## Abstract The effect of nitrate, nitrite, nitric oxide (NO), and nitrous oxide on a mixed, mesophilic (35Β°C) methanogenic culture was investigated. Shortβterm inhibition assays were conducted at a concentration range of 10β350 mg N/L nitrate, 17β500 mg N/L nitrite, 0.02β0.8 mg N/L aqueous NO, and

β¦ Synopsis
Methanogenic enrichment cultures degrading lignocellulose, propionate, acetate, and I-L-CO: were adapted to media of various salinities and specific growth rates were determined. NaCI concentrations up to 0"25 M had little effect on growth rate of propionate-, acetate-, or tt2-CO:-degrading cultures, but the growth rate of lignocellulose-degrading populations was about 50% inhibited by 0"25 M NaCL

This work evaluates filtration followed by consolidation characteristics of sodium chloride containing activated sludge. Experimental results indicate that contact time and salinity level affect the dewatering efficiency. Considering the consolidation stage, a critical salinity level (around 1-2% (w
## Abstract The effect of sulfide on nitrate reduction and methanogenesis was investigated in two mixed, mesophilic (35Β°C) methanogenic cultures: sulfideβfree and sulfideβacclimated (67 mg S/L total sulfide). A mixture of dextrin/peptone served as the carbon/electron donor source for the two stock
