Fungal contaminant, presumably airborne, seen on a TSA plate after 1 month at refrigerated temperatures. White hyphal growth and exudate, water droplets due to respiration, can be seen through the colony. Read More
Different view of an unknown airborne environmental isolate on Bile Esculin Agar (BEA) exhibiting a single circular colony. White hyphal growth with no spore formation. Clear to brownish exudate can be seen throughout the colony. This sample grew at refrigerated temperatures for several months.... Read More

Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and mounding in an irregular-rhizoid form with lobate margins. The colony exhibited an opaque yellow-orange pigment with a mucoid surface. This sample was obtained from a floor swab and incubated at 37°C. Read More
On the first day of Micro class instructors have students do an environmental swab. This sample was subcultured from a student who did the bottom of their shoe. The organism, possible Bacillus sp., was tough to scrap off the agar so subculture was done by taking a small chunk of agar containi... Read More
