Based on optimal growth pH, microbes can be separated into three groups: acidophiles grow best at pH < 5, neutrophiles grow optimally at pH between 5 and 9, and alkaliphiles grow fastest above pH 9 ( Horikoshi, 1999; Baker-Austin and Dopson, 2007 ). WebpH. Bacteria are sensitive to various pH range. The bacterial species that grow at a pH range above or below the preferred value would not survive. But, bacteria at optimum pH show the best growth in nearly neutral pH, i.e. 6.5-7.5. The acidic pH usually restricts microbial growth, and it is frequently used in food preservation methods. curing fibromyalgia
