Final answer:
The acronym for the factors of bacterial growth is FATTOM, which includes Food, Acidity, Time, Temperature, Oxygen, and Moisture. These factors, especially during the Log Phase, are crucial for bacteria to multiply exponentially under optimal conditions. Various methods are used in labs to control and study these growth characteristics.
Step-by-step explanation:
The acronym that represents the factors for bacterial growth is FATTOM, which stands for Food, Acidity, Time, Temperature, Oxygen, and Moisture. These factors are essential for bacteria to thrive and reproduce. For example, food supplies the nutrients needed for bacterial growth.
During the Log Phase, bacteria undergo exponential growth, dividing rapidly. This phase can be monitored using various methods, including the direct viable cell count and measuring the turbidity of the culture. Different growth requirements, including oxygen preferences, temperature, and pH levels, are essential in differentiating among bacterial species and their growth characteristics.
In an experimental setting, such as using a chemostat to study bacterial growth, maintaining the log phase requires careful balance of nutrient supply and waste removal, as well as optimum environmental conditions like oxygen level for aerobic bacteria. Furthermore, the growth curve of a bacterial population typically follows four stages: lag, logarithmic (exponential), stationary, and death phases. Each phase requires specific conditions to maximize the growth and study of bacterial cultures.
