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 [...]

7 Microorganisms Found in Soil | Microbiology

Microorganisms which live in soil are algae, bacteria, actinomycetes, bacteriophages, protozoa, nema­todes and fungi (Fig. 30.2). A brief description of soil microorganisms has been given below: 1. Soil Algae: Soil algae (both prokaryotes and eukaryotes) luxuri­antly grow where adequate amount of moisture and light are present. They play a variety of roles in soil. One of the important role of [...]
