Ambient ultraviolet radiation induces DNA damage in amphibian larvae under semi-natural conditions

mycolabadmin

Scientists studied whether natural sunlight damages the DNA of tadpoles by raising striped marsh frog larvae in outdoor pools with either normal or reduced sun exposure. They found that natural sunlight does cause measurable DNA damage in tadpoles, and some individual tadpoles were more affected than others. This research suggests that as UV radiation changes due to climate change, some amphibian populations may face greater risks to their survival and development.

Phytoremediation Potential of Heavy Metals Using Biochar and Accumulator Plants: A Sustainable Approach Towards Cleaner Environments

mycolabadmin

Researchers tested whether mixing coconut fiber biochar with contaminated mine soil could help plants called Sanvitalia procumbens clean up heavy metal pollution. The plants absorbed less toxic metals when grown in the biochar-amended soil, grew bigger, stayed healthier with more green coloring, and experienced less genetic damage. Using this natural byproduct from coconut processing as a soil amendment proved to be an effective and sustainable way to reduce heavy metal contamination risks to the environment and food chain.

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

mycolabadmin

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.

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

mycolabadmin

This study evaluated the safety of an enzyme called AMP deaminase that is used in food processing, particularly for making yeast products and mushroom extracts. Researchers tested the enzyme for genetic damage and toxicity using laboratory studies. The results showed the enzyme is safe for use in food manufacturing at the recommended levels, with a very large safety margin between the amounts used in food and amounts that might cause harm.

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

mycolabadmin

Scientists evaluated the safety of an enzyme called AMP deaminase used in food manufacturing, particularly for processing yeast and mushroom extracts. The enzyme is produced from bacteria and tests showed it does not cause genetic damage or harmful effects even at high doses. The actual exposure from eating foods made with this enzyme is extremely small, making it safe for consumer use in the approved applications.

Graphene nanomaterials: A new frontier in preventing respiratory fungal infections

mycolabadmin

Scientists are exploring nano-graphene oxide, a microscopic material made from graphene, as a new treatment for serious lung fungal infections. These tiny particles can kill fungal cells through multiple mechanisms and deliver antifungal drugs directly to infection sites while reducing harmful side effects. Researchers found that graphene oxide can be combined with existing antifungal medications to make them work better and even help overcome drug-resistant fungal infections.
