The microbiota of the Mass Bio System (MBS) Targeted Locus (Loci). anaerobic digester metagenome

a Novel Mass Bio System (MBS) was developed for advanced treatment of coal gasification wastewater. A laboratory scale anaerobic AnaEG (Advanced anaerobic expanded granular sludge bed) - primary aerobic BioAX (A novel environmental biotechnological aerobic process with internal circulation) - MBS aerobic fluidized bed nitrification bioreactor - MBS expended bed denitrification bioreactor - secondary aerobic reactor system was operated over a period of 260 days. Pyrosequencing analysis showed the enrichment of ‘rare microbes’. Contrary to expectation, nitrifying bacteria, Ohtaekwangia (Bacteroidetes) was the most abundant rare bacteria 37.1% of the microbial community entrapped in MBS.
