How does different temperatures produce different microbial growth rates?

Microbes grow in warm temperatures. But there is a limit, they need an optimum temperature to grow best.
Bacteria have an optimal temperature for growth, yes, but the temperature varies with the microbe.
Bacteria are split into classes based on where the optimal growth temp. falls. The edges of the groupings are fuzzy, but the approx. ranges are:
1. Extreme psychophiles (or psychotrophs) -- below -5oC
2. Psychophiles (or psychotrophs) -- -5oC to 25oC
3. Mesophiles-- 25oC to 45oC
4. Thermophiles-- 45oC to 70oC
5. Extreme thermophiles-- above 70oC
There is overlap and different sources will have different ranges, but these categories define bacterial habitat from Arctic ice to inside hydrothermal vents of sea floor volcanos. Food spoiles in the refrigerator because there are bacteria that grow at those tempreatures.

∙ 9y agoDifferent types of microbes thrive in different types of temperatures. Bacteria, for example, fall into two categories: psychrophiles can grow at temperatures around 20°C some below while thermophiles tend to grow at temperatures 45°C and above. Pathogens, on the other hand, generally thrive in the range of 5°C and 63°C.

What is microbiostatic?
Inhibits microbial growth
What is Exponential growth phase of microbial growth?
When the bacteria double at a constant rate
What physical method is used to control microbial growth works via the mechanism of protein denature?
Heat is the physical method used to control microbial growth via the mechanism of protein denaturation. By exposing microbes to high temperatures, the heat disrupts and denatures the proteins in their cells, leading to their inactivation and ultimately killing them. This method is commonly used in processes such as pasteurization and autoclaving to sterilize equipment and destroy harmful microorganisms.
Can there more less or the same amount of growth on the expose plates when incubated at two different temperatures?
It is possible but not likely. The warmer temperature normally favors more rapid growth. Some bacteria or molds prefer cooler temperatures.
What inhibits microbial growth at nonoptimal?
Both acidity and alkalinity can inhibit microbial growth. Acid is often used in food as a preservative to prevent microbial growth.
Why do vacuum sealed produce swell up?
Generally vacuum-sealed foods swell due to microbial growth in the food.
Definition of microbial growth?
microbial growth is the multiplying by dividing of micro-organisms such as bacteria, algae, fungi etc.
What is microbiostatic?
Inhibits microbial growth
What has the author Allen I Laskin written?
Allen I. Laskin has written: 'Advances in Applied Microbiology' 'Growth and metabolism' -- subject(s): Microbial growth, Microbial metabolism 'Nucleic acid biosynthesis' -- subject(s): Nucleic acids, Synthesis 'Microbial metabolism, genetics, and immunology' -- subject(s): Immunology, Microbial genetics, Microbial metabolism 'Microbial products' -- subject(s): Microbial products, Tables
What is Exponential growth phase of microbial growth?
When the bacteria double at a constant rate
A surface chemical that prevents microbial growth is?
interferon
Do microbial growth refers to a population and not to an individual cell?
A cell
Why would homemade soup fizz and smell?
It would fizz and smell because of microbial growth. The soup is spoiling. Yeast and some bacteria produce gas as waste products of their metabolism.
Define oligodynamic action?
its the microbial growth inhibition by heavy metal ions

Example of microbial contamination?
Microbial contamination is the introduction and growth of harmful microorganisms in foods and water, causing food borne illness and even death. Some examples of microbial contamination include botulism, salmonella, and mold.
