What are the four factors that help bacteria grow and multiply?

Question

Accepted Answer

Bacteria thrive under specific conditions, including temperature, moisture, nutrients, and pH levels.

Temperature: Most bacteria grow best between 20°C and 40°C. For example, pathogenic bacteria like Salmonella thrive at body temperature.
Moisture: Bacteria require water to grow. Foods with high moisture content, like fruits and vegetables, are more prone to bacterial growth.
Nutrients: Bacteria need nutrients such as carbohydrates, proteins, and fats. For instance, meat and dairy products are rich in nutrients that support bacterial growth.
pH Levels: Most bacteria prefer a neutral pH (around 7). Foods like pickles (acidic) inhibit bacterial growth.
