Ganoderma lucidum methanolic extract as a potent phytoconstituent: characterization, in-vitro antimicrobial and cytotoxic activity

mycolabadmin

Researchers tested a medicinal mushroom extract (Reishi/Ganoderma lucidum) to see if it could fight cancer and bacterial infections. The extract showed promising results, being particularly effective against blood cancer and breast cancer cells while being less toxic to normal healthy cells. It also killed bacteria better than some standard antibiotics, suggesting it could potentially be developed into a new type of medicine for treating cancer and infections.

Antioxidant and Enzyme Inhibitory Potential of Streptomyces sp. G-18 Grown in Various Media

mycolabadmin

Researchers studied bacteria called Streptomyces that were isolated from high mountains in Nepal to see if they could produce useful compounds. They grew these bacteria in four different types of growth media and tested the resulting extracts for antioxidant properties and ability to block harmful enzymes. They found that the choice of growth medium significantly affected what compounds the bacteria produced, with one medium (R2YE) being especially effective at producing compounds that could help treat diseases like Alzheimer’s and diabetes.

Characterizing antimicrobial activity of environmental Streptomyces spp. and oral bacterial and fungal isolates from Canis familiaris and Felis catus

mycolabadmin

Researchers collected bacteria and fungi from the mouths of pet dogs and cats, as well as environmental soil bacteria, to search for natural antimicrobial compounds. They found that some of these microorganisms produce substances that can kill harmful bacteria like E. coli and fungi like Candida albicans, especially when combined with existing antifungal medications. Notably, one environmental bacterium (Streptomyces) produced a compound that was even effective against fungal strains resistant to common antifungal drugs, suggesting promising new treatment possibilities.

Screening of Basidiomycete Strains Capable of Synthesizing Antibacterial and Antifungal Metabolites

mycolabadmin

Researchers tested 18 types of medicinal mushrooms to see if they could produce natural antibiotics. Most of them (16 out of 18) showed antimicrobial properties, with some being particularly effective against dangerous bacteria and fungi. The most promising mushroom strain (Hericium corraloides 4) showed strong activity against multiple disease-causing organisms. This research suggests that mushrooms could be valuable sources for developing new antibiotics to fight drug-resistant infections.
