The reason behind the appearance of different growth curves than usual in the provided graph. Introduction: The bacterial cells being grown on a culture media exhibit a growth pattern. An exponential growth is observed when the cells are grown in batch culture. The concentration of the bacterial cells can be obtained by using a special device called spectrophotometer which works on the concept of optical density. Higher optical density means larger number of bacterial cells are present in the provided sample.

Question

Definition Definition Phase during which the number of bacteria cell deaths gradually equals the number of viable or actively dividing cells due to decreased reproduction rate. Microbes utilize all nutrients present in the growth medium to multiply during the growth of the bacterial population, which results in the deposition of waste matter, toxins, and inhibitory compounds in the media. This changes media conditions, such as temperature and pH, creating an unfavorable environment for bacterial growth. Here, the growth rate becomes stabilized.
