Microbio. 1664-302X 10.3389/fmicb.2020.00468 32373076 From DSMZ (Markus): Bradyrhizobiaceae Garrity et al. 2006 is illegitimate because the family contains the genus Nitrobacter Winogradsky 1892 (Approved Lists 1980) which is the type of the family Nitrobacteraceae Buchanan 1917 (Approved Lists 1980). Hördt et al. 2020 asserts that this family is illegitimate but does not cite a specific rule that is contravened in the Code.
