Local pH measurement at wet mineral-bacteria/air interface
Résumé
Scanning electrochemical microscopy (SECM) was used to measure local pH in the thin water film located at the mineral-Rahnella aquatilis RA1/air interface. The method allowed differentiating acidification kinetics in conditions of natural soils and sediments where water can form film around mineral. (C) 2014 Elsevier B.V. All rights reserved.
