Enterobacter sp. LR6 showing silicate solubilization on Bunt and Rovira silicate medium (a), phosphate solubilization on NBRIP medium (b), 16s rRNA gene-sequence-based phylogenetic tree constructed using the maximum likelihood method. Based on the 16s rRNA search, the closely related type strain was aligned using ClustalW, and the phylogenetic tree was made using the 1000-bootstrap method. NR_028687.1 Citrobacter braakii strain 167 was selected as the outgroup. The values shown on the tree indicate the bootstrap percentage (c).
