Phosphine Formation from Sewage Sludge Cultures
نویسندگان
چکیده
Gas-chromatographic analysis of the volatile compounds in the headspace of cultures inoculated with sewage sludge indicated phosphine production over a period of several days, a reaction which is clearly microbiologically mediated. The amounts of phosphine recovered from 40-mL specimens sewage sludge enrichment were in a pg-range of 5 to 100 in the presence of glucose as carbon source and phosphate as phosphorus source. Phosphine accumulation was found to be stimulated by increasing the phosphate concentration of the medium. Hypophosphite and lecithin as phosphorus sources instead of phosphate as well as mannitol and succinic acid instead of glucose as carbon sources affected the phosphine formation.

Co-digestion of cultivated microalgae and sewage sludge from municipal waste water treatment.
In this study two wet microalgae cultures and one dried microalgae culture were co-digested in different proportions with sewage sludge in mesophilic and thermophilic conditions. The aim was to evaluate if the co-digestion could lead to an increased efficiency of methane production compared to digestion of sewage sludge alone. The results showed that co-digestion with both wet and dried microal...
متن کامل4-Nonylphenol in sewage sludge: accumulation of toxic metabolites from nonionic surfactants.
Anaerobically treated sewage sludge was found to contain extraordinarily high concentrations of 4-nonylphenol, a metabolite derived from nonionic surfactants of the nonylphenol polyethoxylate type. Concentrations in activated sewage sludge, in mixed primary and secondary sludge, and in aerobically stabilized sludge were substantially lower, suggesting that the formation of 4-nonylphenol is favo...
متن کاملStudy on Effects of Electron Donors on Phosphine Production from Anaerobic Activated Sludge
The effects of different types and concentrations of electron donors (glucose, starch, methanol and sodium acetate) on the formation of phosphine from anaerobic activated sludge that has been domesticated for a prolonged period were studied in small batch experiments. The results show that types and concentrations of electron donor have significant effects on the production of phosphine from an...
متن کاملEffect of sulfur-containing compounds on anaerobic degradation of cellulose to methane by mixed cultures obtained from sewage sludge.
Tests were made to determine the effects of inorganic and organic sulfur sources on the degradation of cellulose to methane in a chemically defined medium with sulfur-poor inoculum prepared from sewage sludge. The results show that a sulfur source of about a 0.85 mM concentration is essential for the degradation of cellulose to CH4. However, the production of CH4 from CO2 and H2 provided in the...
متن کاملMicroalgae Cultivation on Anaerobic Digestate of Municipal Wastewater, Sewage Sludge and Agro-Waste
Microalgae are fast-growing photosynthetic organisms which have the potential to be exploited as an alternative source of liquid fuels to meet growing global energy demand. The cultivation of microalgae, however, still needs to be improved in order to reduce the cost of the biomass produced. Among the major costs encountered for algal cultivation are the costs for nutrients such as CO₂, nitroge...
