Root zone microbial communities of Artemisia ordosica Krasch. at different successional stages in Mu US Sandy Land: a metagenomic perspective with culturomics insights

mycolabadmin

Researchers studied the bacteria and fungi living around the roots of a desert plant called Artemisia ordosica that helps prevent sand dunes from spreading in China. By analyzing DNA and growing microbes in the lab, they found different communities of microorganisms at different stages of sand dune recovery. Key beneficial microbes like Bacillus and Penicillium were identified, which may help the plant survive in harsh, nutrient-poor sandy soils.

Development of a consortium-based microbial agent beneficial to composting of distilled grain waste for Pleurotus ostreatus cultivation

mycolabadmin

Scientists developed a special mix of five beneficial bacteria found in grain waste composting to speed up the process of preparing grain waste as growing substrate for oyster mushrooms. This microbial treatment made the composting hotter and faster, allowing oyster mushroom roots to grow quicker on the substrate. While the final mushroom harvest was similar in quantity, using this microbial treatment allowed farmers to harvest mushrooms about a week earlier. This method offers a practical way to recycle grain waste into valuable mushroom crops.

Mycobiome of Stool, Blood, Thrombus and Vessel Wall in Abdominal Aortic Aneurysm Patients

mycolabadmin

This study examined fungal communities in blood, stool, and damaged aorta tissues from patients with abdominal aortic aneurysm, a serious condition where the main blood vessel weakens and bulges. Researchers found that healthy blood vessels contain protective fungi called Tomentella, while damaged vessels have high levels of harmful fungi called Malassezia. Interestingly, the fungi found in damaged vessel walls may not come directly from the gut, suggesting they originate from other body parts like the mouth or skin. These findings suggest that controlling fungal communities with targeted antifungal treatments might help prevent or slow aneurysm development.
