Draft genome sequence of three Glaciozyma watsonii strains isolated from near the Syowa station area, East Antarctica

mycolabadmin

Scientists have sequenced the genetic code of three strains of a special cold-loving yeast called Glaciozyma watsonii found in East Antarctica. This yeast can grow in extremely cold conditions, even at temperatures below freezing, which is remarkable. Understanding its genome may help scientists develop new medicines and discover enzymes that work in cold conditions.

Effect of Dietary Insect Meal and Grape Marc Inclusion on Flavor Volatile Compounds and Shell Color of Juvenile Abalone Haliotis iris

mycolabadmin

Researchers tested whether using insect meal and grape marc as sustainable alternatives to fish meal in abalone feed would affect meat flavor and shell color. The study found that grape marc reduced unpleasant off-flavors in the meat while insect meal had minimal effect on flavor. Neither ingredient significantly changed shell color. These findings suggest these sustainable ingredients could improve both environmental impact and product quality in abalone farming.

Harmonizing Nature, Education, Engineering and Creativity: An Interdisciplinary Educational Exploration of Engineered Living Materials, Artistry and Sustainability Using Collaborative Mycelium Brick Construction

mycolabadmin

This study shows how middle-school students can learn science, engineering, and art together by growing and building with mycelium, a fungal material that can replace plastic and other harmful materials. Students designed shapes, created molds, cultivated living mycelium bricks under sterile conditions, and assembled them into an artistic structure. The hands-on experience helped students develop practical skills like precise measuring and 3D thinking while learning about sustainability and nature’s cycles.

Fungal alkaloids mediate defense against bruchid beetles in field populations of an arborescent ipomoea

mycolabadmin

Morning glory trees (Ipomoea murucoides) form beneficial relationships with fungal partners that live inside their tissues and produce toxic compounds called alkaloids. These alkaloids accumulate in the tree’s seeds and protect them from beetle damage. Trees hosting the common fungal partner Ceramothyrium produce more of the protective alkaloid swainsonine and suffer less seed damage than those with a different fungal partner, demonstrating how this natural partnership helps the plant defend its offspring.

Misconception of Schizophyllum commune strain 20R-7-F01 origin from subseafloor sediments over 20 million years old

mycolabadmin

Researchers questioned whether a fungus found in ancient ocean sediments 2 km below the seafloor actually came from 20 million years ago or was modern contamination. By analyzing DNA repetitive sequences in different fungal populations, they discovered the strain was genetically almost identical to modern fungi from Asia, not ancient at all. The extreme conditions in the deep sediments would make it impossible for fungi to survive or exchange genes for millions of years, proving the fungus came from surface contamination during drilling rather than ancient times.

Silver Chloride Precipitation-limiting Factor for Accurate Silver Determination in Ag-accumulating Mushrooms After Nitric Acid Digestion

mycolabadmin

This research addresses a critical problem in measuring silver content in certain mushrooms, particularly silver-accumulating Amanita species. Scientists discovered that standard laboratory digestion procedures using nitric acid can cause silver to precipitate as silver chloride, making it invisible to measurement instruments and leading to false low results. The study demonstrates that neutron activation analysis is more accurate for measuring silver in these mushrooms, or alternatively, specialized multi-step digestion procedures can dissolve the precipitated silver chloride to obtain accurate measurements.

Two new species of Entoloma subg. Cyanula sect. Asprella (Entolomataceae, Agaricales) from subtropical regions of China

mycolabadmin

Scientists have identified two new mushroom species in China belonging to the genus Entoloma. These small blue and magenta mushrooms, named E. qingluan and E. zilin, were discovered in subtropical forests of Fujian and Zhejiang provinces. Using microscopic examination and genetic analysis, the researchers confirmed these were previously unknown species and provided detailed descriptions for scientific identification and classification.

Diversity of Lignicolous Freshwater Fungi from Yuanjiang River in Yunnan (China), with the Description of Four New Species

mycolabadmin

Scientists studied freshwater fungi living on decaying wood in the Yuanjiang River in southwestern China. They collected samples and used both microscopy and genetic analysis to identify nine fungal species, four of which were previously unknown to science. This research helps us understand the diversity of fungi in freshwater ecosystems and their role in breaking down wood materials in nature.

Exploring Mitochondrial Heterogeneity and Evolutionary Dynamics in Thelephora ganbajun through Population Genomics

mycolabadmin

Scientists studied the mitochondrial DNA of an edible mushroom species found only in Yunnan, China, called Thelephora ganbajun. They discovered that these mushrooms have unusual genetic diversity in their mitochondria, with multiple different versions of certain genes coexisting within individual organisms. This genetic flexibility appears to be an adaptation that helps the species survive in diverse environmental conditions and prevents the accumulation of harmful mutations.

Effect of Antibacterial Peptide Microsphere Coating on the Microbial and Physicochemical Characteristics of Tricholoma matsutake during Cold Storage

mycolabadmin

This research demonstrates that coating expensive wild matsutake mushrooms with special antimicrobial peptides wrapped in tiny polymer microspheres can keep them fresh for up to 20 days instead of just 1-3 days. The coating works by protecting mushrooms from water loss, microbial spoilage, and browning while preserving their texture and nutritional quality. This edible coating technology could help mushroom producers sell their products over longer distances and extend availability of these prized wild mushrooms.
