  • How bacteria create the smells in our world
    Bacteria create various smells in our world, from pleasant aromas like freshly baked bread to the less appealing ones like body odour. As bacteria produce volatile organic compounds as part of their metabolism, these contribute to the scents we encounter in our environment, food and even on our bodies. Learn about smelly examples such as […]
  • How your immune system battles harmful bacteria every day
    Your immune system is constantly patrolling your body, ensuring that it stays clean and free of disease. Every single day, every hour, every minute, pathogens are pouring in, attempting to call your body their home and cause disease. But your immune system has specialised drones who bring the fight directly to the intruders. These drones […]
  • Microbial fermentation impacts our food, industry and health
    Microbial fermentation is a metabolic process that impacts our food, health and many industries. Microbes degrade substrates and convert them into fermentation products, with different species producing unique products. This process is essential in food preservation, creating diverse and complex flavours in fermented foods. Additionally, the microbes involved in fermentation can have health benefits when […]
