This image depicts a Petri dish culture plate that contained a growth medium of Sabouraud dextrose agar (SDA), which had been inoculated with a culture of Aspergillus tamarii fungal organisms, and after having been incubated for an unknown period, gave rise to this yellow-green to olive-brown colored colony exhibiting a roughened texture. Note that the central region of the colony had begun to turn darker-brown with age, with brown rings emanating concentrically from the colony’s center.
A. tamarii has uses in the food industry in the production of various types of soy sauce. In the fermentation industry, this organism is also used in the production of a number of fermentative enzymes including amylases, proteases, and xylanolytic enzymes. Though rarely found to be a human pathogen, A. tamarii has been identified as the pathogen in a case of fungal keratitis, invasive nasosinusal aspergillosis in the case of an immunocompromised patient, and onychomycosis, or nail infection, in a 3-year-old boy.
