Research ArticleOpen accessIn the abstractEffect of Mixing on the Biological Degradation of Toluene under Aerobic ConditionsAbdel E. Ghaly, D.G. Rushton, K. MartinellThe effectiveness of in-vessel bioremediation in reducing the concentration of toluene in contaminated soil under continuous and intermittent mixing conditions using invessel composting system. The results showed that there was a startup period (60 h) during which the average temperature rose from 21 to 32 and 40°C (and then remained constant) for the bioreactors with continuous and intermittent mixing, respectively. … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction and Identification of Water-Soluble Compounds in Palm-Pressed Fiber by SC-CO2 and GC-MSHarrison Lau Lik Nang, Choo Yuen May, Ma Ah Ngan, Chuah Cheng HockThe residual oil recovered from palm-pressed fiber is known to contain high level of carotenes (4,000 mg kgˉ1 to 6,000 mg kgˉ1) and vitamin E such as tocopherols and tocotrienols (2,000 mg kgˉ1 to 3,000 mg kgˉ1). In this study, the water-soluble compounds in fresh palm-pressed fiber were recovered by supercritical carbon dioxide (SC-CO2) extraction. The concentration of these compounds … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 8,323 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Sustainability of Oil IndustryVera Rocca, Dario VibertiSimilarly to most industrial activities, the oil industry can affect the environment at several stages. The greatest impact is the release of waste into the environment in concentrations that are not natural. Virtually in all cases, the adverse impact can be minimized or eliminated through the implementation of a proper waste management plan. Over the past few years the oil … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 3 Jun 2013 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Ambient Gasess on Respiration of Soil Supporting Four Crops in Central Saudi ArabiaAkram Ali, Ahmad Alfarhan, Ibrahim Aldjain, Nagat BokhariThis study was conducted at four localities (Maseef, Naseem, Oleya and Industrial City) in Riyadh city, KSA to determine the effect of increased tropospheric gases on responses of in situ soil respiration (Rs) of wheat (Triticum aestivum L. cv.

Research ArticleOpen accessIn the abstractT-2 Toxin Regulated Ganoderma lucidum Induced Cytokine ReleaseKazem Ahmadi, Majid RiazipourThe water-soluble extract of Ganoderma lucidum (Reishi) has been used as immunomodulator to stimulate spleen cells proliferation and cytokine expression. It has also been shown that at some level of exposure, T-2 toxin typically act as immunosuppressive agent and can increase disease susceptibility. The aim of this study was to investigate the effect of T-2 toxin on cytokine production by … …American Journal of Immunology, Vol. 4, Issue 1 · 31 Mar 2008 · 7,538 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Light Exposure and Nitrogen Source on the Production of Oil from Freshwater and Marine Water MicroalgaeMariam Al Hattab, Abdel GhalyThe biomass yield and oil content of Chlorella saccharophila (freshwater) and Tetraselmis suecica (marine) microalgae were investigated using various nitrogen source (ammonium nitrate, ammonium phosphate, ammonium sulfate and combination of nutrients) at various light durations (9, 16 and 24 h). NaHCO3 was used as the carbon source. The nitrogen concentration, temperature and pH were maintained at 70 mg/L, 22°C and … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 8 Dec 2014 · 7,265 accessesView PDFCite
