Question

Quizplus · Accepted Answer

All listed factors are crucial for promoting microbial growth. Optimal food resources ensure that microbes have the necessary nutrients. pH levels must be controlled because each microbe has a preferred pH range. Ideal temperature is essential because it affects the metabolic rate of microbes. Oxygen requirements vary among microbes, with some requiring oxygen (aerobic), others thriving in its absence (anaerobic), and some being flexible (facultative anaerobes).
