At 37 °C (99 °F) either in the laboratory or in host tissue, S. schenckii assumes its yeast form. Macroscopically, the yeast form grows as smooth white or off-white colonies. Microscopically, yeast cells are 2 to 6 μm long and show an elongated cigar-shaped morphology. [1]
The colony surface is smooth and has a pasty texture. [1] [10] There is considerable cell and colony morphology when S. salmonicolor is grown in culture. [6] The budding yeast-like cells produced during the asexual stage are ellipsoidal to subcylindrical and 8–25 × 2–5.5 μm. They can occur singly or in pairs.
The order comprises fungi that are currently only known from their yeast states, isolated from plant leaves in China. Budding cells in yeast colonies always form rosette-like clusters, hence the name of the order.
Meyerozyma guilliermondii (formerly known as Pichia guilliermondii until its rename in 2010) is a species of yeast of the genus Meyerozyma whose asexual or anamorphic form is known as Candida guilliermondii. Candida guilliermondii has been isolated from numerous human infections, mostly of cutaneous origin, if only from immunosuppressed patients.
The dimorphic form of the species mainly exists and grows vegetatively as either a filamentous hyphae (mould form) or as spherical yeast (yeast form). [2] However, the organism is best known from the mould form which is characterised by the production of asexual reproductive state consisting of tall (up to 2 cm) needle-like sporangiophores with an apical swelling enclosed by a large sporangium ...
Rhodotorula mucilaginosa cells, Methylene blue stain, magnification 400x. Rhodotorula is a genus of fungi in the class Microbotryomycetes.Most species are known in their yeast states which produce orange to red colonies when grown on Sabouraud's dextrose agar (SDA).
Colonial morphology of various specimens of Pseudomonas aeruginosa, including mucoid types. In microbiology, colonial morphology refers to the visual appearance of bacterial or fungal colonies on an agar plate. Examining colonial morphology is the first step in the identification of an unknown microbe.
Malassezia pachydermatis is a bottle-shaped, [2] non-lipid dependent lipophilic yeast in the genus Malassezia. [5] Colonies are cream or yellowish in colour, smooth to wrinkled and convex with a margin possessing a slightly lobed appearance. [5] [8] Cells are ovoidal in shape and range in size from 3.0–6.5 x 2.5 μm. [5]
