Fig. 4From: Experimental and visual research on the microbial induced carbonate precipitation by Pseudomonas aeruginosa Biofilm traps precipitated fine calcite particles from bulk flow: a–c are under deposition mode and d is under suspension mode (control). a and b are xy planes of the same biofilm colony but at different depths. a is near bottom and b is near top. Mineral particle size distributions of a and b are plotted in e Back to article page
