2013
Marcato-Romain, Claire-Emmanuelle | Lefebvre, D. | Godon, Jean-Jacques | Pouech, Philippe
The removal performance of hydrogen sulphide (H2S) in biogas and the bacterial community structure were studied in a pilot-scale codigester. Air and ferric chloride (FeCl3) successfully reduced the H2S content. The bacterial profile obtained by Single Strand Conformation Polymorphism (SSCP) was demonstrably modified after the introduction of air whereas the biogas production (volume, %CH4) was not significantly affected.
