Bacterial growth is governed by factors such as temperature, pH, salt concentration, nutrient and oxygen. The optimum temperature for most bacteria to survive and grow ranges from 25 degrees Celsius to 40 degrees Celsius, and the optimum pH ranges from 6 to 8.bservation. Bacteria that were exposed to temperatures of 60 degrees Celsius and 100 degrees Celsius were observed not to have any growth when transferred to the Petri dishes, whereas bacteria exposed to -78 degrees Celsius and 0 degrees Celsius were observed to have a significant amount of growth.
Many factors affect bacterial growth but the most important ones are: 1  Water -- Bacteria need water to dissolve the food they use for energy and growth. 2  Water allows the food to get into the cells, is used for the many chemical reactions necessary for life and growth, and allows waste products to escape.escribe the conditions favorable to the growth of bacteria in food.
