The acidity or alkalinity of an environment influences microbial growth. The optimal pH for growth of bacterial with clinical significance usually occurs between?

The correct answer is - 6.5 to 7.5 pH.

Explanation:

The proper acidity or alaklinity or pH of an environment affect the growth of the microbes. The most suitable pH value for the most of the microbes are between 6.5 to 7 pH.

Most bacteria influences bacterial growth positively around neutral pHvale which is 6.5 to 7.5. However, some present in acidic nature called acidophiles as they can tolerate pH value of 1.

Thus, the correct answer is - 6.5 to 7.5 pH.
