From this band, ten sequences out of 12 obtained were related to the

genus Curvibacter (class of β-proteobacteria), the two other sequences corresponding to the genus Burkholderidia (class of β-proteobacteria) (Table 5). Three other sequenced bands were visible in all treatments but they increased significantly in intensity at the end of incubation (both B3 and B4 in Vfinal of LA1, B8 in VFfinal of Luminespib manufacturer LB2). These three excised bands were related to the phylum https://www.selleckchem.com/EGFR(HER).html Actinobacteria (with B3 affiliated to the clade acI) (Figure 4 and Table 5). Finally, the three last bands chosen to be sequenced appeared (B5 in Vfinal and VFfinal of LA2) or disappeared (both B6 and B7 in VFAfinal of LB1) at the end of incubation (Figure 4). These ones were all affiliated to the phylum Actinobacteria

(as were 85% of the sequenced DGGE bands). Note that the excised band B1 (LA1 experiment), related to the phylum Cyanobacteria (Table 5), disappeared at the end of the incubation in both VF and V treatments. Table 5 Phylogenetic information about the OTUs
