Lab 4 is used for microbiological studies, where microbes are cultivated, isolated, enumerated and stored. The effects of biotechnological processes are also studied, such as the separation of biological products and test of surface tension reduction from biosurfactants. Related chemical analyses such as nutrient content can be made with the help of a UV-vis spectrometer.
