WebFeb 10, 2024 · Most bacteria are neutrophiles and grow best at near-neutral pH (center curve). Acidophiles have optimal growth at pH values near 3 and alkaliphiles have optimal growth at pH values above 9. At the other end of the spectrum are alkaliphiles, microorganisms that grow best at pH between 8.0 and 10.5.
