Harnessing and Degradation Mechanism of Persistent Polyethylene Waste by Newly Isolated Bacteria from Waxworm and Termite Gut Symbionts

mycolabadmin

Researchers discovered that bacteria living in the guts of waxworms and termites can effectively break down plastic waste, particularly low-density polyethylene (LDPE) commonly found in plastic bags and packaging. Two bacterial strains—Bacillus cereus from waxworms and Pseudomonas aeruginosa from termites—were tested for their ability to degrade LDPE. The Bacillus cereus strain proved more effective, breaking down nearly 20% of the plastic over 45 days by forming biofilms and using enzyme-producing capabilities. These findings suggest a promising biological approach to managing plastic pollution that could complement traditional recycling methods.

Mycoremediation of anthraquinone dyes from textile industries: a mini-review

mycolabadmin

Textile factories create large amounts of harmful wastewater containing dyes that damage water ecosystems. Scientists have discovered that certain mushroom fungi can naturally break down these toxic dyes using special enzymes. By growing these fungi on support materials, the treatment becomes even more effective and can be reused multiple times, offering an eco-friendly and cost-effective solution for cleaning contaminated water.

Systematic Evaluation of Biodegradation of Azo Dyes by Microorganisms: Efficient Species, Physicochemical Factors, and Enzymatic Systems

mycolabadmin

Azo dyes used in textiles and fashion contaminate water supplies and pose health risks including cancer potential. This research review shows that certain microorganisms like specific fungi and bacteria can break down these harmful dyes into less toxic substances through natural enzymatic processes. By optimizing conditions like pH and temperature, and using combinations of different microbes, scientists have achieved degradation rates up to 90%, offering an eco-friendly and cost-effective alternative to traditional chemical treatment methods.

Breaking Down Linear Low-Density Polyethylene (LLDPE) Using Fungal Mycelium (Part A): A Path Towards Sustainable Waste Management and Its Possible Economic Impacts

mycolabadmin

Researchers discovered that certain fungi, especially Schizophyllum commune, can effectively break down plastic waste called LLDPE through their natural enzymes. In laboratory tests, this fungus degraded plastic about 20 times faster than samples without fungal treatment over 30 days. This fungal approach is cheaper and more environmentally friendly than traditional methods like incineration or landfilling, and could help solve plastic pollution while creating jobs and using agricultural waste productively.

Unlocking the biodegradative potential of native white-rot fungi: a comparative study of fiberbank organic pollutant mycoremediation

mycolabadmin

Swedish researchers tested 26 types of white-rot fungi to clean up polluted sediments from old pulp and paper mills called fiberbanks. These contaminated sediments contain harmful chemicals and heavy metals. The study found that three fungal species, especially Diplomitoporus crustulinus, were excellent at breaking down pollutants and could tolerate the toxic environment, making them promising for environmental cleanup efforts.

Bibliometric analysis of global research on white rot fungi biotechnology for environmental application

mycolabadmin

White rot fungi are special mushrooms that can break down difficult-to-decompose pollutants in soil and water, offering a natural and cost-effective way to clean up environmental contamination. This research study analyzed over 3,900 scientific publications about using these fungi for environmental cleanup from 2003 to 2020. The analysis found that research on white rot fungi has grown significantly, with scientists from China and the USA leading the field, and identified three major application areas: treating biomass waste, removing dyes from wastewater, and cleaning polluted environments.

High Potential Decolourisation of Textile Dyes from Wastewater by Manganese Peroxidase Production of Newly Immobilised Trametes hirsuta PW17-41 and FTIR Analysis

mycolabadmin

This research shows that a fungus called Trametes hirsuta can effectively clean textile industry wastewater by breaking down colorful dyes that pollute the environment. The scientists attached the fungus to nylon sponges and optimized the treatment conditions to achieve over 95% color removal within just two days. The fungus produces special enzymes, particularly manganese peroxidase, that degrade the harmful dyes into safer substances, and the system can be reused repeatedly for continuous wastewater treatment.

Fungal Ligninolytic Enzymes and Their Application in Biomass Lignin Pretreatment

mycolabadmin

Scientists tested ten different types of fungi to see which ones could best break down lignin, a tough natural material found in plants. Four fungi species showed exceptional ability to produce special enzymes that decompose lignin. These findings could help develop new eco-friendly industrial processes for converting plant waste into useful products, potentially reducing reliance on chemical treatments and fossil fuels.

Degradation of High Concentrations of Anthracene Using White-Rot Wood-Inhabiting Fungi and Investigation of Enzyme Activities

mycolabadmin

Scientists in Iran discovered that certain wood-decay fungi, particularly Trametes versicolor mushrooms, can effectively break down anthracene, a toxic pollutant from oil and gas industries. These fungi produce special enzymes that degrade the harmful chemical into less toxic substances. In laboratory tests, these indigenous Iranian fungi successfully removed 20-64% of high-concentration anthracene over four weeks, showing promise for cleaning up contaminated sites.

Isolation of Fungi from a Textile Industry Effluent and the Screening of Their Potential to Degrade Industrial Dyes

mycolabadmin

Researchers isolated six fungal strains from textile factory wastewater and tested their ability to remove industrial dyes. Two types of fungi, Emmia latemarginata and Mucor circinelloides, successfully broke down different synthetic dyes commonly used in textile production. The fungi produced specific enzymes that degraded the dyes, particularly when exposed to the dye itself or plant materials like wheat straw. These findings suggest these fungi could potentially be used to clean up colored wastewater from textile industries.
