Distance phylogram based on near-full-length SSU rRNA gene sequences (approximately 1,490 bp) from FRC isolates (in bold), FRC sediment clone sequences (clone C FB064 I OTU34 was identified from the FRC biostimulated sediment in this study), and other members of Castellaniella as well as related organisms in the order Burkholderiales (accession numbers are shown in parentheses). Bootstrap values are based on 1,000 replicates and are shown for branches with bootstrap support of >50%.
