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 [...]
After reading this article you will learn about the potassium and ammonium fixation in soils. Cation fixation in soils occurs when exchangeable or water soluble cations are converted to a form that cannot be readily extracted with a neutral solution of a salt. Potassium (K+) and ammonium (NH4+) ions have been primarily involved in such reactions. Fixation of NH4+ takes [...]
After reading this article you will learn about the anoxygenic and oxygenic photosynthesis. The Anoxygenic Photosynthesis: Anoxygenic photosynthesis uses energy from sunlight to couple the reduction of C in CO2 to the anaerobic oxidation of S in S0 or H2S. If one is accustomed to thinking of S oxidation in a strictly aerobic sense, then anaerobic S oxidation appears contradictory. [...]
