The different strains have been derived through treating E. coli K-12 with agents such as nitrogen mustard, ultra-violet radiation, X-ray etc. An extensive list of Escherichia coli K-12 strain derivatives and their individual construction, genotypes, phenotypes, plasmids and phage information can be viewed at Ecoliwiki.
E. coli K-12, one of two laboratory strains (innocuous) ... H7 is an enterohemorrhagic strain also 2006 North American E. coli outbreak; E. coli O104:H4, ...
Similarly, other strains of E. coli (e.g. the K-12 strain commonly used in recombinant DNA work) are sufficiently different that they would merit reclassification. A strain is a subgroup within the species that has unique characteristics that distinguish it from other strains. These differences are often detectable only at the molecular level ...
[12] Intestinal mucosa-associated E. coli are observed in increased numbers in the inflammatory bowel diseases, Crohn's disease and ulcerative colitis. [13] Invasive strains of E. coli exist in high numbers in the inflamed tissue, and the number of bacteria in the inflamed regions correlates to the severity of the bowel inflammation. [14]
Escherichia coli BL21(DE3) is a commonly used protein production strain. This strain combines several features that allow for excessive expression of heterologous proteins . It is derived from the B lineage of E. coli .
The CyberCell Database (CCDB) is a freely available, web-accessible database that provides quantitative genomic, proteomic as well metabolomic data on Escherichia coli. [1] Escherichia coli (strain K12) is perhaps the best-studied bacterium on the planet and has been the organism of choice for several international efforts in cell simulation ...
Among common E. coli laboratory strains, the 4-HPA degradation pathway is not found in the commonly used K-12 strain, but it does appear in strains B, C, and W (the strain in which most research into the pathway has been done).
The first strains to have the dnaA gene mutated were the temperature-sensitive K-12 strains CRT46 and CRT83, with the corresponding strain numbers beingdnaA46 and dnaA83. In contrary to dnaA mutants, the PC2 strain has a mutation in the dnaC gene, which codes for the loading factor for the DNA helicase dnaB. [8]
