Factors Affecting Bacterial Growth

These flashcards cover key concepts regarding the factors that affect bacterial growth as discussed in the lecture.

What are the six factors necessary for bacterial growth?

Oxygen, moisture, nutrients, pH level, light, and salinity.

Why is pH level important for bacteria?

Because some bacteria do not survive in highly acidic or neutral environments, and they have an optimal pH range for growth.

What does salinity refer to in the context of bacterial growth?

Salinity refers to the presence of salt in the environment that some bacteria can tolerate for survival.

Do all living organisms need light to survive?

Not all; while some organisms like plants do, others like bacteria do not necessarily require light for survival and reproduction.

What role does moisture play in bacterial growth?

Moisture is essential for bacteria as it helps in maintaining the necessary environment for metabolism and reproduction.

What happens to bacteria in a highly acidic environment?

Many bacteria cannot survive in highly acidic environments due to their specific pH requirements.
