Yes Each microbial species is characterized by minimum and maximum pH Values within which the growth is possible. The optimum pH value is that value at which the growth rate is most rapid. There could be many exceptions to the general statement as regards pH preferences, they can be stated as under:
1. Most bacteria have pH optimum near 7 and min and max pH values are 5 and 9
2. Most fungi prefer pH between 1-3 with optimum pH near 5
3. Most Blue green algae have pH optimum higher than 7
4. Most protozoa are able to grow between pH 5-8 and optimum is 7

" One way of affecting the growth of bacteria is by changing its pH level. Bacteria, like all living organisms, prefer a certain pH balance. Over millions of years, some bacteria have developed mechanisms to adapt to pH imbalances. "
Different microorganisms often require distinct environments, with varied temperature, levels of oxygen, light and acidity or pH level. Some microbes grow faster in environments with extremely low pH values. These are called acidophiles, because of their preference for acidic environments. Although most microorganisms requires neutral pH values to have optimum growth, alkaliphilic microorganisms prefer low-acidity or high pH environment.
