Title: | Harvesting biohydrogen from cellobiose from sulfide or nitrite-containing wastewaters using Clostridium sp. R1 | Authors: | Ho K.-L. Lee D.-J. |
Keywords: | Cellobiose;Clostridium;Hydrogen;Nitrite;Sulfide | Issue Date: | 2011 | Journal Volume: | 102 | Journal Issue: | 18 | Start page/Pages: | 8547-8549 | Source: | Bioresource Technology | Abstract: | Harvesting biohydrogen from inhibiting wastewaters is of practical interest since the toxicity of compounds in a wastewater stream commonly prevents the bioenergy content being recovered. The isolated Clostridium sp. R1 is utilized to degrade cellobiose in sulfide or nitrite-containing medium for biohydrogen production. The strain can effectively degrade cellobiose free of severe inhibitory effects at up to 200mgl -1 sulfide or to 5mgl -1 nitrite, yielding hydrogen at >2.0mol H 2 mol -1 cellobiose. Principal metabolites of cellobiose fermentation are acetate and butyrate, with the concentration of the former increases with increasing sulfide and nitrite concentrations. The isolated strain can yield hydrogen from cellobiose in sulfide-laden wastewaters. However, the present of nitrite significantly limit the efficiency of the biohydrogen harvesting process. ? 2011 Elsevier Ltd. |
