Project report on using scanning electron microscopy (SEM) to investigate microbe mineral interfaces on wetland soil

Created using ChatSlide

This research explores microbe-mineral interfaces in wetland soils, focusing on the Calumet wetland with fluctuating hydrology. Using SEM and EDS, soil cores under varying redox conditions are analyzed to study microbial and mineral dynamics. Initial findings show sparse microbes and limited aggregation; later stages reveal filament increases and diatom presence, with mineral chemistry linked to microbial colonization. Enhanced interface imaging and gas flux studies highlight energy dynamics...
