<i>Rhodococcus navarretei</i> sp. nov. and <i>Pseudarthrobacter quantipunctorum</i> sp. nov., two novel species with the ability to biosynthesize fluorescent nanoparticles, isolated from soil samples at Union Glacier, Antarctica.

ABSTRACT: Two Gram-stain-positive bacterial strains, EXRC-4A-4^T and RC-2-3^T, were isolated from soil samples collected at Union Glacier, Antarctica. Based on 16S rRNA gene sequence similarity, strain EXRC-4A-4^T was identified as belonging to the genus Rhodococcus, and strain RC-2-3^T to the genus Pseudarthrobacter. Further genomic analyses, including average nucleotide identity and digital DNA-DNA hybridization, suggested that these strains represent new species. Strain EXRC-4A-4^T exhibited growth at temperatures ranging from 4 to 28 °C (optimum between 20 and 28 °C), at pH 5.0-9.0 (optimum, pH 6.0), and in the presence of 0-5.0% NaCl (optimum between 0 and 1% NaCl). Strain RC-2-3^T grew at 4-28 °C (optimum growth at 28 °C
