Manganese biomineralization occurred readily on metal surfaces in a natural freshwater environment. SEM demonstration of actual bacterial participation was challenging due to the rapidity of biofilm growth and typical microbe-mineral agglomeration. By optimizing cathodic polarization, we slowed down the process so effectually as to document biomineralization by rod-shaped rather than by filamentous bacteria which occurred more frequently at open circuit.

阴极极化使SEM可以说明天然生物膜中锰的生物矿化作用。
在天然淡水环境中,金属表面容易发生锰生物矿化作用。由于生物膜生长的快速性和典型的微生物-矿物质的聚集,SEM证明实际细菌的参与具有挑战性。通过优化阴极极化,我们有效地减慢了该过程,从而证明了棒状而不是丝状细菌的生物矿化作用是在开路时更频繁地发生。
