The following points highlight the top three methods used for quantitative estimation of microorganisms. The methods are: 1. Total Count of Microbial Population 2. Viable Count of Bacterial Population by Plating Method Principle 3. Viable Count of Bacteria by Drop Technique. Quantitative Estimation of Microorganisms: Method # 1. Total Count of Microbial Population: Total count of microorganisms in any given [...]
The below mentioned article provides a study on the Growth of Bacteria by the help of Turbidimetric Technique. The Growth Theory of Bacteria: The growth of bacteria in a suitable population can be divided into the following phases: (i) The lag phase (ii) The log phase (iii) The stationary phase and (iv) The phase of decline. The duration of each [...]
In this article we will discuss about the Minimum Inhibitory Concentration of Antibiotic for Bacteria. Principle: Antibiotic is a chemical compound produced by some microorganisms, which in low conc. affects the growth of other sensitive microorganisms. The minimum inhibitory conc. (MIC) of an antibiotic is that conc. which just inhibits the growth of a susceptible organism. This conc. primarily depends [...]
