Which of the following factors is known to influence bacterial growth?

Moisture is a critical factor that influences bacterial growth because microorganisms, including bacteria, require water to thrive. The presence of moisture allows bacteria to absorb nutrients and facilitates their metabolic processes. Environments with high moisture levels can promote rapid bacterial multiplication, while dry conditions can inhibit growth. Understanding the importance of moisture helps food managers implement proper food storage and handling practices to minimize bacterial contamination and growth, ensuring food safety. The other factors listed, while they may be relevant in other contexts, do not directly influence the growth of bacteria in the same fundamental way that moisture does.
