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.
摘要
对总共23种测试固体培养基在不同厌氧培养时间后表面pH值的变化进行了测量。未接种平板的表面pH值变化很小，但接种脆弱拟杆菌的平板pH值显著下降，在某些测试培养基中降至pH 5。讨论了控制固体培养基表面pH值的问题，并考虑了可能的控制方法。
