Thermoduric bacteria can survive and even grow at high temperatures, generally around 60-70°C. They are resistant to heat and are capable of withstanding pasteurization temperatures, making them a concern in dairy and food processing industries.

Psycothroph can grow at lower temperatures than mesophile Psycothroph minimum optimium maximum -5 to +5 ºC 25 to 30ºC 30 to 35ºC Mesophile minimum optimium maximum 5 to 15 ºC 30 to 40ºC 40 to 47ºC mesophile includes most of the Foodborne microorganisms in humans thermophile exist in geothermal environments, or under very hot temperatures under the ocean. requires a high temperature for optimum growth. minimum optimium maximum 40 to 14 ºC 55 to 75ºC 60 to 90ºC Thermoduric Are bacterias that survive the process of pasteurization, in form of spores.


What is thermoduric organism?

Thermoduric organisms are microorganisms that can survive high temperatures, typically those that exceed the pasteurization process, which usually involves heating to around 65-75°C (149-167°F). These organisms may not necessarily grow or reproduce at these temperatures, but they can withstand brief exposure to heat, making them resilient in various environments. Common examples include certain types of bacteria, such as some strains of Bacillus and Clostridium. Their presence is significant in food safety and quality, as they can survive processing methods and potentially cause spoilage or foodborne illness.


How would you sterilize a heat-sensitive growth medium containing thermoduric bacteria?

One option is to use chemical sterilization methods such as filtration using a sterilizing-grade filter or using ethylene oxide gas. These methods can effectively sterilize without subjecting the heat-sensitive growth medium to high temperatures that may compromise its quality or integrity. It is important to ensure proper ventilation and follow safety protocols when using chemical sterilization methods.


What organisms are not killed during pasteurization?

Some heat-resistant organisms like bacterial spores, thermoduric bacteria, and certain enzymes may survive pasteurization processes at typical temperatures and times. These organisms can affect the shelf life and safety of the product if not properly controlled through other means.


What effect does temperature have on the growth of bean plants?

Temperature affects the rate of growth in bean plants. Extreme temperatures can slow down or inhibit growth, while moderate temperatures within the plant's optimal range can promote healthy growth. High temperatures may cause stress and lead to wilting, while low temperatures can stunt growth.

What are the temperatures of thermoduric?

Thermoduric bacteria are those that survive the temperatures used in pasteurisation: 63ºC for 30 minutes or the equivalently lethal temperature.


What is the difference between thermophilic and thermoduric bacteria?

Thermophilic bacteria have growth temperatures that range from 45C to 85C, with an optimum temperature of about 60C. Thermoduric organisms can survive at extreme temperatures, e.g. pasteurization, but cannot grow.

What is thermophilic bacteria?

The thermoduric bacteria refers to the bacteria that can survive to varying extent. This type of bacteria is able to survive the pasteurization process.


How is grass growth and development influnced by temperature?

cold temperatures stall grass growth by freezing (or slowing the average energy of the molecules) of the plants water. Warm temperatures mean higher fluidity so easier nutrient transfer and faster growth.
