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.

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.

Hypoglycemic Effect of Pleurotus citrinopileatus and Hericium erinaceus Buccal Tablets on Diabetic Mice

mycolabadmin

Researchers created special tablets from two edible mushrooms (yellow oyster mushroom and lion’s mane) enriched with trace elements (chromium, zinc, germanium) to treat diabetes in mice. After three weeks of treatment, the high-dose tablets reduced blood sugar levels by 29%, improved cholesterol levels, boosted the body’s natural antioxidant defenses, and shifted the gut bacteria toward beneficial types that support metabolic health. These results suggest that mushroom-based treatments could potentially offer a natural way to help manage diabetes.

Modulating effects of Phellinus linteus polysaccharides on antioxidant capacity, immune function, intestinal function and microbiota in lipopolysaccharide-challenged broilers

mycolabadmin

Researchers studied how a medicinal mushroom extract called Phellinus linteus polysaccharides could help broiler chickens recover from immune stress caused by bacterial toxins. The supplement improved the chickens’ growth, reduced harmful inflammatory responses, and promoted beneficial gut bacteria while reducing harmful ones. The treatment strengthened the intestinal barrier and restored the chickens’ natural antioxidant defenses. This suggests the mushroom supplement could be a natural alternative to antibiotics for improving poultry health on farms.

Seasonal discrepancy of airborne fungal diversity and community structure in Lentinula edodes factory

mycolabadmin

This study examined how fungal spores in the air of shiitake mushroom factories change with the seasons and relate to a disease called shiitake artificial log rot disease (SLRD). Researchers found that when temperatures drop and humidity rises in autumn and winter, a harmful fungus called Trichoderma thrives in the air and causes more disease. By keeping the growing areas warmer, growers can significantly reduce disease occurrence and protect both their crops and workers’ health.

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

mycolabadmin

Researchers fed rainbow trout different diets made partly from mushroom stem waste and found that these ingredients beneficially changed the bacteria living in the fish’s gut. Different parts of the fish’s digestive system showed different changes in bacterial communities, suggesting these mushroom ingredients work in region-specific ways. The mushroom-based diets reduced harmful bacteria and increased beneficial ones, potentially improving fish health. This research shows how mushroom waste can be recycled into nutritious feed for farmed fish while promoting their health.

Characterization of fungal communities transmitted from sow to piglet

mycolabadmin

This study examined how fungi from mother pigs are passed to their newborn piglets. Researchers collected samples from sow feces, sow vaginas, and piglet feces and analyzed the fungal communities using genetic sequencing. They found that about 47% of the fungi in piglet feces came from the mother’s intestines, while a small amount came from the vagina, with the remainder from unknown environmental sources. The findings help us understand how maternal fungi help establish a healthy gut in newborns.

Analysis of the Differences in Rhizosphere Microbial Communities and Pathogen Adaptability in Chili Root Rot Disease Between Continuous Cropping and Rotation Cropping Systems

mycolabadmin

This study shows that rotating chili crops with cotton significantly improves soil health and reduces chili root rot disease compared to continuous chili cultivation. By changing crops, beneficial bacteria like Bacillus increase while disease-causing fungi like Fusarium decrease in the soil. The research identifies the main pathogens causing chili root rot and their growth preferences, providing farmers with a scientific basis for using crop rotation as a natural, sustainable alternative to chemical pesticides.

Effects of fermented rice husk powder on growth performance, rumen fermentation, and rumen microbial communities in fattening Hu sheep

mycolabadmin

Researchers tested whether fermented rice husk powder could improve the health and growth of sheep when used as feed. They found that sheep fed fermented rice husk grew faster and gained more weight than sheep fed unfermented rice husk. The fermented version also improved digestion and changed the beneficial bacteria in the sheep’s stomach in positive ways. This discovery could help farmers use agricultural waste more effectively as animal feed.

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.
