From: Inducing mineral precipitation in groundwater by addition of phosphate
Representative SEM images of solids collected from the four treatments during the course of the experiment: (a) treatment AC after 24 hours, (b) treatment HC after 72 hours, (c) treatment AC after 7 days, (d) treatment OA after 7 days, (e) treatment LC after 7 days, and (f) treatment HC after 7 days. Arrows in (e) and (f) indicate where precipitate appears to occur on bacterial cells. Scale bar for all images is 3 micrometers.
