Airborne Fungal Spore Diversity Assessment Using Culture-Dependent and Metabarcoding Approaches in Bat-Inhabited Natural and Anthropogenic Roosts in Portugal

mycolabadmin

Researchers studied fungal diversity in bat caves across Portugal using two methods: growing fungi in labs and analyzing DNA from air samples. They found over 280 different types of fungi, with some being common decomposers and others potentially harmful to human health. The study revealed that bat activity and human visits significantly influence which fungi live in caves, highlighting the importance of protecting these unique underground ecosystems.

Comparative Analysis of the Mycobiomes of Two Terrestrial Isopods, Armadillidium vulgare and Spherillo obscurus

mycolabadmin

This study compared the fungal communities living on two species of pill bugs found on Korean islands. Researchers discovered that one species, Spherillo obscurus, harbors a much more diverse and varied fungal community than the other species, Armadillidium vulgare, which is dominated by a single fungal genus. Interestingly, the type of isopod species was far more important in determining which fungi lived on them than the geographic location where they were found.

Mycobiome analyses of critically ill COVID-19 patients

mycolabadmin

This study examined fungal infections in severely ill COVID-19 patients treated in intensive care units across Europe. Researchers found that a dangerous mold called Aspergillus fumigatus was more common in patients who died and less common in those treated with azole antifungal drugs. The findings suggest that giving antifungal medications to critically ill COVID-19 patients when they arrive at the hospital might help prevent fungal-related deaths.

Characterization of fungal communities transmitted from sow to piglet

mycolabadmin

This study examines how fungal communities pass from mother pigs to their newborns. Researchers collected samples from sow feces, sow vagina, and newborn piglet feces and analyzed their fungal composition. The findings show that newborn piglets acquire most of their gut fungi from their mother’s intestinal tract rather than her vagina. Understanding this transmission helps us learn how the healthy microbiota that protects young animals develops.

What Quality Suffices for Nanopore Metabarcoding? Reconsidering Methodology and Ectomycorrhizae in Decaying Fagus sylvatica Bark as Case Study

mycolabadmin

This study shows that Nanopore DNA sequencing can reliably identify fungi in decaying wood. Researchers developed guidelines for quality filtering of Nanopore data to ensure accurate identification of fungal species. They found that specific mycorrhizal fungi, particularly Laccaria amethystina and Tomentella sublilacina, colonize young beech trees growing on decaying logs and help them obtain nutrients.

Mushroom stem-based diets elicit region-specific shifts in rainbow trout gut microbiota

mycolabadmin

Researchers fed rainbow trout different diets containing mushroom stem waste from grocery stores for six weeks and studied how the mushroom ingredients affected the fish’s gut bacteria. They found that mushroom diets promoted beneficial bacteria in different parts of the fish’s intestine without harming the fish. This research shows that mushroom waste can be recycled into healthy fish feed while supporting the fish’s digestive health and supporting a more circular food system.

Pneumocystis jirovecii is a potential pivotal ecological driver contributing to shifts in microbial equilibrium during the early-life lower airway microbiome assembly

mycolabadmin

Researchers studied how bacteria and fungi colonize infant lungs during the first year of life by examining lung tissue from autopsied infants. They found that the lung microbiome undergoes major changes between 2-4 months of age, and that a common fungal infection called Pneumocystis plays a key role in reshaping this microbial community. These early-life changes could have lasting impacts on children’s respiratory health later in life.

Sustainable Recycling of Mushroom Residue as an Effective Substitute for Cotton Hull Waste in Volvariella volvacea Cultivation: Evidence from Physicochemical and Microbiome Analyses

mycolabadmin

This research shows that mushroom waste left over from growing mushrooms can be successfully recycled as a growing medium for straw mushrooms, similar to the traditional cotton hull waste currently used. The recycled mushroom residue produces mushrooms of equivalent quality and quantity but costs much less to purchase. By analyzing the microscopic bacterial communities in the compost, scientists found that different bacteria help break down the organic matter in both types of substrates, supporting efficient mushroom growth.

The Expanding Truffle Environment: A Study of the Microbial Dynamics in the Old Productive Site and the New Tuber magnatum Picco Habitat

mycolabadmin

Researchers studied how microbial communities (fungi and bacteria) develop in expanding white truffle forests compared to established productive forests in Tuscany, Italy. Over two years, they found that new forest areas have more diverse and unstable microbial communities with rapid colonization by various fungi, while older forests show more stable communities dominated by truffle-associated fungi. The study reveals how forest management practices, like selective cutting, influence the balance between fungi that break down plant material and those that form beneficial relationships with tree roots, suggesting that understanding these microbial dynamics is key to successfully expanding truffle cultivation.

Insights into microbiome-triterpenoid correlation in Poria cocos via comparative analysis of sclerotial and soil microenvironments

mycolabadmin

This study explores how the medicinal mushroom Poria cocos creates its own special microbial environment inside its sclerotium (the part used in medicine). Researchers found that the mushroom selectively enriches certain bacteria and fungi while maintaining lower overall microbial diversity compared to surrounding soil. The study reveals that specific microbes like Burkholderia and Scytalidium are positively associated with the production of pachymic acid, the mushroom’s key medicinal compound with anti-tumor and anti-inflammatory properties.
