Immobilization of Acinetobacter sp. A-1 and Applicability in Removal of Difenoconazole from Water–Sediment Systems

mycolabadmin

Scientists discovered a bacterium that can break down difenoconazole, a fungicide widely used in agriculture. They trapped these bacteria in tiny gel beads to make them more stable and effective at cleaning up contaminated water and soil. The immobilized bacteria were more resilient and broke down the pesticide more efficiently than free bacteria, offering a promising natural solution for cleaning up fungicide pollution in the environment.

Ultrasound-assisted extraction and antioxidant activity of polysaccharides from Tenebrio molitor

mycolabadmin

Researchers successfully extracted beneficial compounds called polysaccharides from mealworms (Tenebrio molitor) using ultrasound waves, making the process faster and more efficient than traditional methods. These extracted polysaccharides demonstrated strong antioxidant properties, meaning they can help neutralize harmful free radicals in the body. The study shows that mealworm polysaccharides could be used as natural health supplements or food additives with health benefits comparable to or better than Vitamin C.

Synbiotic microencapsulation of Lactiplantibacillus plantarum-lentinan for enhanced growth in broilers

mycolabadmin

Researchers developed a special protective coating for beneficial bacteria called L. plantarum mixed with lentinan from mushrooms. This mixture helps chickens grow better and stay healthier by improving their digestion and fighting harmful bacteria. When the coated bacteria reach the chicken’s intestines, they release their beneficial properties, improving growth rate and immune function without using antibiotics.

Soy Sauce Fermentation with Cordyceps militaris: Process Optimization and Functional Profiling

mycolabadmin

Researchers created a new type of soy sauce using Cordyceps militaris fungus, which contains health-promoting compounds. Using scientific optimization techniques, they found the best conditions for fermentation, resulting in a soy sauce with much higher levels of cordycepin and other beneficial compounds compared to traditional soy sauce. This product offers both the familiar taste of soy sauce and added health benefits, potentially serving as a functional food that people can use daily.

The application of laccase-rich extract of spent mushroom substrates for removing lignin from jute fabric waste: a dual management approach

mycolabadmin

This research shows how leftover mushroom growing material (SMS) can be recycled into a useful enzyme called laccase to make jute fabric softer and lighter by removing tough lignin components. Instead of using harsh chemicals, the scientists used mild conditions and natural enzymes to process jute waste sustainably. From just one bag of mushroom waste, they could treat an area of fabric equivalent to 2000 square meters, making this an economically attractive solution for both mushroom and textile waste management.

Statistical optimization of crude oil bioremediation using Streptomyces aurantiogriseus isolated from Egypt’s Western Desert

mycolabadmin

Researchers from Egypt isolated a special type of bacteria called Streptomyces aurantiogriseus that can break down crude oil and remove it from contaminated soil. Using scientific optimization techniques, they found the best conditions for this bacteria to work most effectively, achieving 92% oil removal in soil experiments. This eco-friendly approach offers a sustainable solution to clean up oil-polluted environments without harmful chemicals.

Enhancement of Mycelial Growth and Antifungal Activity by Combining Fermentation Optimization and Genetic Engineering in Streptomyces pratensis S10

mycolabadmin

Scientists improved a soil bacterium called Streptomyces pratensis S10 that fights a serious wheat disease called Fusarium head blight. They used two strategies: first, they optimized the growth medium using statistical methods to produce more bacteria with stronger antifungal powers, and second, they used genetic engineering to remove a gene that was limiting its disease-fighting ability. The result was a bacteria strain that is much more effective at controlling this crop disease.

Edible Fungi Melanin: Recent Advances in Extraction, Characterization, Biological Activity and Applications

mycolabadmin

Melanin from edible mushrooms like black wood ear and reishi offers a natural, sustainable alternative to synthetic melanins with impressive health benefits. These mushroom melanins demonstrate powerful antioxidant and antibacterial properties, protect against radiation damage, and can help maintain liver health. New extraction methods using special solvents are making it easier to obtain pure melanin from mushrooms efficiently, opening doors for its use in food, cosmetics, and medicines.

Extraction, physicochemical properties, and antioxidant activity of natural melanin from Auricularia heimuer fermentation

mycolabadmin

Researchers optimized a method to extract melanin, a natural black pigment, from fermented wood ear mushrooms (Auricularia heimuer). Using microwave-assisted extraction with specific pH conditions, they achieved a 0.4% yield of pure melanin. The extracted melanin showed strong antioxidant properties and could be used as a natural, safe colorant and antioxidant in food and pharmaceutical products.

Optimization of triterpenoids biosynthesis in Athelia termitophila as a source of natural products

mycolabadmin

Researchers optimized growing conditions for a parasitic termite fungus called Athelia termitophila to produce more triterpenoids, which are medicinal compounds with health benefits. By systematically testing different nutrients and fermentation parameters, they increased triterpenoid production by 1.9 times and fungal biomass by 1.66 times. This breakthrough makes it more practical and cost-effective to produce these natural compounds for use in pharmaceuticals and functional foods.
