Bradyrhizobium denitrificans strain SoilA, isolated from dryland mesquite litter soil in Arizona, USA, grows using calcium oxalate as a sole carbon source

TL;DR

A new strain of Bradyrhizobium denitrificans was found in Arizona desert soil that can grow using calcium oxalate as its only carbon source.

Contribution

The discovery of a Bradyrhizobium denitrificans strain capable of oxalotrophy in dryland environments is novel.

Findings

The isolate was identified as Bradyrhizobium denitrificans through genomic sequencing.

The strain can use calcium oxalate as its sole carbon source.

This finding highlights the potential role of oxalotrophy in dryland ecosystems.

Abstract

A bacterial isolate capable of utilizing calcium oxalate as its sole carbon source was isolated from desert soil to explore the role of oxalotrophy in drylands. Complete genomic sequencing and phylogenomic analysis identified the organism as a strain of Bradyrhizobium denitrificans.
