Overview
To properly control micro-organisms, we need to understand what makes them
grow and multiply.
Micro-organisms only need small amounts of nutrients and moisture to grow,
which is why manufacturing facilities need to be kept clean and dry.
The growth of micro-organisms depends on the combination of the below factors:
Nutrients
Moisture
Physical environment
GROWTH OF MICRO-ORGANISMS
Nutrients
The main nutrients are:
Carbon, from carbon dioxide (CO2) or organic
compounds
Nitrogen, from organic compounds such as amino
acids, and inorganic compounds such as ammonia
Hydrogen, oxygen, sulphur, and phosphorus, which
are all found in water and the atmosphere.
Moisture
Just like humans, micro-organisms need water to grow.
Water is responsible for a large majority of a cell's
makeup, and has roles in nutrition and cellular
metabolism.
