Research ArticleOpen accessIn the abstractInvestigation 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 PDFCite
