Escherichia coli strains

On solid medium, Azospirilhim and Escherichia coli strains were plated on LB agar with l%(w/v) pectin and after six days of incubation, the plates were overlayed with 2% (w/v) solution of hexadecyltrimetyl ammonium bromide (HTAB) (Plazinski and... 

The degradation of phenylmercuric acetate to benzene, methylmercuric chloride to methane, and ethylmercuric chloride to ethane and Hg + is apparently carried out by different enzymes from the plasmid-carrying Escherichia coli strain K12 (R831) (Schottel 1978) and Pseudomonas sp. Resistance to organic mercury compounds has also been found in clinical isolates of nontuber-culous, rapidly growing mycobacteria (Steingrube et al. 1991) and can present a challenge in the clinical environment. 

High-specific activity D-P- H] panthothenic acid (Figure 10.8) was prepared from commercially available p-[3-3H]alanine using Escherichia coli strain DVl, which converted 85 to 90% of the input p-[3-3H]alanine to extracellular D-[3- H]panthoth-enate under appropriate growth conditions. The radiolabeled vitamin was purified...

An (5)-specific alcohol dehydrogenase gene from Rhodococcus erythropolis and GDH from Bacillus subtilis were ligated into one plasmid, which was expressed in Escherichia coli strain DSM14 459 to provide an (S)-selective whole-cell catalyst. 

A recombinant Escherichia coli strain containing the cloned limonene hydratase gene was able to grow in a water-limonene two-phase system and converted limonene to a-terpineol [36], Limonene, a cost-effective and readily available monoterpene, served both as the substrate and the neat solvent for the production of a-terpineol. 

Imino-3,4-dihydro-pyrimido[l,2-f][l,3]benzothiazine (PD4404182) was identified as a selective inhibitor of Gram negative Escherichia coli strains <2000JA9334>.

The Koenigs—Knorr reaction109,130 of the halide 112 with methyl 2,3-di-O-acetyl-jS-D-ribofuranoside (123) in 3 1 (v/v) benzene—1,4-dioxane in the presence of silver carbonate gave a low yield of the disaccharide 124 (see Scheme 34). Compound 124 and its deacetylation and deesterification products, 125 and 126, were used as model compounds for 1H- and 13C-n.m.r. studies47,107 of the KDO-containing exopolysaccharides from Escherichia coli strains LP 1092 and 06 K13 H1 (refs. 84 and 86). 

These circumstances became apparent to the authors when they attempted to study the formation of KDO 8-phosphate as catalyzed by purified bacterial extracts. These extracts did not catalyze the formation of KDO 8-phosphate from D-ribose 5-phosphate, but required D-arabinose 5-phosphate as the substrate Heath and Ghalambor29 showed that the KDO 8-phosphate synthetase reaction, observed in Pseudomonas extracts by Levin and Racker, is also catalyzed by extracts from Escherichia coli strains 0 111 B4 and J-5. Rick and Osborn136 showed that the KDO 8-phosphate synthetase from a Salmonella typhimurium mutant conditionally defective in cell-wall synthesis had a KM of 6 mM as compared to a KM of 170 pM for the enzyme from wild-type cells.
