Of these ranks, domains are the most general level of categorization. Presently, scientists classify all life into just three domains, Eukaryotes, Bacteria and Archaea. [2] Bacterial taxonomy is the classification of strains within the domain Bacteria into hierarchies of similarity.
In the 1980s microbial phylogenetics went into its golden age, as the techniques for sequencing RNA and DNA improved greatly. [7] [8] For example, comparison of the nucleotide sequences of whole genes was facilitated by the development of the means to clone DNA, making possible to create many copies of sequences from minute samples.

Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
Bacterial phyla constitute the major lineages of the domain Bacteria.While the exact definition of a bacterial phylum is debated, a popular definition is that a bacterial phylum is a monophyletic lineage of bacteria whose 16S rRNA genes share a pairwise sequence identity of ~75% or less with those of the members of other bacterial phyla.
Food microbiology laboratory at the Faculty of Food Technology, Latvia University of Life Sciences and Technologies. The branches of microbiology can be classified into pure and applied sciences. [1] Microbiology can be also classified based on taxonomy, in the cases of bacteriology, mycology, protozoology, and phycology.
Bacteriology is the study of bacteria and their relation to medicine. Bacteriology evolved from physicians needing to apply the germ theory to address the concerns relating to disease spreading in hospitals the 19th century. [5] Identification and characterizing of bacteria being associated to diseases led to advances in pathogenic bacteriology.
Cytophagales is an order of non-spore forming, rod-shaped, Gram-negative bacteria that move through a gliding or flexing motion. [4] These chemoorganotrophs are important remineralizers of organic materials into micronutrients. [5]
