The role of Micro-biome engineering in enhancing Food safety and quality

mycolabadmin

Microbiome engineering uses advanced biotechnology to strategically modify helpful bacteria in food to make it safer and higher quality. By using tools like CRISPR gene editing and engineering beneficial probiotics, scientists can prevent food spoilage, reduce harmful bacteria, improve nutrition, and create better-tasting foods. These innovations could reduce reliance on synthetic preservatives and chemicals while addressing global food safety challenges and helping combat malnutrition.

New insights into the stress response mechanisms of stress-resistant Listeria monocytogenes via multi-omics and cell morphological changes

mycolabadmin

Researchers studied how a dangerous food-poisoning bacterium called Listeria monocytogenes survives in harsh conditions like cold temperatures, acidic environments, and salty food products. Using advanced molecular analysis techniques, they identified specific genes and proteins that help the bacteria survive these stressful conditions. They also observed that the bacteria changed shape when exposed to stress, becoming elongated and bumpy. This research helps food safety experts better understand and combat this persistent food contaminant.
