Phylogeny of the study species based on 16S rRNA. The scale bar represents the number of nucleotide substitutions per site. The tree includes the sequences FJ971882 (Enterobacter aerogenes), GQ856082 (Leclercia adecarboxylata), NR_041980 (Serratia marcescens ssp. marcescens), HG326223 (Serratia marcescens ssp. DB11 [whole genome, 16S rRNA part included]), NR_024570 (Escherichia coli), AF094736 (Pseudomonas putida), AF094725 (Pseudomonas fluorescens), AB680102 (Pseudomonas chlororaphis), and NR_025838 (Novosophingobium capsulatum). The sequence accession numbers were obtained from the NCBI nucleotide sequences database
