Textile residue-based mycelium biocomposites from Pleurotus ostreatus

mycolabadmin

Researchers successfully grew oyster mushroom mycelium on textile waste to create eco-friendly biocomposites that could replace plastic packaging. The fungus naturally binds textile fibers together, creating lightweight materials with useful structural properties. This approach transforms textile waste into sustainable products while addressing plastic pollution, offering a promising solution for converting unwanted clothing and fabric scraps into useful materials.

Optimized production and characterization of red dye from Talaromyces purpureogenus PH7 for application as a textile dye

mycolabadmin

Researchers optimized conditions to produce natural red dye from a fungus called Talaromyces purpureogenus, which could replace harmful synthetic dyes in the textile industry. The dye successfully colored cotton fabrics and resisted fading from washing and sunlight exposure. The fungus also produces beneficial compounds that could improve soil health, making this an environmentally friendly alternative to petroleum-based chemical dyes.

Hydrothermal liquefaction aqueous phase mycoremediation to increase inorganic nitrogen availability

mycolabadmin

When biomass is converted to biofuel through a heating process called hydrothermal liquefaction, it produces a waste liquid containing nutrients but also toxins. Scientists used a type of fungus called Trametes versicolor to clean up this waste and convert the nitrogen into forms that plants can use. After three days of treatment with the fungus, nitrogen levels that plants can use increased dramatically. Adding helpful bacteria further improved the results, making this waste potentially usable as a fertilizer for growing vegetables hydroponically.

Characterization of the Enzymatic and Biosorption Processes Involved in the Decolorization of Remazol Brilliant Blue R Dye by Pleurotus ostreatus Pellets

mycolabadmin

Oyster mushrooms can effectively remove synthetic dyes from wastewater through a combination of absorption and enzymatic breakdown. Researchers tested Pleurotus ostreatus pellets with a textile dye commonly used as a standard pollutant. The mushroom achieved over 98% dye removal, suggesting it could be used in wastewater treatment systems to clean industrial textile effluent. The fungus both absorbs the dye and produces enzymes that break it down.

Cadmium and Lead Tolerance of Filamentous Fungi Isolated from Contaminated Mining Soils

mycolabadmin

Researchers found several types of fungi thriving in extremely contaminated mining soils in Mexico. These fungi can survive in environments with toxic levels of lead and cadmium that would kill most organisms. The most promising fungus, Paecilomyces lilacinus, can tolerate both metals and could potentially be used to clean up heavily polluted mining sites by binding and immobilizing these dangerous metals in the soil.

Identification of novel polyethylene-degrading fungi from South African landfill soils: Arthrographis kalrae, Lecanicillium coprophilum, and Didymosphaeria variabile

mycolabadmin

Researchers in South Africa discovered three previously unknown fungi that can break down plastic waste, particularly low-density polyethylene used in shopping bags. These fungi were isolated from landfill soils and showed the ability to degrade plastic strips through oxidative processes, with chemical changes detectable using advanced analysis techniques. This discovery offers hope for developing local, biologically-based solutions to South Africa’s serious plastic waste problem.

Degradation of Extra-Heavy Crude Oil by Fungi Isolated from Hydrothermal Vents Fields in the Gulf of California

mycolabadmin

Scientists discovered that certain fungi living in deep-sea hydrothermal vents can break down extra-heavy crude oil, a thick and difficult-to-treat form of petroleum. Among eight fungal species tested, Aspergillus sydowii was the most effective, degrading 40% of the crude oil in laboratory conditions. This research suggests these hardy deep-sea fungi could be used as a natural solution to clean up oil spills in extreme marine environments where traditional cleaning methods don’t work well.

Diversity of Culturable Fungi in Two-Phase Olive Mill Waste, a Preliminary Evaluation of Their Enzymatic Potential, and Two New Trichoderma Species

mycolabadmin

Scientists discovered 31 different fungal species living in olive mill waste, including two previously unknown species. These fungi have the ability to break down tough plant materials and remove harmful dyes from waste, making them useful for cleaning up environmental pollution. This research suggests these fungi could be used to transform olive oil production waste into useful products, supporting a circular economy.

Pharmaceutical Pollution in Aquatic Environments: A Concise Review of Environmental Impacts and Bioremediation Systems

mycolabadmin

Medications we take for health are ending up in our water supplies in significant amounts because standard water treatment plants cannot remove them effectively. These pharmaceutical residues are harming wildlife and aquatic ecosystems, causing problems like population declines in birds, developmental issues in fish, and the spread of antibiotic resistance. Scientists are developing new bioremediation technologies, particularly using fungi and mycoremediation, to better remove these drugs from wastewater before they reach our water bodies.

Microbial-Based Green Synthesis of Silver Nanoparticles: A Comparative Review of Bacteria- and Fungi-Mediated Approaches

mycolabadmin

Scientists have developed environmentally friendly ways to create tiny silver particles using bacteria and fungi instead of harsh chemicals. These silver nanoparticles can fight bacteria, help treat cancer, clean contaminated water, and improve food packaging. The review shows that bacteria produce particles quickly but fungi are better for large-scale production and create more stable particles.
