Semi-industrial scale mixed alcohol bioreactor communities
16S rRNA gene characterization of microbial communities associated with a semi-industrial scale lignocellulosic bioreactor system that produces mixed alcohols
The goals of this study were to 1) identify the organisms present in the reactor communities and 2) track their changes over time. Samples of reactor liquid were collected at days 0 (marine sediment inoculum), 7, 30, 48, 62, and 78 of an 80-day fermentation run. Community DNA was extracted from the sediment and reactor broth and submitted to the Research and Testing Laboratory (MBRI, Lubbock, TX) for 16S rRNA pyrotag sequencing. This data set contains partial 454 sequencing runs of 16S rRNA data for each of the time points listed above.
Bacterial communities associated with a semi-industrial scale, anaerobic bioreactor facility were sequenced at six time points across an 80-day batch fermentation of high biomass bioenergy sorghum. These communities included periods during which reactor productivity was ramping up, at peak productivity, and in decline, as well as the marine sediment that was used as an inoculum source for the reactor facility.
