After reading this article you will learn about the continuous culture of micro-organisms. The typical bacterial growth curve includes three transitional periods between growth phases. This means that not all the cells are in identical physiological conditions. Time is required for some cells to catch up with others. In terms of physiological conditions, the growth curve includes young, actively metabolizing [...]
After reading this article you will learn about the synchronous cultures of bacteria. Synchronous cultures are composed of populations of cells that are at the same stage of their life cycle. All the cells in the culture will divide at the same time will grow for a generation time, and all will divide again at the same time. Thus the [...]
This article throws light upon the three ways for the measurement of bacterial growth. The ways are: 1. Determination of the Number of Cells. 2. Determination of Cell Mass 3. Determination of Cell Activity. Way # 1. Determination of the Number of Cells Directly: Breed Method: A known volume of cell suspension (0.01 ml) is spread uniformly over a glass [...]
