Catalytic sterilization of Escherichia coli K 12 on Ag/Al2O3 surface.
Bactericidal action of Al(2)O(3), Ag/Al(2)O(3) and AgCl/Al(2)O(3) on pure culture of Escherichia coli K 12 was studied. Ag/Al(2)O(3) and AgCl/Al(2)O(3) demonstrated a stronger bactericidal activity than Al(2)O(3). The colony-forming ability of E. coli was completely lost in 0.5 min on both of Ag/Al(2)O(3) and AgCl/Al(2)O(3) at room temperature in air. The configuration of the bacteria on the ca...
متن کاملHfr Strains of Escherichia coli K-12
Since the first reports by Cavalli-Sforza (9) and Hayes (24) of strains of Escherichia coli K-12 which are conjugational donors of chromosomal markers at high frequency (Hfr strains), many other Hfr strains have been isolated and our understanding of the mechanisms involved in Hfr formation has increased considerably. All Hfr strains arise from the integration of a conjugative plasmid into the ...
متن کاملPhosphoglucomutase mutants of Escherichia coli K-12.
Bacteria with strongly depressed phosphoglucomutase (EC 2.7.5.1) activity are found among the mutants of Escherichia coli which, when grown on maltose, accumulate sufficient amylose to be detectable by iodine staining. These pgm mutants grow poorly on galactose but also accumulate amylose on this carbon source. Growth on lactose does not produce high amylose but, instead, results in the inducti...
متن کاملGuanylate kinase of Escherichia coli K-12.
We have identified the gene gmk, in the same operon as rpoZ, spoT, and recG at about 82 minutes on the Escherichia coli chromosome. The gmk (GMP kinase) gene encodes a peptide of 23,592 Da, possessing extensive similarity to the amino acid sequence of guanylate kinase from yeast. To confirm that gmk truly encodes guanylate kinase and to explore some of its enzymatic features, we have overproduc...
متن کاملTransduction in Escherichia Coli K-12.
SYSTEM of genetic transduction has been discovered in the sexually fertile A K-12 strain of Escherichia coli. This transduction is mediated by lambda, a temperate phage for which K-12 is normally lysogenic. The distinctive features of the lambda-K-12 system include the following: (1) The transductions are limited to a cluster of genes for galactose fermentation. The GaZ loci are closely linked ...
