Colony formed conspicuous concentric ring, colony diameter 33 45 mm, colony typically formed abundant conidia with concentric rings, conidia formed dark green color.
Colony forms cottony, colony radius reached 59 69 mm at 25°C, green conidia formed in thick and dense concentric rings, colony formed loose pustules, tending to aggregate towards the distal parts of the colony, few aerial hyphae, mycelia completely filling the Petri dish with dense conidia.
Seven strains producing brown conidia (#46, #47, #48, #67, #68, #72, and #77), four strains producing brownish green conidia (#15, #49, #69, and #71), and six strains producing ring-like colonies that are green at the edge and sand color in the center (#38, #39, #51, #70, #79, and #81) were used for wax moth virulence studies.
The electron microscopy analysis revealed that filamentation (pseudohyphae) was associated with ring and rough colonies.
At the deep central and peripheral depressions areas of the ring and rough colonies extracellular material was seen in different arrangements.
Here, we examined scaling in engineered Escherichia coli that can form self-organized core-ring patterns in colonies.
Within the experimental colonies, rings of fluorescence— indicating the presence of cells on the colonies' peripheries rapidly expressing the aceB gene were observed.
The histogram shows the distribution of spindle angles among all dividing S. rosetta cells measured, with 90° representing perfect alignment relative to the colony ring.
However, when the colony aged after long incubation (greater than 6 days), the conidia in the center of the colony turned light brown while the conidia at the front edge remain the wild type bluish-grey color, giving the colony a ring like look (Figure 6A).
Lipase activity for tributyrin emulsion was determined by the appearance of clear rings around each colony, whereas for Tween-20, lipase activity was based on the formation of a white calcium precipitate.
