Research ArticleOpen accessIn the keywordsInvestigation of the Photoheterotrophic Hydrogen Production of Rhodobacter sphaeroides KCTC 1434 using Volatile Fatty Acids under Argon and Nitrogen HeadspaceRuby Lynn G. Ventura, Jey-R S. Ventura, Young-Sook OhIn this study, the photo fermentative H2 production of Rhodobacter sphaeroides KCTC 1434 was investigated using acetate, propionate and butyrate under argon and nitrogen headspace gases. The highest H2 yield and Substrate Conversion Efficiency (SCE) were observed from butyrate (8.84 mol H2/mol butyrate consumed, 88.42% SCE) and propionate (6.10 mol H2/mol propionate consumed, 87.16% SCE) under Ar headspace. Utilization of … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 30 Nov 2016 · 9,058 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdsorption Study of Several Hydrophobic Organic Contaminants on an Aquifer MaterialBarbara Ruffino, Mariachiara ZanettiProblem statement: Aim of the present research was to determine coefficient of partition KD between soil and groundwater for five hydrophobic organic pollutants (benzene, chlorobenzene, trichloroethylene-TCE, perchloroethylene-PCE and toluene) in an Italian aquifer material characterized by a low organic carbon content (fOC = 0.00262) by means of laboratory batch tests. Initial aqueous concentrations (quite different among the five compounds) were … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,366 accessesView PDF Cite
