Contactless Ammonia Mapping for Concentric Colony Pattern of Proteus mirabilis
Journal of Chemical Engineering of Japan
A simple and easy method for the simultaneous monitoring of colony shape and ammonia productivity of swarming bacteria such as Proteus mirabilis should become increasingly important for the characterization of the bacteria. A contactless mapping method of ammonia concentration produced by Proteus mirabilis colony is proposed using an array of pH indicator solution and a digital still camera, by using a PC display as a backlight. Brightness of the indicator solution was quanti ed from thedoi:10.1252/jcej.17we157 fatcat:jphmchouqzbn3havqquy2nltsm
