How-to guide: Minimum Inhibitory Concentration (MIC)
For many years, the Kirby-Bauer disk diffusion method accounted for most susceptibility tests. Using the Kirby-Bauer method, a zone of inhibition (where bacteria did not grow) could be identified and…

Separation and Identification of alpha- and beta-glycopyranoside anomers
Many natural products consist of a protein, peptide, or a small molecule which has been glycosylated. These glycosylations can happen for a variety of reasons, including cell-cell recognition of glycosylated…
Fungi: They’re Everywhere!
Fungal spores are commonplace in households and many work environments. In small quantities to healthy people, there are no adverse effects. In large quantities or in immunocompromised individuals, it can…
Yeast: It’s Not Only Found in Food
