Web1) Classify microbes into five groups on the basis of the preferred temperature range. 2) Identify how and why the pH of culture media is controlled. 3) Explain the importance of osmotic pressure to microbial growth. 4) Name a use for each of the four elements (carbon, nitrogen, sulfur, and phosphorus) needed in large amounts for microbial growth. WebThe growth medium controls the pH of the culture and buffers the cells in culture against changes in the pH. Usually, this buffering is achieved by including an organic (e.g., HEPES) or CO 2-bicarbonate based buffer.Because the pH of the medium is dependent on the delicate balance of dissolved carbon dioxide (CO 2) and bicarbonate (HCO 3 –), changes in the …
