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

mycolabadmin

Two types of fungi, Aspergillus flavus and Cunninghamella elegans, can effectively break down pharmaceutical pollutants commonly found in wastewater, such as antidepressants and antibiotics. When grown as biofilms on foam carriers, these fungi removed over 90% of the target pharmaceuticals very quickly. The fungi accomplish this primarily through enzymatic breakdown rather than absorption, making them promising candidates for cleaning wastewater at treatment plants.

Fungal Innovations—Advancing Sustainable Materials, Genetics, and Applications for Industry

mycolabadmin

Fungi can be engineered to create sustainable, eco-friendly materials for construction, textiles, and packaging. Using advanced genetic tools and controlled growing conditions, scientists can customize fungal materials to have specific properties like flexibility or rigidity. These mycelium-based materials are biodegradable, renewable, and offer promising alternatives to traditional synthetic and conventional materials, helping reduce our dependence on petroleum-based products.

Comparative transcriptome analysis reveals the role of sugar signaling in response to high temperature stress in Armillaria gallica

mycolabadmin

Scientists studied how a fungus called Armillaria gallica responds to high heat, which is important because this fungus forms a partnership with a valuable medicinal plant called Gastrodia elata. They compared a heat-tolerant fungal strain with a heat-sensitive one and found that the heat-tolerant strain increases sugar accumulation and activates specific genes that help it survive hot conditions. Adding sucrose to the fungus’s growth medium helped it tolerate heat better, suggesting that sugar plays a key role in heat stress protection.

Mushroom and cereal β-D-glucan solid state NMR and FTIR datasets

mycolabadmin

This research provides a large database of spectroscopic measurements from β-D-glucans extracted from various mushrooms and cereal grains. The data includes detailed chemical fingerprints obtained through two analytical techniques (NMR and infrared spectroscopy) that can help researchers understand the structure and properties of these beneficial compounds. The dataset is freely available for other scientists to analyze and use for developing new methods or understanding how different mushroom and cereal sources vary in their chemical composition.

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.

Occurrence and function of enzymes for lignocellulose degradation in commercial Agaricus bisporus cultivation

mycolabadmin

White button mushrooms grow on compost made from straw and manure through carefully controlled phases. The mushroom uses specific enzymes to break down tough plant materials, especially lignin during the growing mycelium stage, which helps make nutrients available for mushroom formation. Understanding these enzymatic processes could help mushroom farmers improve their production by developing better mushroom strains that degrade plant materials more efficiently.

Experimental Assessment of Multiple Properties of Mycelium-Based Composites with Sewage Sludge and Bagasse

mycolabadmin

Researchers developed a sustainable building material by growing mushroom mycelium (fungal threads) on sewage sludge and bagasse waste. The resulting composites were lightweight, strong enough for highway construction, and environmentally friendly compared to conventional materials made from expanded polystyrene or cement. This innovation offers a promising way to reduce both construction waste and municipal sewage sludge disposal challenges.

Selection and validation of reference genes for RT-qPCR in ophiocordyceps sinensis under different experimental conditions

mycolabadmin

Scientists studied the Chinese caterpillar mushroom (Ophiocordyceps sinensis) to find the best genes to use as reference points when measuring other gene activity. They tested sixteen potential reference genes under various stress conditions and growth stages using a technique called RT-qPCR. They found that two specific genes (18S rRNA and beta-Tubulin) were the most reliable to use as standards, which will help researchers accurately study how this medicinal mushroom responds to different conditions.

Biocomposites Based on Mould Biomass and Waste Fibres for the Production of Agrotextiles: Technology Development, Material Characterization, and Agricultural Application

mycolabadmin

Researchers developed a new eco-friendly material made from mould mycelium combined with waste plant fibres that can be used as a substitute for synthetic agricultural textiles. The material successfully grows in about 5 days, can be completely biodegraded in soil within 10 days, and helps seeds germinate faster. This innovation supports sustainable farming by eliminating microplastic pollution from traditional synthetic crop covers while providing better properties than many conventional alternatives.

Integrated Transcriptomics and Metabolomics Provide Insight into Degeneration-Related Molecular Mechanisms of Morchella importuna During Repeated Subculturing

mycolabadmin

This study explains why morel mushroom strains weaken when repeatedly grown in laboratories. Researchers found that degenerated strains lose the ability to produce protective compounds called flavonoids, which act as natural antioxidants. By understanding these molecular changes, the researchers suggest that avoiding frequent subculturing and using preservation methods like low-temperature storage could help keep morel strains healthy and productive.
