The Effect of Supplementing Mushroom Growing Substrates on the Bioactive Compounds, Antimicrobial Activity, and Antioxidant Activity of Pleurotus ostreatus

mycolabadmin

This study investigated how adding wheat bran to mushroom growing substrates affects oyster mushroom quality and medicinal properties. The researchers found that wheat bran supplementation increased mushroom yield but slightly decreased antioxidant power, while the mushrooms produced antimicrobial compounds effective against various bacteria and fungi. The mushrooms contained beneficial compounds like vitamin E and phenols, suggesting they could be developed as natural alternatives to synthetic antibiotics.

The Application of Fungi and Their Secondary Metabolites in Aquaculture

mycolabadmin

Fungi can help solve several problems in fish farming. They can make plant-based fish feed more nutritious and easier to digest, boost fish immune systems and disease resistance without antibiotics, help fish feed float better in water, and clean up polluted water from fish farms. This makes aquaculture more sustainable and environmentally friendly while reducing costs for farmers.

Koumiss (Fermented Mare’s Milk) as a Functional Food: Bioactive Proteins, Peptides, and Future Perspectives

mycolabadmin

Koumiss is a fermented mare’s milk beverage consumed for centuries in Central Asia that offers unique health benefits. Unlike cow’s milk, mare’s milk is easier to digest, contains natural antimicrobial proteins, and when fermented develops thousands of bioactive peptides and beneficial bacteria. These compounds may help with cardiovascular health, gut function, and immune support, making koumiss a promising functional food for modern nutrition.

Nanoencapsulation of Biotics: Feasibility to Enhance Stability and Delivery for Improved Gut Health

mycolabadmin

This review explores how tiny nanoparticles can protect beneficial bacteria and dietary compounds as they travel through the digestive system. These nanotechnologies help probiotics survive stomach acid and reach the intestines where they provide health benefits. The research shows promising results for treating digestive diseases and improving overall gut health through better delivery of microbiota-modulating substances.

Isolation of Actinobacteria from Date Palm Rhizosphere with Enzymatic, Antimicrobial, Antioxidant, and Protein Denaturation Inhibitory Activities

mycolabadmin

Researchers isolated bacteria called actinobacteria from soil around date palm roots in Algeria’s Sahara Desert. One promising strain, Streptomyces sp. SGI16, was found to produce multiple enzymes and compounds with strong antimicrobial and antioxidant properties. These findings suggest desert microorganisms could be valuable sources for developing new medicines and agricultural products.

Cultivation and mycelium production from spore suspensions of desert truffles: prospective use as inoculum for host plants in arid zones

mycolabadmin

Desert truffles are valuable edible fungi that grow in arid regions and have health benefits. This research successfully grew two desert truffle species (Terfezia boudieri and Tirmania nivea) in laboratory conditions using standard culture media. The study found that potato dextrose agar was the best medium for rapid growth, while both media supported good mycelial development. This breakthrough could enable large-scale production of truffle inoculum for reforestation programs in Morocco’s degraded desert areas.

Alginate Edible Films Containing Essential Oils: Characterization and Bioactive Potential

mycolabadmin

Scientists created edible films made from alginate (a natural material from seaweed) mixed with essential oils from plants like oregano, thyme, and rosemary. These films could replace plastic packaging for food and have natural antibacterial and antioxidant properties. The oregano oil film worked best, completely stopping the growth of harmful bacteria and fungi while protecting food from oxidative damage.

Antimicrobial Activity and Barrier Properties against UV Radiation of Alkaline and Enzymatically Treated Linen Woven Fabrics Coated with Inorganic Hybrid Material

mycolabadmin

Scientists treated linen fabric with an enzyme from a fungus called Cerrena unicolor combined with copper and silica particles to create advanced protective textiles. The resulting fabrics provide excellent protection against harmful UV radiation and kill dangerous bacteria and fungi like E. coli, Staph, and Candida. This eco-friendly approach could be used for protective clothing, outdoor gear, and medical textiles requiring both UV and microbial resistance.

Biological Activities of Secondary Metabolites from the Edible-Medicinal Macrofungi

mycolabadmin

This comprehensive review examines over 270 bioactive compounds from edible and medicinal mushrooms, showing they have remarkable potential to treat various diseases. These mushroom-derived substances demonstrate effectiveness against cancer, diabetes, inflammation, and infections while having fewer side effects than conventional drugs. Families like reishi and shiitake mushrooms are particularly rich sources of these healing compounds. The research suggests mushrooms are valuable natural resources for developing new therapeutic treatments.

Antioxidant, Antibacterial and Dyeing Potential of Crude Pigment Extract of Gonatophragmium triuniae and Its Chemical Characterization

mycolabadmin

Scientists discovered a rare orange-pigment-producing fungus called Gonatophragmium triuniae that has useful medicinal and practical applications. The fungus produces a natural pigment that can kill bacteria, protect against oxidative damage, and effectively dye cotton fabrics without toxic chemicals. The main active compound was identified as a phenoxazine derivative, suggesting potential uses in textiles, pharmaceuticals, and natural cosmetics as a safe alternative to synthetic pigments and antibiotics.
