The following points highlight the top four tests for the presence of coliforms in water. The tests are: 1. Sanitary Tests for Coliforms 2. The Most Probable Number of Coliforms 3. The Defined Substrate Test 4.IMViC Tests. Test # 1. Sanitary Tests for Coliforms: The original test for the presence of coliform in water is done by standard multiple tube [...]
The nematophagous fungi are of three main types on the basis of ecological habit: 1. Nematode-Trapping Fungi 2. Endoparasitic Fungi and 3. Egg Parasites. Type # 1. Nematode-Trapping Fungi: Fungi capturing nematodes are called nematode-trapping fungi. Such fungi have evolved structural adaptations to trap or penetrate their prey. They may be predatory or endoparasites. There are varieties of ways by [...]
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 microorÂganisms in soil. Clays modify the physicochemical environment of the microbes which either enhance or attenuate the growth of individual microbial population. After release [...]
