The Antimicrobial Extract Derived from Pseudomonas sp. HP-1 for Inhibition of Aspergillus flavus Growth and Prolongation of Maize Seed Storage

mycolabadmin

Researchers discovered that a beneficial bacterium called Pseudomonas sp. HP-1 can produce a natural compound that effectively prevents mold contamination in stored maize seeds. The extract from this bacterium showed strong antifungal activity against Aspergillus flavus, a major cause of aflatoxin contamination in grain storage. The main protective compound was identified as phenazinecarboxylic acid, which works by damaging the cell membranes of fungal cells. This finding offers a promising eco-friendly alternative to synthetic chemical fungicides for protecting stored crops.

Real-time CO2 monitoring for early detection of grain spoilage and mycotoxin contamination

This research shows that monitoring carbon dioxide levels in stored grain is a better way to detect dangerous mold contamination than measuring temperature alone. Scientists tested this approach in both small laboratory containers and larger industrial grain silos over nine months, finding that CO2 levels rise rapidly when grain gets wet and fungal contamination begins. This early warning system could help food producers quickly take action to prevent spoilage and contamination with harmful toxins that can make people sick.

Exploring Fungal Communication Mechanisms in the Rhizosphere Microbiome for a Sustainable Green Agriculture

Fungi in soil communicate with each other and plants through chemical signals, forming protective layers called biofilms that help them cooperate and survive. These fungal communication networks can be either beneficial, helping plants grow and fight diseases, or harmful, causing crop infections and producing toxins. By better understanding how fungi talk to each other, scientists can develop natural ways to improve agriculture and clean up polluted soils without using harmful chemicals.

Antagonistic Potential of Agro-Industrial Byproduct–Derived Lactic Acid Bacteria Against Mycotoxigenic Aspergillus flavus and Fusarium verticillioides

Researchers discovered that certain lactic acid bacteria found in food waste products can effectively prevent the growth of harmful fungi and block the production of dangerous mycotoxins. These bacteria work through multiple mechanisms including acidification and production of protective compounds. The findings suggest these natural bacteria could be used as safe, sustainable alternatives to chemical fungicides in food preservation and safety.

Recent Knowledge in the Application of Saccharomyces cerevisiae in Aquaculture: A Bibliometric and Narrative Review

This comprehensive review examines how baker’s yeast (Saccharomyces cerevisiae) is being used as a probiotic supplement in fish farming and aquaculture. The research shows that adding this yeast to fish feed improves growth rates, helps fish fight off diseases, and creates healthier gut bacteria in aquatic animals. Scientists worldwide are increasingly studying this natural alternative to antibiotics, with studies demonstrating benefits across various fish species including tilapia, trout, and catfish, making it an important tool for sustainable and healthier aquaculture practices.

Isolation and Identification of Aspergillus spp. from Rotted Walnuts and Inhibition Mechanism of Aspergillus flavus via Cinnamon Essential Oil

mycolabadmin

Researchers collected rotted walnuts from storage in Shanxi, China and identified five types of Aspergillus fungi contaminating them, with Aspergillus flavus being the most common. They tested cinnamon essential oil as a natural antifungal treatment and found it effectively stopped fungal growth by damaging the fungi’s cell membranes and causing oxidative stress. This research suggests cinnamon essential oil could be used as a safe, natural alternative to chemical fungicides for preserving walnuts and other foods from fungal spoilage.

Impact of Various Essential Oils on the Development of Pathogens of the Fusarium Genus and on Health and Germination Parameters of Winter Wheat and Maize

mycolabadmin

Researchers tested four plant-based essential oils as natural alternatives to chemical fungicides for protecting wheat and maize seeds from harmful Fusarium fungi. Thyme oil proved most effective at preventing fungal infections and seedling disease, performing as well as synthetic fungicides. However, thyme oil at higher doses harmed seed germination and plant growth, suggesting careful dose selection is needed for practical use. The findings indicate essential oils could replace chemical pesticides while maintaining crop safety, though different oils must be tested for various crops.

Impact of Various Essential Oils on the Development of Pathogens of the Fusarium Genus and on Health and Germination Parameters of Winter Wheat and Maize

Researchers tested whether essential oils from common herbs like thyme, sage, and cumin could protect wheat and corn seeds from fungal diseases. Thyme oil worked best at killing the harmful fungi, but it also slowed down seed sprouting. The study suggests these natural oils could replace chemical fungicides in farming, though farmers need to carefully choose which oil and how much to use.

Modelling the Combined Effects of Oxalic Acid, Water Activity, and pH on the Growth and Mycotoxin Production of Aspergillus spp. in a Dried Fig System

mycolabadmin

This research develops computer models to predict when dangerous molds grow on dried figs and produce toxins. Scientists tested how wet the figs are, their acidity, and a natural plant compound called oxalic acid affect the growth of two common toxic molds. The study found that drier figs are much safer from toxin production, and while oxalic acid alone isn’t a strong mold-fighter, it can help when combined with other conditions. These models can help the fig industry prevent contamination and keep dried figs safe for consumers.
