Raw 454-pyrosequencing data of bacterial 16S rRNA gene amplicons of a changing bacterial community composition due to decreasing trace element concentrations

This study aimed to observe changing bacterial community compositions due to trace element deprivation via 454-pyrosequencing of bacterial 16S rRNA gene. Two parallel operated mesobhilic lab-scale biogas reactors are compared. Substrate was DDGS supplemented with an iron additive and cobalt, molybdenum, nickel, and tungsten. After 2 weeks of parallel operation for one reactor (reactor 2) trace element supplementation was denied. For further information about these data and the study we refer to the respective research article: (preliminary title) Trace elements induce predominance among methanogenic activity in anaerobic digestion, Wintsche et al.
