Ph of culture media
WebbMost bacteria grow between pH 6.5 and 7.5. When bacteria are cultured in the laboratory, they often produce acids that eventually interfere with their own growth. To Neutralize the acids and maintain the proper pH, chemical buffers are included in the growth medium. WebbAdjust the pH to 0.2 and 0.3 units below the desired final working pH by slowly adding, with stirring, 1 N NaOH or 1 N HCl. The pH may rise 0.1 to 0.3 units upon filtration. Adjust the final volume with distilled water. Process the medium immediately into sterile containers by membrane filtration using a positive-pressure system.
