List of 4 Major Microbial Interactions | Microbiology

Here is a list of four major microbial interactions:- 1. Clay-Humus-Microbe Interaction 2. Plant-Microbe Interactions 3. Animal-Microbe Interactions 4. Microbe-Microbe Interactions. 1. Clay-Humus-Microbe Interaction: Clay mineral (and humic substances) affects the activity, ecology and population of microor­ganisms in soil. Clays modify the physicochemical environment of the microbes which either enhance or attenuate the growth of individual microbial population. After release [...]

Purification of Water: 3 Methods | Microbiology

The following points highlight the top three methods adopted for purification of water. The methods are: 1. Sedimentation 2. Filtration 3. Disinfection. Method # 1. Sedimentation: Sedimentation is done when water consists of large sized organic materials such as leaves, and gravels which have run off from the soil. Suspended particles settle down depending on their size and weight and [...]

Properties of Soil | Microbiology

Physicochemical properties of soil include soil texture, water, air, inorganic chemicals, and organic matter. The biological factors of soil are soil flora and fauna. Mechanical composition (texture) of soil is determined on the basis of size of soil particles i.e. sand, silt and clay particles (Table 30.1). However, the ratio of soil particles governs the porosity (pore size of soil), [...]
