Does pH decrease after bacterial growth in LB or other unbuffered media?

30 October 2013 1 3K Report

Is this true for pseudomonas aeruginosa? or other bacteria?

Short answer, yes...metabolic byproducts secreated into the medium can not only lower pH but increase it as well...it just depends on factors such as what bug is growing, what it is growing in, length of time in culture, etc.
