Synthesis of Acetobacter xylinum Bacterial Cellulose Aerogels and Their Effect on the Selected Properties

mycolabadmin

Scientists created a special lightweight foam-like material made from bacterial cellulose that could be used in wound dressings, insulation, and water filtration. The material was made sustainably using just tea, sugar, and bacteria—no harmful chemicals needed. Different freezing methods were tested to create the best possible structure, with liquid nitrogen freezing producing the most porous and uniform results. The material showed excellent insulation properties and is biodegradable, making it an environmentally friendly alternative to synthetic foams.

Effects of adding food ingredients rich in dietary fiber and polyphenols on the microstructure, texture, starch digestibility and functional properties of Chinese steamed bun

mycolabadmin

Researchers created an improved version of Chinese steamed bun by adding dragon fruit, kudzu root, and a medicinal mushroom called Hericium erinaceus. This new bun has much more fiber and antioxidants, and importantly, it causes much smaller increases in blood sugar after eating compared to traditional steamed buns. The study shows it can help promote beneficial gut bacteria and may be beneficial for people managing diabetes and metabolic health.

Characterization and Virulence of Metarhizium anisopliae (Hypocreales: Clavicipitaceae) Isolates from Ecologically Distinct Soils Against Spodoptera litura (Lepidoptera: Noctuidae)

mycolabadmin

This study identified five native fungal strains (Metarhizium anisopliae) from Taiwanese soils that can kill the tobacco caterpillar pest (Spodoptera litura). The most effective strain, PT-01, showed strong ability to infect and kill caterpillar larvae, particularly at early life stages. The research demonstrates that these fungi could be developed into environmentally-friendly pest control alternatives to chemical pesticides, protecting crops while maintaining ecosystem health.

Chromium-Tanned Leather and Microbial Consortia: Identification of Taxa With Biodegradation Potential and Chromium Tolerance

mycolabadmin

Leather waste from the tanning industry is difficult to break down and often ends up in landfills or incinerators. Scientists discovered that natural communities of bacteria found on decomposing leather can help break down chromium-tanned leather under simple nutrient conditions. These bacteria form protective biofilms and produce enzymes that gradually degrade the collagen in leather, offering a promising sustainable solution for managing leather waste.

Echoes of 1816: microbial footprints in heritage artifacts from Argentina’s museum of independence

mycolabadmin

Scientists studied bacteria living on historic artifacts at Argentina’s Independence Museum to understand how microbes damage precious heritage items. They found 49 different bacterial species on artifacts like 200-year-old photographs, wooden furniture, and textiles, discovering that each artifact hosts a unique microbial community. The study shows that understanding these bacteria is crucial for preserving cultural treasures and protecting museum workers from potential health risks caused by microbial exposure during artifact handling and conservation.

Clinical Isolate of Candida tropicalis from a Patient in North Carolina: Identification, Whole-Genome Sequence Analysis, and Anticandidal Activity of Ganoderma lucidum

mycolabadmin

Researchers in North Carolina identified a drug-resistant yeast infection (Candida tropicalis) from a hospital patient and tested whether extracts from reishi mushrooms (Ganoderma lucidum) could kill it. Using genetic analysis, they found mutations in the yeast that help it resist antifungal drugs. All three types of mushroom extracts tested successfully stopped the yeast’s growth and damaged its cells, suggesting that reishi mushrooms could be a promising natural treatment option for hard-to-treat candida infections.

Scanning electron microscopy of hyphal ectobiont bacteria within mycelial extracellular matrices

mycolabadmin

Researchers studied how bacteria (Bacillus subtilis) attach to mushroom fungi (Lion’s Mane/Hericium erinaceus) in liquid cultures. Using a special drying technique and electron microscopy, they were able to see tiny structures where bacteria stick to the fungal threads. These structures are made of slimy substances produced by the fungus and could potentially allow bacteria to influence the fungus’s electrical and physical properties.

Isolating and Identifying One Strain with Lead-Tolerant Fungus and Preliminary Study on Its Capability of Biosorption to Pb2+

mycolabadmin

Scientists discovered a fungal strain called Sarocladium that can effectively absorb lead from contaminated soil and water. This strain works best under specific conditions (25°C temperature and neutral pH) and can remove up to 37.75% of lead ions from highly contaminated solutions. The fungus captures lead through various chemical compounds on its cell surface, showing great promise as an inexpensive and environmentally friendly solution for cleaning up lead-polluted environments.

Histological Dissection of Fusarium-Banana Interaction Using a GFP-Tagged Subtropical Race 4 Strain of Fusarium oxysporum f. sp. cubense on Banana Cultivars with Differing Levels of Resistance

mycolabadmin

Researchers used fluorescently-labeled fungal strains to visualize how banana wilt disease spreads inside banana plants. They found that resistant banana varieties can slow down the fungus by forming blockages (called tyloses) in their water-conducting vessels, though the fungus can still initially enter the plant. The study showed that the rhizome, an underground stem-like structure, is the key location where resistant plants successfully contain the fungus, which helps explain why some banana varieties are naturally more resistant to this devastating disease.

Physicochemical, microbiological, and microstructural changes in germinated wheat grain

mycolabadmin

When wheat grains are exposed to moisture and warm conditions, they begin to sprout, which damages their quality and usefulness. This research studied how different moisture, temperature, and time conditions affect sprouted wheat grain. Scientists found that sprouting significantly changes the grain’s structure, reducing its starch content and increasing microbial contamination. The findings suggest that sprouted wheat can be processed into useful products if grown under carefully controlled conditions.
