Microorganisms, encompassing bacteria, viruses, fungi, and protists, play pivotal roles in marine ecosystems, influencing nutrient cycling, carbon sequestration, and overall ecological balance. Marine biotechnology allows to study and harness the genetic resources of marine organisms, potentially leading to the discovery of novel compounds and biochemical processes with applications in medicine, agriculture, and industry. In this course, you will understand both upstream and downstream processes in marine biotechnology as crucial steps for the efficient and sustainable development of products and applications.
