Sulfur and Nitrogen Cycles

This lecture covers the sulfur and nitrogen cycles, focusing on the biological and chemical processes involved. It discusses the diversity of sulfur-reducing bacteria, the impact of sulfate-reducing bacteria on steel structures, and the key sulfur compounds. The lecture also explores the role of sulfur and nitrogen in biogeochemistry, including the microbial components of the sulfur cycle and the processes of sulfur oxidation and reduction. Additionally, it delves into the environmental implications of sulfur and nitrogen cycling, such as acid mine drainage and bioleaching of copper ore.
