Hass Avocado (Persea americana Mill) Peel Extract Reveals Antimicrobial and Antioxidant Properties against Verticillium theobromae, Colletotrichum musae, and Aspergillus niger Pathogens Affecting Musa acuminata Colla Species, in Ecuador

mycolabadmin

Researchers tested whether avocado peel waste could help protect banana crops from fungal diseases. They extracted beneficial compounds from avocado peels and tested them against three harmful fungi that affect bananas. The results showed the extract worked best against one type of fungus and had good antioxidant properties, suggesting avocado peel could be a natural and sustainable way to protect banana crops.

Biocontrol of Seedborne Fungi on Small-Grained Cereals Using Bacillus halotolerans Strain B33

mycolabadmin

Researchers discovered that a bacterium called Bacillus halotolerans strain B33 can effectively prevent harmful fungi from damaging cereal seeds like wheat, barley, oats, and rye. When seeds were treated with this beneficial bacterium, it successfully eliminated or greatly reduced three dangerous fungal pathogens while also helping the seeds germinate better. This natural approach offers a promising environmentally-friendly alternative to chemical fungicides for protecting grain crops.

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.

Strains of Aureobasidium pullulans from Extreme Environments: New Potential Biocontrol Agents?

mycolabadmin

Researchers studied yeast strains collected from extreme environments like deserts and cold coastlines to find natural solutions for protecting fruit crops. They found that Aureobasidium pullulans, a black yeast that thrives in harsh conditions, can effectively control brown rot disease on peaches. The strains showed remarkable ability to survive extreme temperatures and pH levels, making them promising candidates for environmentally friendly crop protection that could help agriculture adapt to climate change.

Identification and Characterization of Five Previously Unrecorded Penicillium Species of Subgenus Aspergilloides Isolated in Korea

mycolabadmin

Researchers in Korea discovered one new Penicillium fungal species and four species that had not been previously recorded in the country. These fungi were found in freshwater and soil samples from five Korean provinces. By analyzing the fungi’s genetic material and physical characteristics, scientists confirmed their identities and added them to Korea’s catalog of fungal species. This research helps create a valuable collection of domestic fungal resources that may have future applications in agriculture and biotechnology.

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.

Introducing a global database of entomopathogenic fungi and their host associations

mycolabadmin

Scientists have created a global database called EntomoFun 1.0 that brings together information about fungi that naturally infect insects and other arthropods. The database contains nearly 1,800 records of different fungal species and the insects they infect, collected from scientific literature and museum specimens. This resource helps researchers understand where these fungi are found, which insects they target, and how they might be used for pest control or studied for their ecological importance.

Tracking of Tobacco Mosaic Virus in Taxonomically Different Plant Fungi

mycolabadmin

Scientists discovered that a common plant virus (tobacco mosaic virus) can infect and multiply inside certain fungal pathogens that harm crops. When the virus enters these fungi, the fungi activate their natural defense system to fight back. Interestingly, the virus doesn’t make the fungi more or less dangerous to plants. This discovery opens new possibilities for controlling harmful fungi using viruses as biological tools.

In vitro antifungal activity of plant extracts against fungal pathogens of onion (Allium cepa L.) and red pepper (Capsicum annum L.) in selected districts of Western Hararghe, Ethiopia

mycolabadmin

Onion and pepper farmers in Ethiopia lose significant crops to fungal diseases, and chemical fungicides are expensive and harmful. This study tested plant extracts from garlic, neem, and African wintersweet against disease-causing fungi. Acokanthera schimperi (African wintersweet) was most effective at stopping fungal growth, offering farmers an affordable, natural, and environmentally safe alternative to chemical fungicides.

Morpho-phylogenetic evidence reveals novel hyphomycetous fungi on medicinal plants in Southwestern China

mycolabadmin

Researchers in China discovered 12 new species of fungi living on medicinal plants, along with several previously unreported fungal occurrences. These fungi were identified using both microscopic examination and DNA analysis. Some of these fungi can produce harmful toxins, while others produce beneficial compounds that affect medicinal plant quality. This research helps us better understand the invisible fungal world living on the plants we use for medicine.
