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.
Enterohemorrhagic E. coli (EHEC) Enteroaggregative E. coli (EAEC) Uropathogenic E. coli (UPEC) Verotoxin-producing E. coli; E. coli O157:H7 is an enterohemorrhagic strain also 2006 North American E. coli outbreak; E. coli O104:H4, also 2011 E. coli O104:H4 outbreak; Escherichia coli O121; Escherichia coli O104:H21; Escherichia coli K1, meningitis
From 2002 to 2010, a team at the Hungarian Academy of Science created a strain of Escherichia coli called MDS42, which is now sold by Scarab Genomics of Madison, WI under the name of "Clean Genome E. coli", [123] where 15% of the genome of the parental strain (E. coli K-12 MG1655) were removed to aid in molecular biology efficiency, removing IS ...
Hash oil is an extracted cannabis product that may use any part of the plant, with minimal or no residual solvent. It is generally thought to be indistinct from traditional hashish , at-least according to the 1961 UN Single Convention on Narcotic Drugs that defines these products as "the separated resin, whether crude or purified, obtained from ...
RegulonDB is a database of the regulatory network of gene expression in Escherichia coli K-12. [1] [2] RegulonDB also models the organization of the genes in transcription units, operons and regulons. A total of 120 sRNAs with 231 total interactions which all together regulate 192 genes are also included.
KdpD/KdpE is a TCS system that is found in Escherichia coli and produces K+ transporter Kdp-ATPase. This TCS system was characterized first in the bacterial species of E. coli. [17] The transporter is used as a scavenging system for K+ when it is extremely limited. The TCS system for E. coli has four distinct proteins from one single operon ...
Using passive agglutination, Kunin detected the O-antigen found in the lipopolysaccharide (LPS) of E. coli. During the experiments, Kunin noticed that there was cross-reactivity between the rabbit antisera and many of the E. coli strains. One of the sera, O14, reacted to an antigen found in a large range of E. coli strains. Notably, the antigen ...
E.coli", [b 18] where 15% of the genome of the parental strain (E. coli K-12 MG1655) were removed to aid in molecular biology efficiency, removing IS elements, pseudogenes and phages, resulting in better maintenance of plasmid-encoded toxic genes, which are often inactivated by transposons.
