A higher natural gas price creates slightly less revenue than a higher biogas feed-in tariff.

In 2009, he also started his PhD studies at Leiden University, the Netherlands, focusing on optimal biogas plant feed control.
As facultative anaerobic fungi [37] are widely distributed in the environment, biogas reactors fed by plant material may offer preferable living conditions, even without ruminant manure (c.f. BP1).
After the agitation system was disturbed, foaming and floating layer formation appeared in a full-scale biogas plant fed with liquid manure and biogenic waste.
Other studies on mesophilic codigestion production-scale biogas plants fed with different substrates also reported that hydrogenotrophic methanogens were dominating among the Archaea at DNA level, but in these Methanoculleus representatives were most abundant [64, 65].
Aim of this study was to assess the feasibility of near infrared spectroscopic (NIRS) online monitoring of substrate quality in order to find ways towards more exact control of biogas plant feeding.
Metagenomic DNA from a biogas-producing microbial community residing in the fermenter of an agricultural biogas plant fed with maize silage, green rye and low amounts of chicken manure was recently sequenced on the Genome Sequencer (GS) FLX platform [33].
Community DNA isolated from a production-scale biogas plant fed with maize silage, green rye and low amounts of chicken manure was sequenced on the Genome Sequencer FLX platform which resulted in 142 million base pairs of sequence information.
