Thermophilic Bacteria vs. Mesophilic Bacteria
Main DifferenceThe main difference between Thermophilic Bacteria and Mesophilic Bacteria is that Thermophilic Bacteria survive and usually live at relatively high temperatures, whereas Mesophilic Bacteria survive and live in low and moderate temperatures.
Difference Between Thermophilic Bacteria and Mesophilic Bacteria
Thermophilic Bacteria vs. Mesophilic Bacteria
The primary type of extremophiles that prosper and grow well at relatively high temperatures is known as the thermophilic bacteria; on the contrary, referred to as a type of bacteria that thrives and grows well at nearly moderate temperatures and low temperatures is known as the mesophilic bacteria.
Thermophilic Bacteria vs. Mesophilic Bacteria
The optimum temperature for the growth of the thermophilic bacteria is considered as the 50 °C; on the flip side of the thermophilic bacteria, the optimum temperature for the thriving of the mesophilic bacteria is approximately is the 37 °C which is the optimum body temperature of humans.
Thermophilic Bacteria vs. Mesophilic Bacteria
45-122 °C is considered as the growth temperature for the thermophilic bacteria in which they thrive; at the same time, the growth temperature for mesophilic bacteria are considered as the 20-45 °C in which they grow well and is known as the moderate temperature for their growth.
Thermophilic Bacteria vs. Mesophilic Bacteria
The thermophilic bacteria consist of specific enzymes which only become functional at high temperatures; on the flip side, the mesophilic bacteria do not release any such enzymes which are functional at high temperature, while they only release enzymes which are operational at moderate temperature.
Thermophilic Bacteria vs. Mesophilic Bacteria
The formation of heat-stable DNA polymerases which are useful in the process of PCR is the main application of thermophilic bacteria, in contrast to that, the formation of yogurt, cheese, wine, and beer is the main application of mesophilic bacteria.
Thermophilic Bacteria vs. Mesophilic Bacteria
The thermophilic bacteria are not considered pathogens because they cannot grow at body temperatures of humans. In contrast, the mesophilic bacteria are considered pathogens because they can grow at body temperatures of humans.
Thermophilic Bacteria vs. Mesophilic Bacteria
Some examples of thermophilic bacteria are Synechococcus, Thermococcus litoralis, Hermus aquaticus, Calothrix; on the contrary, some general examples of mesophilic bacteria are Streptococcus pyrogenes, Listeria monocytogenes, Staphylococcus auresu, etc.

Thermophilic Bacteria vs. Mesophilic Bacteria
Thermophilic bacteria are considered as the kind of extremophiles which grow well at comparatively high temperatures. On the other hand, the mesophilic bacteria are considered as the type of bacteria that thrives neatly at low and moderate temperatures. The temperature at which thermophilic bacteria thrive is at 45-122 °C; on the contrary, the moderate temperature at which mesophilic bacteria grow well is at 20-45 °C.
50 °C is known as the optimum temperature for the thermophilic bacteria; on the flip side, 37 °C is known to be the optimum temperature for the mesophilic bacteria. The enzymes which are released by the thermophilic bacteria are usually functional at high temperatures; in contrast to thermophilic bacteria, the mesophilic bacteria do not release enzymes that are operational at high temperatures; instead, they release enzymes which are only functional at low temperature.
The thermophilic bacteria usually cannot grow at body temperatures, so they are not considered as pathogens; on the other hand, the mesophilic bacteria are known as pathogens because they can grow at body temperatures. The application of thermophilic bacteria generally is that it forms the heat-stable DNA polymerases, which are then being used in PCR; on the flip side, the primary application of mesophilic bacteria is that they are mostly used in the formation of yogurt, beer, cheese, and wine.

What are Thermophilic Bacteria?
The bacteria which grow well comparatively at a high temperature, which is nearly equal to 45-122 °C, is known as the thermophilic bacteria. The habitat of thermophilic bacteria is usually a variety of oceans, marine, and some terrestrial habitats. Some living spots of thermophilic bacteria are also the hot springs that are present in deep-sea hydrothermal vents, Yellowstone National Park, and decomposing plant material, for example, fertilizer marshlands and manure.
The thermophilic bacteria contain many molecular and some biochemical approaches to overcome the damaging effects of the very high temperature. 50 °C is known as the optimum temperature for the thermophilic bacteria. The thermophilic bacteria usually cannot grow at body temperatures, so they are not considered as pathogens.
The application of thermophilic bacteria generally is that it forms the heat-stable DNA polymerases, which are then being used in PCR. Some examples of thermophilic bacteria are Synechococcus, Thermococcus litoralis, Hermus aquaticus, Calothrix, etc.
What are Mesophilic Bacteria?
The bacteria which grow well only at moderate temperatures or at a temperature, which not too cold or nor too hot, nearly at 20-45 °C, is known as the mesophilic bacteria. 37 °C is known to be the optimum temperature for the mesophilic bacteria, which is the optimum body temperature of humans. The mesophilic bacteria are more sensitive to changes occur in their temperate, as they cannot synthesize protein at very low temperature.
The mesophilic bacteria are known as pathogens because they can grow at body temperatures, so the bacteria which is present in the human microbiome, and along with that, the human pathogenic bacteria are known as mesophiles. The mesophilic bacteria do not release enzymes which are operational at high temperatures; instead, they release enzymes which are only functional at low temperature.
The most crucial application of mesophilic bacteria is that they are mostly used in the formation of yogurt, in the fermentation of beer, and wine, cheese, and as well as these are also the habitats of mesophilic bacteria. Some general examples of mesophilic bacteria are Streptococcus pyrogenes, Listeria monocytogenes, Staphylococcus auresu, etc.
ConclusionThe above discussion concludes that the thermophilic bacteria needs high temperature for their survival; in contrast, the mesophilic bacteria requires moderate temperature for their growth.
