Due to the ongoing Pandemic, we strive to educate ourselves better. We try to understand the science affecting our health. And how we can work better to prevent bad bacteria and viruses away. Most bacteria are harmful, but there are those beneficial to our body. As we understand how bacteria works, we also understand its effects on our body. The study of bacterial growth allows us further to foresee and prevent possible illnesses.

What Are The 4 Phases Of Bacterial Growth? 

Bacteria is one of the fastest reproducing organisms in the world. Some doubled as fast as 4 minutes. The 4 phases of bacterial growth are as follows:

  1. The Lag Phase: This phase represents the stage for active growth. At this point, the bacteria grows larger in size to prepare for reproduction. Although there is an increase in volume, there is no increase in number yet.
  2. Log or Exponential Growth Phase: Bacteria undergo systematic growth and double in number. This is also the stage where antibacterial substances are most effective.
  3. Stationary Phase: Due to many factors, the growth of bacteria cells slows down. Then reaches a plateau where the number of new bacteria equals the number of bacteria dying.
  4. Death Phase: After exhausting all the nutrients, more and more cells die. If there are more cells dying than cells created this stage becomes the death phase.

What Are The 6 Conditions For Bacterial Growth?

It is frightening to know that bacteria can grow that fast. Especially knowing that bacteria is not visible to the naked eye. That is why it is helpful to identify the conditions that encourage bacterial growth. This allows us to know which conditions to cut and prevent. There are 6 identified conditions that allow bacterial growth faster.

  1. Food: Like any other living organisms Bacteria also needs food to survive. It is especially happy with carbohydrates and proteins such as meats, dairy, and eggs.
  2. Acidity: Based on pH level, bacteria will most likely strive in neutral to acidic ranges of 7.5 to 4.6 level. A condition most food lies in.
  3. Temperature: Bacteria grows in a temperature between 4°C to 60°C. This is the danger zone in Food industry. Going out of the danger zone does not stop the growth of bacteria instead it only slows it down. This is why it is important to store perishable food at the right temperature right away.
  4. Time: With the right amount of time and rate of growth ,bacteria grows at an exponential number. For this reason, you should store perishable food at the right temperature or cook it as soon as possible.
  5. Oxygen: Bacteria need oxygen to survive and multiply. With proper processing, food will have no exposure to oxygen. Although, there are some bacteria that can still survive without oxygen.
  6. Moisture: Bacteria need moisture. And it will continue to grow with the presence of moisture. That is why dry goods have less time to get spoiled as compared to wet or moist food.
