Neighbor-joining phylogenetic tree of 16S rDNA sequences of SV81, S23, S28, S26, S24, S11, and S14 isolates and their closest phylogenetic relatives. The nucleotide sequences used of representative isolates were obtained from Genbank database under the following accession numbers: KF494187 (Azotobacter chroococcum ABA-1), GQ884174 (Stenotrophomonas maltophilia SH-3), MT555732 (Pseudomonas hibiscicola REVAURBS5), KJ729606 (Serratia marcescens 35dr), JQ308605 (Stenotrophomonas maltophilia RPS 4), KF278963 (Stenotrophomonas maltophilia Ysm), JQ308603 (Stenotrophomonas maltophilia PPA N3), KT034429 (Stenotrophomonas sp. 211), KF863899 (Bacillus sp. hb122), JX418320 (Bacillus amyloliquefaciens JBC36), MK928419 (Bacillus velezensis JT4), MT026940 (Bacillus subtilis CBE-22), and for the bacterial isolates tested KR818078 (S11), KR818079 (S14), KR818080 (S23), KR818081 (S24), KR818082 (S26), KR818083 (S28), and KU994900 (Bacillus sp. SV81). The tree topology was constructed using ClustalX (1.81)
