The incubator maintains optimal temperature, humidity and other conditions such as the CO 2 and oxygen content of the atmosphere inside. Incubators are essential for much experimental work in cell biology , microbiology and molecular biology and are used to culture both bacterial and eukaryotic cells.
Geobacillus stearothermophilus (previously Bacillus stearothermophilus) [1] [2] is a rod-shaped, Gram-positive bacterium and a member of the phylum Bacillota.The bacterium is a thermophile and is widely distributed in soil, hot springs, ocean sediment, and is a cause of spoilage in food products.
Thermus thermophilus is a Gram-negative bacterium used in a range of biotechnological applications, including as a model organism for genetic manipulation, structural genomics, and systems biology. The bacterium is extremely thermophilic , with an optimal growth temperature of about 65 °C (149 °F).
The phase-change incubator is a low-cost, low-maintenance incubator that tests for microorganisms in water supplies. It uses small balls containing a chemical compound that, when heated and then kept insulated, will stay at 37 °C (approx. 99 °F) for 24 hours.
Antibiotics can have the adverse effect of destroying beneficial bacteria and causing harmful bacteria to multiply, which invokes AAD. Adults who ate yogurt containing S. thermophilus while being treated with antibiotics had lower rates of AAD than the control group (12.4% vs. 23.7%). [23]
A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, with an optimum growth range from 20 to 45 °C (68 to 113 °F). [1] The optimum growth temperature for these organisms is 37 °C (about 99 °F). [2] The term is mainly applied to microorganisms.
The sealed anaerobic jar is then incubated at a desired temperature to allow growth of the bacteria. In the above figure for example, the incubation occurred at 100 °F (38 °C). A colorless indicator strip provides proof that the anaerobic conditions were met and the agar plates can now be observed for bacterial growth.
The optimal growth temperature range for B. cereus is 30-40 °C. [29] At 30 °C (86 °F), a population of B. cereus can double in as little as 20 minutes or as long as 3 hours, depending on the food product.
