YouTube video by American Society for Microbiology Fanny Angelina Hesse and the Discovery of Agar

Since the late 19th century, microbiologists have relied on agar and its derivatives for growing and separating microbes. However, how many of us really know the story of how this ingredient changed science? The remarkable story of Fanny Angelina Hesse youtu.be/qyTjqIKTQLo

New in JB: S. aureus is known to incorporate exogenous fatty acids (FA) into its membrane. Menjivar, Bose et al. show that S. aureus has a FA degradation system expressed under catabolite control.

Growth of S. capitata on Sabouraud dextrose agar (left) after 5 days of incubation at 30°C in ambient air produced white, fuzzy colonies. The microscopic morphology stained with lactophenol cotton blue (right) highlights the appearance of oblong annelloconidia clustered at the tips of the annellides, which are located along or at the tips of the hyphae.

#MicrobiologyMonday: Guess the microbe! 🔬🧐

Meet Saprochaete capitata, a yeast-like fungus found in soil. Usually harmless, it can cause severe infections in immunocompromised patients.
