Fungi: Pioneers of chemical creativity – Techniques and strategies to uncover fungal chemistry

mycolabadmin

This review explores how fungi produce remarkable chemical compounds that have been transformed into important medicines for over a century. Starting with penicillin in the 1940s, scientists have discovered dozens of fungal-derived drugs used to treat infections, prevent organ rejection, lower cholesterol, and fight cancer. Modern technology now allows researchers to discover and analyze these compounds much faster and with smaller samples than ever before.

Thin-Layer Chromatography (TLC) in the Screening of Botanicals–Its Versatile Potential and Selected Applications

mycolabadmin

This review shows how thin-layer chromatography (TLC), a simple laboratory technique, is invaluable for analyzing plant materials. TLC helps scientists identify which plants are related to each other, find beneficial compounds in herbs, ensure herbal medicines are pure and safe, and track illegal psychoactive plants. Despite being less glamorous than modern equipment, TLC remains practical, affordable, and effective for everyday botanical analysis.

Neobacillus terrisolis sp. nov. and Neobacillus solisequens sp. nov. Isolated from Soil

mycolabadmin

Scientists discovered two new species of bacteria in soil from a heavy metal smelting plant in China and named them Neobacillus terrisolis and Neobacillus solisequens. These bacteria can produce hydrogen sulfide, which helps capture and remove toxic heavy metals from contaminated soil. The research shows these microbes could be useful for cleaning up polluted environments through natural biological processes rather than expensive chemical treatments.

Extensive Collection of Psychotropic Mushrooms with Determination of Their Tryptamine Alkaloids

mycolabadmin

Scientists analyzed 226 mushroom samples from about 30 psychotropic species to measure their psilocybin and related compound content. They found that the amounts of these compounds vary greatly, even within the same species, making it difficult to predict how strong a mushroom will be. The research shows that Psilocybe species generally contain the most psychoactive compounds, with some varieties containing over 15 times more psilocybin than others, highlighting safety concerns for users.

First Step on the Way to Identify Dermatophytes Using Odour Fingerprints

mycolabadmin

Researchers have developed a new method to quickly identify fungal skin infections caused by dermatophytes by detecting the unique smells (volatile compounds) they produce. Instead of waiting days or weeks for culture-based tests, this approach uses advanced chemical analysis to create a fingerprint of the fungus based on its odor. The study analyzed 47 different dermatophyte strains and found that each species and even individual strains have distinctive chemical signatures, which could one day allow doctors to diagnose infections rapidly using portable devices similar to electronic noses.
