WebThese data were fitted into experimental models that describe how pH varies within the mucus layer in the acid-secreting stomach. Results: It grew between pH 6 and 8, with optimal growth at pH 6. The bacterium had urease activity between pH 2.7 and 7.4, as evidenced by pH rises in bicarbonate-buffered solutions of urea. WebThe optimum growth pH is the most favorable pH for the growth of an organism. The lowest pH value that an organism can tolerate is called the minimum growth pH and the highest pH is the maximum growth pH.These values can cover a wide range, which is important for the preservation of food and to microorganisms’ survival in the stomach.
