Micrococcus luteus is a Gram-positive to Gram-variable, nonmotile, tetrad-arranging, pigmented, saprotrophic coccus bacterium in the family Micrococcaceae. [1] It is urease and catalase positive. An obligate aerobe , M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin.
Micrococcus is a genus of bacteria in the Micrococcaceae family. Micrococcus occurs in a wide range of environments, including water, dust, and soil. Micrococci have Gram-positive spherical cells ranging from about 0.5 to 3 micrometers in diameter and typically appear in tetrads.
Bacteria characterized by a huge diversity of morphology, starting with color, texture ending with shape of colony and their odor. In this photo we can see a plate with bacterial smears. From the left: Serratia marcescens, at the top: Micrococcus luteus and on the right: Staphylococcus epidermidis.

Colonies of Micrococcus luteus on Tryptic Soy Agar. Cultivation 48 hours, 37°C. Trypticase soy agar or Tryptic soy agar (TSA) is a growth media for the culturing of moderately to non fastidious bacteria. It is a general-purpose, non-selective media providing enough nutrients to allow for a wide variety of microorganisms to grow.
Micrococcus lylae was also first isolated during the same study) [2] In 1995, the species was reclassified into the genus Kocuria as Kocuria kristinae. [3] In 2018, further studies reclassified the species into genus Rothia as Rothia kristinae. [1] R. kristinae is Gram-positive, and the cells are coccoid which tend to group together as tetrads ...
Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes. This article lists some of the species recognized as belonging to the human microbiome and focuses on the oral, vaginal, ovarian follicle, uterus and the male reproductive tract microbiota.
