Effect of Cordyceps militaris Residue and Lactiplantibacillus plantarum on Fermentation Quality and Bacterial Community of Alfalfa Silage

mycolabadmin

This research shows that waste leftover from growing medicinal mushrooms (Cordyceps militaris) can be effectively reused as an additive to improve the quality of stored animal feed (alfalfa silage). When the mushroom residue was added, it boosted beneficial bacteria that produce lactic acid, which preserved the feed better and reduced ammonia content. This finding offers an environmentally friendly way to reduce waste while simultaneously improving livestock feed quality.

Microbial communities associated with the black morel Morchella sextelata cultivated in greenhouses

mycolabadmin

This study examined the tiny organisms living on and around cultivated black morel mushrooms grown in greenhouses in China. Researchers found that four main types of bacteria consistently live on morel fruiting bodies: Pedobacter, Pseudomonas, Stenotrophomonas, and Flavobacterium. The bacteria and fungi in the soil surrounding morels appear to be important for the mushrooms’ growth and development, with different microbial communities found on different parts of the mushroom.

The interplay between the formation of Chinese cordyceps and the characteristics of soil properties and microbial network

mycolabadmin

This research examined how soil properties and bacteria change during the growth of Chinese cordyceps, a valuable medicinal fungus found on the Qinghai-Tibet Plateau. Scientists discovered that the most critical stage occurs when the fungus infects and consumes the host larvae, during which soil becomes less acidic, loses nutrients, and experiences significant changes in bacterial communities. The findings show that specific bacteria like Pseudomonas and Dyella help the cordyceps grow by breaking down chitin from the larvae’s exoskeleton. Understanding these interactions can help improve artificial production of this expensive medicinal fungus.

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.
