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
In this post, I meet up with six of my former undergraduate students at the General Meeting of the American Society of Microbiology in Boston last May. We had a great dinner where we could catch up on challenges and cheer each other on. I am very proud of the great students in this post, who a... 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
A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More
Bacteria has the virtue (and sometimes the vice) of being able to grow at incredible speeds—some strains can double in cell count in as little as four minutes. Fernan Federici, a postdoctoral student at the University of Cambridge, is pioneering the art of capturing the split-second process. And... Read More
Growth of Acetobacter pasteurianus on glucose, yeast extract, calcium carbonate, ethanol medium.
Formation of acetic acid from ethanol oxidation is shown by a clear halo around bacterial growth due to dissolution of calcium carbonate.
