  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Chromicrobium".
  • 🎰 The BRCs most frequently used for deposits in this group are: KCTC: 1; JCM: 1; KACC: 1; DSM: 1; CCTCC: 1; LMG: 1; MTCC: 1; MCC: 1; CGMCC: 1; NBRC: 1.
  • 🧍 The authors did not explicitly assign the genus to a family but noted its close phylogenetic placement to Acaricomes and Renibacterium, which at that time were already assigned to Micrococcaceae. Publication: Pukall R, Schumann P, Schutte C, Gols R, Dicke M. Acaricomes phytoseiuli gen. nov., sp. nov., isolated from the predatory mite Phytoseiulus persimilis.
