Impact of Volatile Organic Compounds on the Growth of Aspergillus flavus and Related Aflatoxin B1 Production: A Review

mycolabadmin

Aspergillus flavus is a dangerous fungus that produces aflatoxin B1, a poison that can cause serious diseases and survives even when food is heated. Scientists have discovered that certain smelly chemicals called volatile organic compounds, produced by other organisms or plants, can stop this fungus from growing and making its toxin. This research suggests these natural chemicals could be used to protect our crops and food supply from contamination.

In vitro and in vivo inhibitory effects and transcriptional reactions of graphene oxide on Verticillium dahliae

mycolabadmin

Scientists discovered that graphene oxide, a nanomaterial, can effectively kill or inhibit the growth of Verticillium dahliae, a harmful fungus that causes wilt disease in cotton and other crops. The graphene oxide works by damaging the fungus’s cell membranes and disrupting its ability to grow and spread. When applied to cotton plants infected with this fungus, graphene oxide treatment reduced disease symptoms and prevented the fungus from multiplying. This research suggests graphene oxide could become a valuable alternative to chemical fungicides for controlling this destructive plant disease.

Antifungal Volatile Organic Compounds from Talaromyces purpureogenus CEF642N: Insights from One Strain Many Compounds (OSMAC) Strategy for Controlling Verticillium dahliae in Cotton

mycolabadmin

Scientists discovered that a beneficial fungus called Talaromyces purpureogenus can produce powerful antifungal compounds that kill cotton wilt disease. By growing this fungus on different nutrient media, researchers identified two main antifungal compounds: 3-octanol and 2-octenal. These natural compounds completely or nearly completely stopped the growth of the cotton wilt pathogen in laboratory tests, offering a promising green alternative to chemical pesticides for protecting cotton crops.

In vitro and in vivo inhibitory effects and transcriptional reactions of graphene oxide on Verticillium dahliae

mycolabadmin

Graphene oxide, a nanomaterial derived from graphene, effectively inhibits the growth of Verticillium dahliae, a fungus that causes devastating wilt disease in cotton and many other plants. The study shows that graphene oxide damages the fungal cell membrane and disrupts key metabolic processes, preventing the fungus from growing and infecting plants. When applied to cotton plants, graphene oxide treatment significantly reduced wilt disease symptoms, suggesting it could be a promising alternative to chemical fungicides for controlling this important agricultural disease.

Bacillus velezensis LMY3-5 for the biocontrol of soft rot in kiwifruit: antifungal action and underlying mechanisms

mycolabadmin

Scientists discovered a beneficial bacteria called Bacillus velezensis that can effectively prevent soft rot disease in kiwifruit, which causes serious damage during storage. The bacteria works by producing natural antimicrobial compounds that damage the fungal pathogen’s cell walls and membranes, stopping it from growing. This biocontrol approach offers an environmentally friendly alternative to chemical fungicides, reducing pesticide residues while maintaining fruit quality and safety.

2-Nonanol produced by Bacillus velezensis EM-1: a new biocontrol agent against tobacco brown spot

mycolabadmin

Researchers discovered that a beneficial bacterium called Bacillus velezensis produces a natural compound called 2-nonanol that effectively kills the fungus causing brown spots on tobacco leaves. This compound works by disrupting the fungus’s ability to obtain energy and handle stress. Testing on tobacco leaves showed that 2-nonanol could significantly reduce disease development. This discovery offers a promising environmentally-friendly alternative to chemical fungicides for protecting tobacco crops.
