Metagenomic assembled dataset of potentially polyethylene terephthalate-degrading microcosms enriched from seawater, cow dung, and landfill soil

mycolabadmin

Scientists have created a database of 99 microbial genomes collected from seawater, cow manure, and landfill soil that can potentially break down polyethylene terephthalate (PET), the plastic used in bottles and clothing. These microorganisms were grown in laboratory experiments for 180 days using PET as their only food source. The research provides valuable information about which bacteria and archaea might help solve plastic pollution problems through natural biodegradation.

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.

The Effect of Pseudomonas putida on the Microbial Community in Casing Soil for the Cultivation of Morchella sextelata

mycolabadmin

Morel mushrooms are prized edible fungi, but growing them repeatedly in the same soil causes problems because toxic ethylene gas builds up and the soil microbiome becomes unbalanced. Scientists found that a beneficial soil bacterium called Pseudomonas putida can break down the ethylene precursor and improve the soil microbial community, making morels grow better and faster. This natural approach using microbial inoculation offers a practical solution to help farmers overcome these continuous cropping challenges.

Biochemical, physicochemical property and archaea community characteristics in casing soil of cultivating Stropharia rugosoannulata

This study examined how soil changes during the five growth stages of king stropharia mushrooms. Researchers measured soil properties, enzyme activity, and identified archaeal microorganisms present in the soil. They found that soil chemistry and microbial communities changed predictably during mushroom development, with certain beneficial archaea being more active at specific growth stages. These findings can help farmers optimize growing conditions and reduce contamination problems in mushroom production.

Genetic sequencing of the airborne fungal spectrum and air quality at a public hospital in Mexico City

mycolabadmin

Researchers tested the air inside and outside a Mexico City hospital to identify harmful fungi that could make patients sick. Using two different sampling methods, they found 27 different fungal species, including dangerous ones like Aspergillus fumigatus that cause serious infections especially in people with weakened immune systems. The study shows that hospitals need better air monitoring systems to protect vulnerable patients from these airborne infections.

Disseminated subcutaneous sporotrichosis in an immunocompetent patient: A case report and a systematic literature review

mycolabadmin

A 74-year-old man developed painful red masses on his arm and hand after being stuck by a tree branch. Tests identified the infection was caused by a fungus called Sporothrix schenckii. Despite having a normal immune system, the infection had spread across his arm in an unusual pattern. Treatment with an antifungal medication called itraconazole completely healed the lesions within four months without any scarring.

Characterization of the gut mycobiome in patients with non-alcoholic fatty liver disease and correlations with serum metabolome

mycolabadmin

This research reveals that the types of fungi living in our gut are linked to fatty liver disease in ways we didn’t fully understand before. While researchers have long studied bacteria in our gut, they largely ignored fungi, which turns out to play an important role too. The study found that certain fungal species are more common in people with fatty liver disease, and these fungi influence the metabolites (chemical compounds) in the blood that affect liver health. By combining information about fungi, bacteria, and blood chemistry, scientists developed a test that could identify fatty liver disease with 77% accuracy, suggesting that looking at gut fungi could help doctors diagnose and treat this common liver condition.

Ancient Microbiomes as Mirrored by DNA Extracted From Century-Old Herbarium Plants and Associated Soil

mycolabadmin

Scientists extracted and analyzed ancient DNA from plant roots and soil samples stored in herbarium collections for over 120 years. The DNA showed typical signs of age and preserved microbial communities that originally lived in the soil around these plants. By comparing these ancient microbial communities to modern ones, researchers found that herbarium storage preserved the original characteristics of soil microbiomes, making these museum specimens valuable for studying how farming practices have changed soil ecosystems over time.
