Discovering secrets of the ocean: application note on marine microbiology
October 26, 2018
Deep down in the ocean, between and under the layers of the water, the secrets of the life itself are hidden, invisible to the naked eye. Studying marine microbes, which cover more than 70% of the earth and represent the world's largest ecosystem, can reveal information about ocean's chemistry and climate, and maybe even bring us closer to understanding how the life originated on our planet.
Studying something as tiny as marine microbes can be extremely challenging. Microscopy proves to be a great tool for examining physiological and metabolic states of individual cells. Two types of imaging can be extremely effective. Fluorescence microscopy helps to image the function and provides information regarding metabolism of the organism. On the other hand, it is impossible to get information about ultrastructural composition of the sample. In order to identify cells and different communities of microbes a high resolution imaging, performed by electron microscopy, is required.
