Micrococcus is closely related to Arthrobacter , Planococcus is related to Bacillus, , while the radioresistant cocci called Deinococcus have atypical Gram positive cell walls. |

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 . |
