In this article we will discuss about the features and classification of four general groups of microorganisms:- 1. Rickettsias 2. Chlamydias 3. Planctomycetes 4. Verrumicrobiota. Group # 1. Rickettsias: Most live in an obligate intracellular association parasitic or mutualistic, with eukaryotic hosts (vertebrates or arthropods); a few can be grown on moderately complex bacteriological media containing blood. Their cell walls [...]
In this article we will discuss about:- 1. Definition of Meta-Genomics 2. Study of Meta-Genomics 3. Applications. Definition of Meta-Genomics: The meta-genomics refers to the collection of genes sequenced from the environmental samples. Due to advancement in molecular biology, meta-genomics is described as sequencing of genetic material from environment i.e. uncultured samples. Kevin Chen and Lior Pachter (U.S.A) defined meta-genomics [...]
The following points highlight the three main system of classifications of microorganism. The system of classifications are: 1. Five-Kingdom System of Classifications 2. Eight Kingdom System of Classification 3. Three Domain System of Classification. 1. Five-Kingdom System of Classifications: Later, prokaryotic and eukaryotic organisms were distinguished on the basis of cell anatomy, and the concept of a bacterium as a [...]
