Nocardiaceae

Rhodococcus fascians, copyright Riraq25.

Belongs within: Corynebacteriales.
Contains: Nocardia.

The Nocardiaceae are aerobic or facultatively aerobic bacteria that may form an extensively branched mycelium (Nouioui et al. 2018).

Characters (from Nouioui et al. 2018): Strictly aerobic or facultatively aerobic, Gram-stain positive to Gram-stain variable, non-motile, catalase-positive, may form extensively branched substrate mycelium that fragments into coccoid to rod-shaped elements, others coccoid or rod-shaped or show a rod-coccus, rod-coccus-mycelium growth cycle. Strains typically acid-alcohol or partially acid-alcohol fast at some stage of growth cycle. Chemo-organotrophic with oxidative metabolism. Peptidoglycan of A1α type. Muramic acid residues of peptidoglycan N-glycolated. Predominant isoprenologues MK-8(H2) or MK-9(H2) or MK-8(H4); major polar lipids DPG PE, PI and PIMs, fatty acids mainly straight-chain saturated, unsaturated and 10-methyloctadecanoic (tuberculostearic) acids. Mycolic acids with between 34 and 64 carbon atoms; fatty-acid esters released on pyrolysis MS of mycolic acid esters with 12–18 carbon atoms. G+C content about 60–75%.
