| Cross Index | Aerococcus viridans |
| SuperSet | Prokaryote, Eubacteria Gram Positive Cocci |
| Compare | aerobes: Deinobacter grandis Deinococcus,
Marinococcus, Micrococcus,
Planococcus , Salinicoccus roseus facultative anaerobes: Aerococcus viridans, Enterococcus, Gemella haemolysans, Lactococcus Leuconostoc, Melissococcus pluton, Pediococcus, Saccharococcus thermophilus, Staphylococcus, Stomatococcus mucilaginsos, Streptococcus, Trichococcus flocculiformis, Vagococcus anaerobes Coprococcus, Peptococcus niger , Peptostreptococcus, Ruminococcus, Sarcina Catalase positive:Deinococcus, Micrococcus, Planococcus, Staphylococcus,, Stomatococcus mucilaginsosus |
| Contrast | Micrococcaceae are not a coherent group. Micrococcus is closely related to Arthrobacter , Planococcus is related to Bacilluss, while the radioresistant cocci called Deinococcus have atypical Gram positive cell walls. |
