Effect of the growth of anaerobic bacteria on the surface pH of solid media

Effect of the growth of anaerobic bacteria on the surface pH of solid media

B Watt et al. J Clin Pathol. 1985 May.

Abstract

Changes in surface pH occurring after varying periods of anaerobic incubation were measured for a total of 23 test solid media. There was little change in the surface pH of uninoculated plates, but plates inoculated with Bacteriodes fragilis showed a striking fall in pH, to pH 5 in the case of some of the test media. The problems of controlling the surface pH of solid media are discussed and possible methods of control are considered.
