The course will aim to provide an introduction to geomicrobiology and to describe how microbial communities have influenced biogeochemical and mineralogical processes through geologic time. Topics will include microbial properties and diversity; microbial metabolism, cell surface reactivity and metal sorption; biomineralization; microbial weathering; microbial zonation and early microbial life. This course will also include a practical laboratory part; students will perform experiments on microbial zonation and biomineralization.
