Explore the intricate world of cell structures and biosorption processes in this comprehensive 26-minute video lecture. Delve into the differences between prokaryotic and eukaryotic cell walls, examining bacterial, archaeal, plant, animal, algal, and fungal cell structures. Learn about various bacterial excretions, including extracellular polymeric substances (EPS), sheaths, and S-layers. Understand the concept of cell surface charge and its role in biosorption. Discover the mechanisms of passive and active biosorption, including how microbes detoxify their environment by immobilizing toxic metals. Gain insights into the importance of these processes in geobiology and their applications in bioremediation.
