Bacterial taxonomy is the classification of strains within the domain Bacteria into hierarchies of similarity. This classification is similar to that of plants , mammals , and other taxonomies. However, biologists specializing in different areas have developed differing taxonomic conventions over time.
Microbial taxonomy: the naming and classification of microorganisms Bacterial taxonomy: the naming and classification of bacteria; Microbial systematics: the study of the diversity and genetic relationship of microorganisms; Microbial phylogenetics: the study of the manner in which various groups of microorganisms are genetically related [4]
This article lists the orders of the Bacteria.The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI) [2] and the phylogeny is based on 16S rRNA-based LTP release 132 by The All-Species Living Tree Project.
Bacteria display a large diversity of cell morphologies and arrangements. Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea).
Thermus aquaticus is a species of bacteria that can tolerate high temperatures, one of several thermophilic bacteria that belong to the Deinococcota phylum. It is the source of the heat-resistant enzyme Taq DNA polymerase, one of the most important enzymes in molecular biology because of its use in the polymerase chain reaction (PCR) DNA amplification technique.
The Timpe and Runyon classification of nontuberculous mycobacteria is based on the rate of growth, production of yellow pigment and whether this pigment was produced in the dark or only after exposure to light. [1] It was introduced by Ernest Runyon in 1959. [2] On these bases, the nontuberculous mycobacteria are divided into four groups:
Following present classification, there are a little less than 9,300 known species of prokaryotes, which includes bacteria and archaea; [189] but attempts to estimate the true number of bacterial diversity have ranged from 10 7 to 10 9 total species—and even these diverse estimates may be off by many orders of magnitude.
[1] [2] It denotes the rules for naming taxa of bacteria, according to their relative rank. As such it is one of the nomenclature codes of biology. Originally the International Code of Botanical Nomenclature dealt with bacteria, and this kept references to bacteria until these were eliminated at the 1975 International Botanical Congress. An ...
