- What is the carbon to nitrogen ratio of polyacrylamide?
- Polyacrylamide was the only added nitrogen source. Benzoate or acetate was added as a carbon source (about 1000 mg L −1) and after the medium was sterilized by autoclaving, a portion of non-sterile polyacrylamide stock solution (3000 mg L −1) was added to give a final carbon:nitrogen mass ratio of 20:1.
- Does polyacrylamide stimulate methanogenesis?
- Haveroen ME, MacKinnon MD, Fedorak PM (2005) Polyacrylamide added as a nitrogen source stimulates methanogenesis in consortia from various wastewaters. Water Res 39:3333–3341 Hirrlinger B, Stolz A, Knackmuss HJ (1996) Purification and properties of an amidase from Rhodococcus erythropolis MP50 which enantioselectively hydrolyzes arylpropionamides.
- Does anionic polyacrylamide stimulate methanogenesis in serum-bottle microcosms?
- This study assessed whether methanogenesis was stimulated when an anionic polyacrylamide (Magnafloc ® LT27AG) was the sole fixed nitrogen source in serum-bottle microcosms. Microorganisms from two oil sands tailings sources, and a domestic anaerobic sewage sludge were used, with benzoate or acetate provided as carbon and energy sources.
- How much fixed nitrogen is supplied by polyacrylamide?
- The amount of fixed nitrogen supplied by the polyacrylamide was 20 mg N L −1, giving a biomass-carbon:nitrogen mass ratio of 1. Therefore, each of the microcosms had a slight excess of fixed nitrogen from polyacrylamide.
