Is Kocuria motile?
Kocuria kristinae is a facultative anaerobe and a non-motile, catalase-positive, coagulase-negative and a gram-positive coccus which is arranged in tetrads.
What is the colony morphology of Kocuria rosea?
Morphology. Cells are cocci (1-1.5 µm in diameter) and occur in pairs, tetrads, and clusters. Colonies are circular, slightly convex, smooth (occasionally rough), and pink or red. No water-soluble exopigment is formed.
Is Kocuria rosea catalase-positive or negative?
Kocuria rosea is a non-spore-forming, aerobic, oxidase-negative, catalase-positive, Gram-positive coccoid bacterium which grows as circular, smooth, pinkish colonies on nutrient agar.

Is Kocuria rhizophila motile?
Laboratory identification of Kocuria spp Other physiological and biochemical properties of Kocuria are the formations of non-hemolytic colonies on blood agar, non-capsulated, non-spore forming, non-motile, non-acid fast and positive for Voges-Proskauer test (VP).
Is Roseus Micrococcus motile?
Micrococcus roseus bacterial culture for microbiology laboratory studies are non-motile spheres single, paired and clustered that produce a rose-red pigment.
Is Kocuria rhizophila catalase positive?
Kocuria is non-encapsulated, non-spore-forming and catalase-positive.
Which Enterobacteriaceae are catalase positive?
Colonies of Enterobacter strains may be slightly mucoid. They are catalase positive and oxidase negative. Nitrates are also reduced. They also ferment glucose and lactose with the production of acid and gas.
Which Streptococcus is catalase positive?
StaphylococcusStaphylococcus and Micrococcus spp. are catalase positive, whereas Streptococcus and Enterococcus spp. are catalase negative.
Is Kocuria rosea gram negative?
Kocuria rosea is an aerobic, gram-positive coccus that is generally considered as a non-pathogenic commensal that colonizes the oropharynx, skin, and mucosa.
Is Kocuria rhizophila gram-positive?
The soil actinomycete Kocuria rhizophila is a coccoid, gram-positive bacterium. It belongs to the family Micrococcaceae in the suborder Micrococcineae, a divergent bacterial group for which only limited amount of genomic information is currently available.
Is Kocuria rhizophila gram negative?
Kocuria rhizophila is a coccoid, gram-positive bacterium that belongs to the family Micrococcaceae in the order Actinomycetales.
What is the colony morphology of Serratia marcescens?
Gram stain of Serratia marcescens shows typical "short rod" morphology. Due to limits of resolution using a light microscope, single rods often resemble pairs of cocci or coccoidal cells.
What is the colony morphology of Micrococcus luteus?
Colony Morphology: Colonies are circular, yellow, convex and smooth.
What is the shape and color of each bacterial colony?
Each distinct colony represents an individual bacterial cell or group that has divided repeatedly. Being kept in one place, the resulting cells have accumulated to form a visible patch. Most bacterial colonies appear white or a creamy yellow in colour, and are fairly circular in shape.
What bacteria colony is red?
Serratia marcescens is a forgotten but ubiquitous bacterium that can produce a red pigment called prodigiosin and likes to hang out as a pink film in the shower grout and toilet bowls of less-than-scrupulously clean homes.
