TABLE 2.

Composition of the microbial community structure of the different consortia as determined by 16S rRNA gene clone libraries

Strain	% of clones with same 16S rRNA gene insert
	Linuron-degrading culture (51 mo old)	3,4-DCA-degrading culture (4 mo old)	N,O-DMHA-degrading culture (4 mo old)
Variovorax sp. strain WDL1	24
D. acidovorans WDL34	38	70
Pseudomonas sp. strain WDL5	0a	30
H. sulfonivorans WDL6	25		100
Other bacteria	13

^aDetermined as 0%, although the WDL5 band was clearly visible in the DGGE pattern.
