Micrococcus is closely related to Arthrobacter , Planococcus is related to Bacillus, , while the radioresistant cocci called Deinococcus have atypical Gram positive cell walls. |
| Contrast | Archaea |
| Subset | P citreus and P. Kocuri |
| Morphology | Planococcus |
| CELLULAR |
| Staining | Gram-positive |
| Morphology | cocci form pairs or tetrads |
| Motility | actively motile |
| Specialized structures | no spore forming |
| Division |
| COLONIAL |
| Solid surface | Colonies are yellow orange in color |

| Growth Parameters | Planococcus |
| PHYSIOLOGICAL |
| Tropism | |
| Oxygen | strictly aerobic |
| pH | |
| Temperature | 27-37 oC |
| Requirements | Halotolerant will grow in nutrient agar but poor growth less than 1% or more than 15% NaCl compare with Marinococcus |
| Products | Most strains do not attack carbohydrates, reduce nitrate, or hydrolyse esculin, starch or Tween 80 |
| Enzymes | catalase positive and contain cytochromes urease negative |
| Unique features | . There is no teichoic
acid in the cell wall and they are resistent to
lysostaphin and contain phosphatidylethanolamine. P citreus does not grow on nutrient agar containing 20% NaCl and is sensitive to 5 ug of streptomycin Marinococcus contains meso diaminopimelic acid in the cell wall whereas Planococcus contains L-lysine-D-Glutamic acid . |
