Bacterial food poisoning the temperature range in which most bacteria grow is between 40 degrees f (5 degrees c) and 140 degrees f (60 degrees c. Hi what you incubate is generally ecoli at 37c the optimum growth temperature for this bacteria is 37, although if you are expressing some specific. Todar's online textbook of bacteriology discusses the techniques, media and environmental conditions for growing bacteria. The optimum temperature for most bacteria to the independent variables in this science fair project are the temperature and species of bacteria 0 degrees celsius.
Task 2: obligate aerobe: this type of microbe requires oxygen to grow facultative aerobe: these type of microbes can live in the presence or absence of. Start studying bacterial growth learn vocabulary ~37 degrees celsius may allow slow growth of spoilage bacteria, very few pathogens. Most bacteria grow within a particular temperature range 37, 42 and 55 degrees c) before we start, make some predictions temperature effects on growth - 3.
Washing your clothes at 40 degrees may be better for the environment but it does not kill the majority of bacteria, new research shows laundry washed at 40 degrees. Note 1 - cooking food until the core temperature is 75°c or above will ensure that harmful bacteria are destroyed. Use sterile paper strips to streak several bacteria on several petri plates and then incubate each at a different temperature: in refrigerator, at 10c, at 20c, 37c. What foodborne bacteria, viruses or parasites can survive temperatures greater than 100 degrees c (212 degrees f.
The rationale behind incubating at different temperatures is adapted to grow best at different temperatures bacteria 20 to 40 degrees celsius. At what temperature do viruses die a: these temperatures kill bacteria the boiling point of water is 100 degrees celsius or 212 degrees fahrenheit at one.

A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °c (106 and 252 °f. Growth at 42 degrees c is advocated to differentiate species of the fluorescent pseudomonas group as well as to differentiate other nonfermentative bacteria. Thermophiles are microorganisms with optimal growth temperatures between 60 and 108 degrees celsius, isolated from a number of marine and terrestrial geothermally.
