Biphasic Fermentation of Trapa bispinosa Shells by Ganoderma sinense and Characterization of Its Polysaccharides and Alcoholic Extract and Analysis of Their Bioactivity

mycolabadmin

This study investigated fermenting water chestnut shells with a medicinal mushroom called Ganoderma sinense to create a more potent health product. Under optimal fermentation conditions, the resulting material showed significantly improved immune-boosting and antioxidant properties when tested in laboratory cells. The fermentation process changed the structure of polysaccharides and increased beneficial compounds, potentially transforming agricultural waste into a valuable functional food or supplement.

A Zn2-Cys6 transcription factor, TgZct4, reprograms antioxidant activity in the fungus Trichoderma guizhouense to defend against oxidative stress

mycolabadmin

Trichoderma guizhouense is a fungus used to protect plants from harmful pathogens. Researchers discovered that a special protein called TgZct4 acts like a master switch that activates the fungus’s defense system against harmful reactive oxygen molecules. When the fungus encounters stress, TgZct4 turns on genes that produce protective enzymes called catalases and superoxide dismutases, helping the fungus survive. This discovery could help scientists create even more effective biological pest control products.

A Zn2-Cys6 transcription factor, TgZct4, reprograms antioxidant activity in the fungus Trichoderma guizhouense to defend against oxidative stress

mycolabadmin

A fungal biocontrol agent called Trichoderma guizhouense uses a special protein called TgZct4 to protect itself from harmful oxidative stress caused by hydrogen peroxide. When the fungus encounters this stress, TgZct4 activates a series of antioxidant enzymes that neutralize the damaging reactive oxygen species. This discovery helps explain how this beneficial fungus can survive and control plant diseases in harsh soil environments, potentially improving its use as an environmentally friendly alternative to chemical pesticides.

Enhanced Heat Resistance in Morchella eximia by Atmospheric and Room Temperature Plasma

mycolabadmin

Researchers used a special plasma technology to create heat-resistant strains of morel mushrooms that can thrive at higher temperatures. These mutant strains showed enhanced natural defense systems with more antioxidant enzymes and protective compounds. This breakthrough could help farmers grow more morels successfully despite rising temperatures from climate change, while maintaining their nutritional and medicinal benefits.
