Effect of temperature on bacterial growth rate Effect of Temperature on the growth of E coli Bacteria grow over a Optimum temperature 30 of growth(37.C) range of temperatures; they do not reproduce below the =20 minimum growth temperature nor above the maximum growth Minimum 1.0 temperature Maximum temperature. Within the of growth 8°C temperature of growth temperature growth range 48°C there is an optimum growth 30 4050 temperature at which bacterial °F405060708090100110120 reproduction is fastest TemperatureBacteria grow over a range of temperatures; they do not reproduce below the minimum growth temperature nor above the maximum growth temperature. Within the temperature growth range there is an optimum growth temperature at which bacterial reproduction is fastest. Effect of temperature on bacterial growth rate
