Localization of Secondary Metabolites in Relict Gymnosperms of the Genus Sequoia In Vivo and in Cell Cultures In Vitro, and the Biological Activity of Their Extracts

mycolabadmin

Researchers studied an ancient giant redwood tree species to extract valuable medicinal compounds. They successfully grew Sequoia cells in laboratory culture that produced powerful cancer-fighting and antifungal substances. These extracts showed promise against cervical cancer and brain tumor cells while being safe to normal cells, offering a sustainable way to harvest these compounds without damaging wild redwood populations.

Application Potential of Lion’s Mane Mushroom in Soy-Based Meat Analogues by High Moisture Extrusion: Physicochemical, Structural and Flavor Characteristics

mycolabadmin

Researchers created a plant-based meat substitute using soy protein and Lion’s Mane mushroom powder processed through extrusion. Adding 20% mushroom powder created the best texture, making it more similar to real meat with visible fibers. The mushroom also improved the flavor, adding mushroom-like aromas and making the product brown better during cooking. This discovery could help make better-tasting plant-based meat alternatives for consumers.

Molecular Regulation of Carotenoid Accumulation Enhanced by Oxidative Stress in the Food Industrial Strain Blakeslea trispora

mycolabadmin

Researchers studied how stressful conditions can make a fungus called Blakeslea trispora produce more carotenoids, which are natural pigments used to color food products. When exposed to chemical stressors like rose bengal or hydrogen peroxide, the fungus produced significantly more carotenoids – up to four times more in some cases. The study identified specific genes and cellular pathways responsible for this increased production, which could help food companies produce natural food colorants more efficiently.

Impact of different drying methods on the quality and flavor of two chili peppers (Capsicum annuum L.) varieties: Chemical composition and volatile compounds

mycolabadmin

This study compared three ways to dry chili peppers and found that each method affects the peppers differently. Hot air drying at 75°C best preserved the spicy compounds and red color, making peppers more nutritious. Shade drying for 12 days created a richer, fruitier aroma with coconut-like flavors. The choice of drying method matters for getting the desired flavor and health benefits in dried chili peppers used for cooking and seasoning.

Quest for Anti-SARS-CoV-2 antiviral therapeutics: in-silico and in-vitro analysis of edible mushroom- Cordyceps militaris

mycolabadmin

Researchers tested an edible mushroom called Cordyceps militaris to see if it could fight SARS-CoV-2, the virus that causes COVID-19. Using computer modeling and laboratory experiments, they found that a compound in the mushroom called cordycepin strongly attached to the virus’s spike protein and reduced viral numbers by about 50% in cell cultures. The study supports traditional uses of this mushroom and suggests it could be helpful in managing COVID-19 as the disease becomes endemic.

Genomic characterization and fermentation study of the endophyte Stemphylium sp. (Aa22), a producer of bioactive alkyl-resorcinols

mycolabadmin

Scientists sequenced the complete genome of a fungus called Stemphylium sp. (strain Aa22) that lives inside wormwood plants without harming them. This fungus produces natural compounds called alkyl-resorcinols that can repel aphids and kill plant-damaging nematodes, making them potentially useful as organic pesticides. The researchers found the genetic instructions for making these compounds and determined that growing the fungus in liquid culture produces more of the useful compounds than growing it on rice, offering a promising path toward developing these natural biopesticides on a larger scale.

Whole Genome Sequence of an Edible Mushroom Stropharia rugosoannulata (Daqiugaigu)

mycolabadmin

Scientists have decoded the complete genetic blueprint of the wine cap mushroom (Stropharia rugosoannulata), a popular edible mushroom grown worldwide. The research identified over 12,000 genes and discovered the mushroom contains powerful enzymes that break down plant material, explaining why it grows so well on straw and corn stalks. The study also revealed that different parts of the mushroom (cap and stem) have different functions, with stems focusing on energy production and caps on growth and development.

Radiation protection and structural stability of fungal melanin polylactic acid biocomposites in low Earth orbit

mycolabadmin

Scientists sent biocomposite materials containing fungal melanin into space for six months to test if they could protect equipment and astronauts from radiation and other harsh conditions. The results showed that fungal melanin-infused materials lost significantly less mass and showed better radiation protection than plain plastics. This research suggests that fungal melanin-based materials could be valuable for long-duration space missions because they are lightweight, biodegradable, and could potentially be grown in space.
