Affiliation of the main sequences retrieved from the predominant DGGE gel fragments with the existing sequences of V3–V5 region of 16S rRNA gene. Sequences belong to soil bacterial communities associated with pot-grown olive trees fertilized with two types of sheep wool residues (SWR) (white wool, WW and black wool, BW), used at 4 different SWR/soil percentages: 0 (C), 0.5, 1.0, 2.0%. Phylogenetic analysis was inferred by using the Maximum Likelihood method based on the Kimura 2-parameter model. Bootstrap (1000 replicates) values below 70 are not shown. Evolutionary analyses were conducted in MEGA X. The sequences from the database are indicated by their accession numbers. The DNA sequences retrieved in this work are indicated by their corresponding band number and their accession number
