The phylogenetic evaluation according to the 16S rRNA gene sequences from the chosen isolates and representative species of closely connected taxa formed seven clearly distinguishable clusters (C1, C2, C3, C4, C5, C6 and C7) (Fig 3). The initial cluster (C1) was formed by the strains 48B and 41C using a close connection with genus Bacillus sp. The second cluster (C2) was also connected to Bacillus sp.Azvudine and included five strains (15A, 4A, 47A, 9C, 12A) although the strains 9C and 12A had been slightly extra distant than the other people.Bosentan The third cluster (C3), composed by 46B and 23B, was connected with Gram damaging bacteria which include Sinorhizobium sp. and Pseudomonas fluorescens, respectively. The 32A isolate, grouped inside the fourth cluster (C4), had notably partnership with Paenibacillus massiliensis. The fifth cluster (C5), like 24A and 6C strains, was remarkably related with Paenibacillus sp. and Paenibacillus polymyxa. 39B and 59B isolates had been grouped in to the sixth cluster (C6) with closely relationship with Bacillus sp. and Bacillus megaterium. Surprisingly, the strain 87B was individually grouped forming the cluster (C7) which was associated with any species, even if a 94 of identity was identified with Bacillus sp.

The analysis revealed that soil A was largely linked having a high content material in Olsen P, N-NH4+ and coarse silt while soil B was rather connected to a high CaCO3 and N-NO3- content and soil C was characterized by the presence of coarse and silt sand fractions. Even when soils A and B showed an alkaline pH which differed from soil C (neutral pH values), the PCA evaluation didn’t show any clear relation among pH and sort of soil, as similarly was discovered for the total C and N content. Neither the clay texture nor fine silt was found as properties that intimately characterized the soil A or B. A set o.
