Enhanced biodegradation of fluorinated pharmaceutical by Aspergillus flavus and Cunninghamella elegans biofilms: kinetics and mechanisms

mycolabadmin

Researchers discovered that two types of fungi, Aspergillus flavus and Cunninghamella elegans, can effectively break down common prescription drugs like fluoxetine, ciprofloxacin, and atorvastatin in wastewater. When grown as biofilms on foam carriers, these fungi removed over 90% of the pharmaceuticals in just a few days. This is an important finding because conventional wastewater treatment doesn’t effectively remove these medications, which can harm aquatic ecosystems.

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

mycolabadmin

This research shows that oyster mushrooms (Pleurotus ostreatus) can effectively remove Remazol Brilliant Blue R dye from contaminated water. The mushroom pellets remove the dye through a combination of absorbing it on their surface and breaking it down with special enzymes called laccases and peroxidases. The study achieved 98.5% dye removal, suggesting this mushroom could be used to treat industrial wastewater from textile factories.

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.

A new type of calcium-rich biochars derived from spent mushroom substrates and their efficient adsorption properties for cationic dyes

mycolabadmin

Researchers developed a low-cost material called biochar from leftover mushroom growing substrates that can effectively remove harmful dyes from wastewater. By heating these spent mushroom substrates to high temperatures, they created a porous material rich in calcium that works as a powerful filter. This biochar can be used multiple times and doesn’t require expensive chemical treatments, making it practical for large-scale wastewater cleanup in textile and related industries.

Conversion of Soluble Compounds in Distillery Wastewater into Fungal Biomass and Metabolites Using Australian Ganoderma Isolates

mycolabadmin

Researchers discovered that Ganoderma mushroom mycelium can clean up rum distillery wastewater while producing edible, protein-rich fungal biomass. The mycelium successfully removed harmful compounds from the wastewater and accumulated bioactive compounds with health benefits. This dual-benefit approach transforms an environmental waste problem into a valuable food ingredient, offering a sustainable and economical solution for the distillery industry.

Mycoremediation of azole antifungal agents using in vitro cultures of Lentinula edodes

mycolabadmin

This research shows that shiitake mushrooms (Lentinula edodes) can help clean up antifungal medications that contaminate water and soil. When the mushroom mycelium was exposed to two common antifungal drugs used in creams and treatments, it absorbed and broke down these compounds. The mushrooms degraded about one-third of the drugs by targeting their chemical structure, particularly the imidazole ring. This suggests mushrooms could be used as a natural, cost-effective solution for removing pharmaceutical pollution from the environment.

Enhanced biodegradation of fluorinated pharmaceutical by Aspergillus flavus and Cunninghamella elegans biofilms: kinetics and mechanisms

mycolabadmin

This study demonstrates that two types of fungi, Aspergillus flavus and Cunninghamella elegans, can effectively remove persistent pharmaceutical pollution from wastewater when grown as biofilms on foam carriers. The fungi achieved removal rates of 92-98% for three common medications (atorvastatin, ciprofloxacin, and fluoxetine) much faster than previously reported methods. Unlike traditional fungal treatments that depend on lignin, these fungi can work in diverse environments, making them practical for wastewater treatment plants and offering a sustainable biological solution to pharmaceutical pollution.

Nicotine Degradation by Trametes versicolor: Insights from Diverse Environmental Stressors and Wastewater Medium

mycolabadmin

This study shows that a common mushroom fungus called Trametes versicolor can effectively break down and remove nicotine from wastewater. The research found that the fungus works best at room temperature and slightly acidic conditions, particularly when grown in wastewater-like media. The findings suggest this fungal approach could become an environmentally friendly way to clean up nicotine pollution in water systems.

Optimising Chlorella vulgaris bioflocculation by Aspergillus Niger pellets and their application in wastewater treatment and lipid production

mycolabadmin

This research demonstrates an innovative approach to cleaning wastewater using a combination of algae and fungal pellets. The scientists optimized conditions for growing Aspergillus niger fungi as compact pellets that can efficiently trap and harvest microscopic algae cells. When these fungal-algae pellets were used to treat wastewater, they removed over 90% of harmful nutrients like ammonium and phosphate, making it a cost-effective and environmentally friendly alternative to traditional water treatment methods.

Hydrothermal liquefaction aqueous phase mycoremediation to increase inorganic nitrogen availability

mycolabadmin

This research shows that a common mushroom fungus called Trametes versicolor can clean up wastewater produced during the conversion of food waste into biofuel. The fungus transforms hard-to-use nitrogen compounds in the waste into forms that plants can absorb. After three days of treatment, the nitrogen that plants can use increased dramatically. When bacteria known for converting ammonia to nitrate were added to the fungal treatment, the results improved even more, suggesting this waste could eventually be recycled as a fertilizer for growing plants in water-based farming systems.
