The colony growing on a medium with oxalate as sole source (a) and scanning electron micrograph of isolate TA1 (b). The phylogenetic tree, based on 16S rRNA gene sequence using the Neighbour-joining method, showed the phylogenetic relationship of the isolate TA1 was related with the species of Methylobacterium thiocyanatum and bootstrap values calculated from 1000 repetitions are included at the nodes (c). SEM (d), EDS (e) and XRD (f) of crystals from calcium oxalate-containing liquid King’s B medium.
