mediated Genomic Changes Involved in Non-Specific Host Defenses, Matrix Remodeling and the Immune Response in the Rumen Epithelium of Cows Afflicted with Subacute Ruminal AcidosisLouis Dionissopoulos, Anne Hermen Laarman, Ousama AlZahal et al.Subacute Ruminal Acidosis (SARA) is a disorder in cattle which can lead to chronic inflammation in the rumen epithelium, known as rumenitis. Butyrate has been shown to attenuate some of the detrimental effects of inflammatory gastroenteral disorders but the molecular mechanisms mediated by butyrate have not been defined. The objective of this study was to define the inflammatory-related genomic changes … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 1 · 10 Jan 2013 · 8,059 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Temperature and Flow Rates of Ozone Generator on the DBD by Varying Various Electrical ParametersBalakrishnan Anantharaman Poonamallie, Lakshminarayanan Vaduganathan, Mahendran NagalingamThis study rationale a high voltage power supply which varies of (O-5) kV with the variable frequency of 50 Hz-5 kHz. The power supply is used in the dielectric barrier discharge tube for the ionization process to yield concentration of ozone.This setup points the development of small and high efficient ozone generators using corona discharge method. Ozone generation was carried … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 6 Aug 2012 · 8,293 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvances in Menaquinone-7 Production by Bacillus subtilis Natto: Fed-Batch Glycerol AdditionAydin Berenjian, Raja Mahanama, Andrea Talbot et al.Menaquinone-7 was produced by fermentation mainly using Bacillus subtilis species. Due to the low concentration of menaquinone-7 in fermentation processes and the associated expense of recovering the menaquinone-7, it was desirable to improve the fermentation concentration. The aim of this study was to determine the effect of fed-batch glycerol addition in the production of menaquinone-7 during the fermentation of Bacillus … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 10,539 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurement of Ground Level Ozone at Different LocationsYasmen A. Mustafa, Sinan J. MohammedProblem statement: Ground level ozone is the most important index substance of photochemical smog. Photochemical smog is now observed in many urban and industrial centers around the world and it has become a common phenomenon in many large cities. Ozone is a most harmful pollutant for humans, in addition it plays an important role in damaging vegetation and materials. Therefore … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 13 Jun 2012 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of E100 to Fuel a Used 4-Stroke MotorcycleT. SuthisripokProblem statement: Though ethanol and gasohol are proved to be used as alternative fuels in vehicles, 4-stoke motorcycles used nationwide mainly consumed gasoline 91/95. Approach: The motorcycle tested, the used Honda Wave125 model, was properly tuned at the rich relative air-fuel ratio (λ) 0.85, which theoretically gave the maximum power output. For the use of E100, the engine required richer … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 23 Feb 2012 · 9,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiofilter Treating Ammonia Gas Using Agricultural Residues MediaThaniya Kaosol, Nutthawut PongpatProblem statement: Agricultural residues such as manure and sugarcane bagasse are wastes from agro-industry which has low value and requires some sustainable waste management method. In this research, a mixture of manure fertilizer and sugarcane bagasse is used as a biofilter media for an ammonia gas removal application. The aim of this research is to study the ammonia gas removal … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 21 Feb 2012 · 7,527 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Diurnally Cyclic Temperature on the Performance of a Continuous Mix Anaerobic DigesterAbdel E. Ghaly, Mariam T. Al HattabProblem statement: Concentrated livestock production is a major contributor to environmental problems through the production of large quantity of husks on relatively small land area. Anaerobic digestion represents a valuable means of cover by these husks into methane while reducing manure pollution problems. Methodology: An experimental apparatus, including data acquisition and control system, was developed and used to investigate the … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 19 Jan 2012 · 9,226 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Some Fermentation Parameters on Ethanol Production from Beet Molasses by Saccharomyces cerevisiae CAIM13Awatif Abid Al-JudaibiProblem Statement: Some component of fermentation medium showed to reduce the Saccharomyces cerivisae production of ethanol. Approach: This study was designed to evaluate the role of some fermentation parameters in affecting ethanol productivity from beet molasses BM by Saccharomyces cerevisiae CAIM13. Results: Increase in cell concentration (inoculums size) of the yeast above 3.6×105 cells/100 mL decreased the ethanol yield. The … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 25 Jun 2011 · 8,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication of Composite Material from Sea Mussel Shells and White Clay as a Versatile SorbentSingto Sakulkhaemaruethai, Churairat Duangduen, Weraporn Pivsa-Art, Sommai Pivsa-ArtProblem statement: The removal of heavy metals contaminated in aqueous solution/wastewater has been causing worldwide concern. However, the adsorbent materials are usually limited due to their high cost and environmentally benign. To overcome the above-mentioned disadvantages, low-cost and effective adsorbents are in demand.
