Raw sequencing data associated with a paper. Enrichment of a termite-originated bacterial community in bioreactor under anareobic conditions, with wheat straw as sole carbon source. Data produced with an Illumina MiSeq Samples names : (a and b stand for biological replicates) - GUTS : Nasutitermes ephratae gut content (rDNA) - TM : community final state after the first cultivation cycle (rDNA) - NSS-Cn : community final state after n cultivation cycles with non-sterile straw (rDNA) - SS-Cn : community final state after n cultivation cycles with sterile straw (rDNA) - TWS_dayN : active community state at day N (rRNA)
