The micrococcaceae The family Micrococcaceae contains gram-positive cocci,0.5-2.5 um in diameter, that divide in more than one plane to form regular or irregular clusters of cells All are aerobic or facultatively anaerobic. The peptidoglycan di-amino acid is L-lysine The three most important genera are: Micrococcus Staphylococcus Streptococcus

Micrococcus-aerobic, gram-positive catalase positive, cell arranges mainly in pairs tetrads, or irregular clusters, nonmotile. They are often yellow, orange or red in colour
Micrococcus – aerobic, gram-positive, catalase positive, cell arranges mainly in pairs, tetrads, or irregular clusters, nonmotile. They are often yellow, orange or red in colour
Staphylococcus- facultatively anaerobic, gram positive, usually form irregular clusters, nonmotile, catalase positive but oxidase negative, ferment glucose anaerobically staphylococci staphylococci
Staphylococcus - facultatively anaerobic, grampositive, usually form irregular clusters, nonmotile, catalase positive but oxidase negative, ferment glucose anaerobically. staphylococci staphylococci
Streptococcus facultatively anaerobic or microaerophilic, catalase negative, gram-positive ell arranges in pairs or chains, usually nonmotile, A few species are anaerobic rather than facultative
