WebSuitable pH – Most bacteria reproduce best at a neutral pH level of 7. Acidic foods with a pH below 7, or alkaline foods with a pH above 7, may stop or slow down the rate of bacterial... WebThe 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. The basic pH also inhibits microbial growth.
