MRC - Laboratories


There are many reasons life and living organisms are fascinating. Our laboratory deals primarily with research of the tiniest creatures – microorganisms and their extraordinary properties. These microscopic single-cell organisms often work as perfect chemical factories capable of a wide variety of unique processes. Each and every cell can produce a broad range of various chemicals and biomaterials it needs for its survival. Under certain circumstances, it can even stockpile these products. Our objective is to develop methods and technologies of microbial production of industrial substances such as biomaterials, enzymes, vitamins, pigments and other natural molecules. We also develop ways of using these chemicals, especially in the fields of pharmacy, healthcare, food industry and cosmetics. At the same time, we investigate potential effects of various materials and bioproducts on living cells of all types (e.g. human, microbial, etc.).
