Antifungal Volatile Organic Compounds from Talaromyces purpureogenus CEF642N: Insights from One Strain Many Compounds (OSMAC) Strategy for Controlling Verticillium dahliae in Cotton

mycolabadmin

Scientists discovered that a beneficial fungus called Talaromyces purpureogenus can produce powerful antifungal compounds that kill cotton wilt disease. By growing this fungus on different nutrient media, researchers identified two main antifungal compounds: 3-octanol and 2-octenal. These natural compounds completely or nearly completely stopped the growth of the cotton wilt pathogen in laboratory tests, offering a promising green alternative to chemical pesticides for protecting cotton crops.

Fungal pathogens and symbionts: Living off the fat of the land

mycolabadmin

Certain fungi that live exclusively in or on hosts have evolved a clever survival strategy: they stopped making their own fatty acids and instead steal them from their hosts. This includes fungi that cause pneumonia in immunocompromised patients, yeasts on skin, and beneficial fungi that help plants absorb nutrients from soil. By examining how these fungi scavenge fatty acids from their hosts, scientists hope to develop better treatments and diagnostic tools for fungal infections.

Antifungal Volatile Organic Compounds from Talaromyces purpureogenus CEF642N: Insights from One Strain Many Compounds (OSMAC) Strategy for Controlling Verticillium dahliae in Cotton

mycolabadmin

Scientists discovered that a beneficial fungus called Talaromyces purpureogenus produces natural antifungal compounds that effectively control cotton wilt disease caused by the harmful fungus Verticillium dahliae. The study identified two main compounds, 3-octanol and 2-octenal, that showed strong antifungal activity without synthetic chemicals. This research offers a promising green alternative for protecting cotton crops from one of agriculture’s major diseases while being environmentally friendly.

Immunometabolic reprogramming in macrophages infected with active and dormant Cryptococcus neoformans: differential modulation of respiration, glycolysis, and fatty acid utilization

mycolabadmin

Researchers discovered that when fungal yeast cells enter a dormant state inside immune cells, they trigger different metabolic changes compared to actively growing yeast. While active yeast pushes immune cells to work harder metabolically, dormant yeast causes minimal stress but increases fat uptake by immune cells. This difference may explain how some fungal infections can remain hidden in the body for long periods without causing symptoms.
