| 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 |

| Temperature | The optimum temperature fro growth is 37-42 C |
| Requirements | |
| Products | Carbohydrates are fermentable substrates with the formation of acetate, succinate, lactate, ethanol, carbon dioxide and hydrogen. Amino acids and peptides are not fermented., nitrate is not reduced and ammonia is not produced from amino acids or peptides. Butyrate is not a fermentable product indole is not produced |
| Enzymes | Catalase negative |
