The 6.5% salt broth test is used to analyze the tolerance level of various bacteria under halophilic conditions. This test is used because most organisms cannot survive in high salt concentrations while Staphylococci , Enterococci , and Aerococci are all expected to tolerate 6.5% NaCl concentrations.
The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using PhyloRank and the ...
Bacterial taxonomy is subfield of taxonomy devoted to the classification of bacteria specimens into taxonomic ranks. Archaeal taxonomy are governed by the same rules. In the scientific classification established by Carl Linnaeus , [ 1 ] each species is assigned to a genus resulting in a two-part name.
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.
Genotypic repair, also known as genetic repair, is the removal or correction of impermissible entries in the chromosome that violate restrictions. In phenotypic repair, the corrections are only made in the genotype-phenotype mapping and the chromosome remains unchanged. [ 1 ]
A method was introduced to hybridize a large number of DNA samples against numerous DNA probes on a single membrane. The samples would need to be separated into individual lanes within the membrane, which would then be rotated to allow simultaneous hybridization with multiple DNA probes. [6]
The analytical profile index, or API, is a classification system for bacteria based on biochemical tests. The system was developed to accelerate the speed of identifying clinically relevant bacteria. It can only be used to identify known species from an index. [1] The data obtained are phenotypic traits.
Bergey's Manual Trust was established in 1936 to sustain the publication of Bergey's Manual of Determinative Bacteriology and supplementary reference works. The Trust also recognizes individuals who have made outstanding contributions to bacterial taxonomy by presentation of the Bergey Award and Bergey Medal, jointly supported by funds from the Trust and from Springer, the publishers of the ...
