Error is different for almost every acid The error may be as high as 0.5 pH There is no clear theoretical explanation and no clear relationship to pH glass compositions WebMost of them stop growing at a pH of 5.0. Some microorganisms can go as low as 4.6 and even down to 4.4. Historically, a pH of 4.6 was considered to be the lower growth limit, but portions of the food code were changed when it was discovered that some problematic microbes can grow in pH levels as low as 4.2.
