What are the 6 conditions that affect the growth of microorganisms?
FAT TOM is a mnemonic device used in the food service industry to describe the six favorable conditions required for the growth of foodborne pathogens. It is an acronym for
food, acidity, time, temperature, oxygen and moisture
.
What are growth factors?
Growth factor,
any of a group of proteins that stimulate the growth of specific tissues
. Growth factors play an important role in promoting cellular differentiation and cell division, and they occur in a wide range of organisms, including insects, amphibians, humans, and plants.
What are the 4 main growth requirements for bacteria?
There are four things that can impact the growth of bacteria. These are:
temperatures, moisture, oxygen, and a particular pH.
How does temperature affect microbial growth?
Generally,an
increase in temperature will increase enzyme activity
. But if temperatures get too high, enzyme activity will diminish and the protein (the enzyme) will denature. … Every bacterial species has specific growth temperature requirements which is largely determined by the temperature requirements of its enzymes.
What are the 10 environmental factors?
Temperature, oxygen, pH, water activity, pressure, radiation, lack of nutrients
…these are the primary ones. We will cover more about metabolism (i.e. what type of food can they eat?)
