title: BEL-sludge- seed
design: The bacteria samples with the file name of BES_10, CK_10 represent bacteria isolated form sludge in a bioelectrochemical system and a biological system, both of which were operated at 10?. The bacteria samples with the file name of B_30, C_10 represent bacteria isolated form sludge in a bioelectrochemical system and a biological system, both of which were operated at 10?. The archaea samples represent archaea isolated form sludge in the same bioelectrochemical system and the biological system operated at 10? The  sample with the file name of  seed represent bacteria isolated form inoculated sludge, which was collected form a wastewater plant treating organic fluorine wastewater. Both of these systems were operated for fluoronitrobenzene treatment.
