Micrococci have Gram-positive spherical cells ranging from about 0.5 to 3 micrometers in diameter and typically appear in tetrads. They are catalase positive, oxidase positive, indole negative and citrate negative. Micrococcus has a substantial cell wall, which may comprise as much as 50% of the cell mass.

Micrococci are Gram-positive, spherical psychrotrophic cells, which are thermoduric (heat resistant). They are catalase-positive, oxidase-positive, and citrate negative. They are not usually pathogenic and may form a main part of the raw milk microbiota.

Micrococci are catalase-positive, oxidase-positive, strictly aerobic Gram-positive cocci that grow in clusters. On sheep blood agar they form cream-colored to yellow colonies. Resistance to mupirocin and staphylolysin, and susceptibility to bacitracin and lysozyme differentiate them from the staphylococci.

The basic criteria for distinguishing among catalase‐positive Gram‐positive cocci and their relatives as well as other microbial taxa are given in “Description of the Families” above and in…

2017年1月1日 · The genus Micrococcus consists of Gram-positive spheres occurring in tetrads and in irregular clusters that are usually nonmotile and nonsporeforming. They are catalase positive and usually aerobic with strictly respiratory metabolism.

2011年5月16日 · Historically, the genera Staphylococcus and Micrococcus were placed together with the genera Stomatococcus and Planococcus in the family Micrococcaceae containing grampositive, catalase-positive cocci.

The crystal structure of the bacterial catalase from Micrococcus lysodeikticus has been refined using the gene-derived sequence both at 0.88 A resolution using data recorded at 110 K and at 1.5 A resolution with room-temperature data. The atomic resolution structure has been refined with individual …

Micrococcus is chemo-organotrophic with strictly respiratory metabolism, and is catalase- and oxidase-positive. Optimal growth temperature is 25–37°C. Micrococcus is non-halophilic. The cytochromes are aa 3, b 557, b 567 and d 626; cytochromes c 550, c 551, b 563, b 564 and b 567 may be present. Mycolic acids and teichoic acids are absent.
