AWMC Seminar Program: Rasmus Kirkegaard

Visiting student Mr. Rasmus Kirkegaard from Aalborg University in Denmark presents this week for the AWMC seminar.
Mr Kirkegaard is currently working on the Nomigas project under the supervision of AWMC Deputy Director Professor Damien Batstone.

Novel microorganisms in anaerobic digesters
Anaerobic digestion is an important biological process driven by a mixed community of microbes. Different microbial groups carry out the different steps in the sequential conversion of complex biomass into carbon dioxide and methane. Here we present a microbial survey of 18 Danish full-scale wastewater treatment plants performing anaerobic digestion with a total of 32 reactors sampled during a period of four years.

The comprehensive survey is based on high throughput sequencing of 16S rRNA gene amplicons providing identity and abundance of all the microbes in each of the 250+ samples. The microbial community analysis revealed that thermophilic and mesophilic digesters contain very distinct microbial communities and among the list of “well-known” bacteria, some of the abundant microorganisms turned out to be completely unknown. Using metagenome sequencing we explored the potential for retrieving genomic information for the novel microorganisms to improve the understanding of the underlying microbiology of anaerobic digestion.
