Cross Index Planococcus
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,Marinococcus Micrococcus, Planococcus, Staphylococcus,, Stomatococcus mucilaginsosus

Micrococcaceae are not a coherent group. Micrococcus is closely related to Arthrobacter , Planococcus is related to Bacillus, , while the radioresistant cocci called Deinococcus have atypical Gram positive cell walls.

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
