Structure and Activity of microbial communities in biogas reactors

Biogas is a valuable renewable energy source. It is produced by a complex community of different bacteria and archaea. When nitrogen-rich substrates are utilized, the involved microorganisms are inhibited due to high levels of ammonia. A mechanistic explanation for this inhibition is still missing. However, it would give important insight into the understanding and control of the biogas process. In this project molecular biological methods will be applied to study the composition and dynamics of microbial communities at different ammonia and acid concentrations in lab-scale biogas reactors. Suitable methods are:

  • DNA and RNA extraction
  • T-RFLP-Fingerprinting of different genes (16S rRNA and mcrA)
  • Statistical evaluation
  • Optional: Application of the mathematical model ADM1

Your profile:

  • Studies of biology, biochemistry, environmental or related sciences
  • Highly motivated
  • Ability to work independently

We offer:

  • insights into a very important research topic
  • access to well-equipped isotope and molecular biology laboratories
  • hands-on experience on a wide range of molecular techniques and stable
  • isotope measurement methods
  • dedicated supervision
