Application of Fungus Enzymes in Spent Mushroom Composts from Edible Mushroom Cultivation for Phthalate Removal

mycolabadmin

This research shows that leftover mushroom growing material (spent compost) can be used to clean phthalates from wastewater. Phthalates are harmful chemicals found in plastics that can damage human health. Scientists tested four types of mushroom composts and found they all worked, with the best results removing 99% of certain phthalates. This provides an affordable, eco-friendly way to treat polluted 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.

The potential of fungi in the bioremediation of pharmaceutically active compounds: a comprehensive review

mycolabadmin

Pharmaceutical drugs that we take end up in our water systems because our bodies don’t fully process them. Fungi, especially types of mushrooms, have powerful enzymes that can break down these drug residues and clean contaminated water. Scientists are studying how to use these fungi in treatment systems to remove medications from hospital wastewater and drinking water sources.

Exploring the Potential of Fungal Biomass for Bisphenol A Removal in Aquatic Environments

mycolabadmin

Researchers discovered that mushroom fruiting bodies can effectively remove bisphenol A (BPA), a harmful plastic component, from water. Five mushroom species were particularly efficient, removing between 72-82% of BPA from solutions. The mushroom biomass works best at room temperature and neutral pH, can be reused multiple times after treatment with ethanol, and could potentially clean enormous volumes of contaminated water using small amounts of material.

Engineering bacterial biocatalysts for the degradation of phthalic acid esters

mycolabadmin

Phthalic acid esters (PAEs) are chemicals used to make plastics flexible that can leak into the environment and harm human health. Scientists are engineering bacteria with improved enzymes to break down PAEs more efficiently through a process called bioremediation. The review discusses how bacteria naturally degrade these pollutants and outlines strategies to make this process faster and more practical for cleaning contaminated environments.

Bacterial Cytochrome P450 Involvement in the Biodegradation of Fluorinated Pyrethroids

mycolabadmin

Scientists isolated a soil bacterium called Bacillus sp. MFK14 that can completely break down toxic fluorinated pesticides (specifically β-cyfluthrin and λ-cyhalothrin) within just two days. These pesticides are widely used in agriculture but persist in the environment and accumulate in living tissues, causing health problems. The study shows that special bacterial enzymes called cytochrome P450 play a key role in breaking these pesticides apart into less harmful products like fluoride ions. This discovery offers a promising natural solution for cleaning up pesticide-contaminated soil and water.

Biodegradation of the endocrine-disrupting compound bisphenol F by Sphingobium yanoikuyae DN12

mycolabadmin

Scientists discovered a bacterium called Sphingobium yanoikuyae that can break down bisphenol F (BPF), a toxic chemical used in plastics and coatings. The bacterium uses three special enzymes working together like a molecular assembly line to safely degrade BPF into harmless byproducts. This discovery could lead to better methods for cleaning up polluted water and soil contaminated with BPF and similar harmful chemicals.

Screening, identification, metabolic pathway of di-n-butyl phthalate degrading Priestia megaterium P-7 isolated from long-term film mulched cotton field soil in Xinjiang

mycolabadmin

This research identifies a special bacterium called Priestia megaterium P-7 that can efficiently break down di-n-butyl phthalate (DBP), a harmful plastic chemical that accumulates in cotton field soils. Scientists found that this bacterium can completely remove DBP from contaminated soil within 20 hours under optimal conditions. By studying the bacterium’s genes and metabolism, they discovered the specific enzymes and pathways it uses to degrade DBP into harmless compounds. This finding offers a practical biological solution for cleaning up contaminated agricultural soils, particularly in Xinjiang where plastic film mulching is widely used in cotton farming.

Oestrogen Detoxification Ability of White Rot Fungus Trametes hirsuta LE-BIN 072: Exoproteome and Transformation Product Profiling

mycolabadmin

A type of white rot fungus called Trametes hirsuta can effectively remove harmful oestrogen chemicals from water and soil. The fungus produces special enzymes that break down these hormones into less toxic compounds within just one day. This discovery suggests the fungus could be used as a natural treatment to clean up environmental contamination caused by oestrogens from human waste and pharmaceutical use.

Oestrogen Detoxification Ability of White Rot Fungus Trametes hirsuta LE-BIN 072: Exoproteome and Transformation Product Profiling

mycolabadmin

Scientists discovered that a white rot fungus called Trametes hirsuta can effectively remove harmful oestrogen hormones from water and soil. Within just one day, the fungus eliminated more than 90% of two common oestrogens (E1 and E2) that pollute our environment through pharmaceutical waste and animal farming. The fungus achieves this by producing special enzymes that couple oestrogen molecules together into larger, less harmful compounds that can be easily removed.
