Acclimatization of a mixed-animal manure inoculum to the anaerobic digestion of Axonopus compressus reveals the putative importance of Mesotoga infera and Methanosaeta concilii as elucidated by DGGE and Illumina MiSeq

- Multifarious inoculum acclimatized to digesting cowgrass.
- Perturbation of community structure after acclimatization.
- Microbial community tracked with DGGE and Illumina MiSeq.
- Putative importance of Mesotoga infera and Methanosaeta concilii in AD of grass.

In this study, a multifarious microbial mix from different sources is acclimatized over a period of three months to digesting cowgrass, and the changes in the community structure are examined with both a traditional denaturing gradient gel electrophoresis method as well as a next generation sequencing MiSeq method. It is shown that the much more in depth analysis by Illumina gives more information about the relative abundance and thus putative importance of the role of various microbes, in particular the bacterium Mesotoga infera and the archaeon Methanosaeta concilii.
