Surface Display of Multiple Metal-Binding Domains in Deinococcus radiodurans Alleviates Cadmium and Lead Toxicity in Rice

Scientists created genetically engineered bacteria (Deinococcus radiodurans) that can grab and absorb harmful heavy metals like cadmium and lead from soil and water. When these specially designed bacteria colonize rice plant roots, they protect the plants from metal toxicity by removing metals from the environment and boosting the plant’s natural defense systems. This approach could help make rice safer to eat by preventing dangerous metal accumulation in crops grown in contaminated areas.

Bioremediation of Landfill Leachate with Fungi: Autochthonous vs. Allochthonous Strains

This research compared two approaches to cleaning landfill leachate using fungi: using fungi naturally found in the polluted water versus using well-studied fungi species from laboratory collections. Scientists tested how effectively these fungi could remove color and toxins from contaminated wastewater. The study found that both types of fungi worked reasonably well, but through different mechanisms—some fungi absorbed the pollutants while others chemically broke them down using special enzymes.

Transcriptome analysis of Ochratoxin A (OTA) producing Aspergillus westerdijkiae fc-1 under varying osmotic pressure

This research studied how salt concentration affects the production of ochratoxin A, a toxic substance produced by the fungus Aspergillus westerdijkiae that contaminates foods like coffee and grapes. Using advanced genetic analysis, scientists found that moderate salt levels (20 g/L) increase the fungus’s ability to produce this toxin by affecting specific genes. The findings help explain why OTA contamination is more common in salty foods like cured meats and suggest new ways to prevent this contamination and protect food safety.

Insights into metabolic and pharmacological profiling of Aspergillus ficuum through bioinformatics and experimental techniques

Researchers studied a fungus called Aspergillus ficuum and found it contains compounds with potential medicinal benefits. The fungal extract showed strong antibacterial activity against disease-causing bacteria and reduced inflammation in mice. Additionally, the extract had antioxidant properties that help fight harmful free radicals, with no toxic effects observed, making it a promising candidate for developing new medications.

Updated safety evaluation of the food enzyme AMP deaminase from the non‐genetically modified Streptomyces murinus strain AE‐DNTS

Scientists evaluated the safety of AMP deaminase, an enzyme used in food processing for yeast and mushroom extract production. The enzyme is produced from a naturally occurring bacterium and is intended to help break down adenosine monophosphate during food manufacturing. Through extensive testing including genetic mutation tests and animal studies, researchers found no safety concerns when used at recommended levels in food processing. The amount of enzyme that consumers might ingest through food is far below levels that could cause any adverse effects.

Knowledge, attitude, and practice on mushroom poisoning among residents of Jilin province

This study examined what residents of Jilin Province know, believe, and do about mushroom poisoning. Researchers found that most people have only moderate knowledge about the dangers of wild mushrooms, with significant gaps in understanding toxicity. While people generally have positive attitudes toward safety, many still engage in risky practices like consuming wild mushrooms. The research highlights the need for better public education, especially in rural areas where access to medical help and health information may be limited.
