Microbes play key role in carcinogenesis

At any given time, over 10 trillion microbes call our guts their home. From breaking down nutrients in our food to strengthening our immunity against pathogens, these microbes play an essential role in how we interact with the world. This includes – as shown in a new study by EMBL researchers and collaborators at the University of Split, Croatia – the way the body responds to carcinogens and develops cancer.

Unraveling the microbial dynamics of spontaneous fermentation

Shibazuke is a traditional Japanese eggplant pickle produced by the process of fermentation using lactic acid bacteria (LAB). LAB which is commonly present in vegetables causes the spontaneous fermentation of vegetables, resulting in the distinctive acidic flavor of pickles. While LAB is beneficial, other species of bacteria and microbes that may be present in the food source can affect the food quality and safety. Advancements in the areas of food technology and nutrition have allowed the large-scale fermentation of pickles via industrial fermenters, where conditions that affect fermentation like temperature, pH-acid levels, and salt content are closely monitored.
