an alkylhydroperoxidase AhpD-like protein (subfamily 84), identified here as having a low clustering coefficient, was found to be the enzyme RcsA involved in hypochlorous acid degradation inPseudomonas aeruginosa[50]. Therefore, this method identified true genetic associations with Cld. ...
H+ ions present in HCl solution are too weak (they have too low electronegativity) oxidizers to dissolve copper. H2O2 is strong oxidizer, especially in acididc solutions. That's why copper dissolves after H2O2 is added. « Last Edit: June 01, 2005, 03:24:10 PM by Borek » Logged ...
Carbon monoxide (CO) is a ubiquitous atmospheric trace gas produced by natural and anthropogenic sources. Some aerobic bacteria can oxidize atmospheric CO and, collectively, they account for the net loss of ~250 teragrams of CO from the atmosphere each y
To quantify the intracellular H2S, log-phase cells were collected and re-suspended in a reaction buffer (50 mM Tris-HCl, pH 9.5, 1% Triton X-100, 50 μM DTPA). To disrupt cells, they were incubated at 95 °C for 15 min. The HS− in cell lysate was labeled with monobromobimane ...
The sample was diluted to 0.6 M final Gn-HCl concentration with 25 mM ammonium bicarbonate buffer. For digestion of protein, trypsin was added in a trypsin-to-lysate ratio of 1:50 after and incubation was performed overnight at 37 °C. The supernatant was vacuum dried and the peptides ...
However, since this coloring agents must be added in a form of an oxide obtained by dissolving in HCl, the color may be damaged when the coloring agents are baked at 1,350 to 1,600 degrees C. Further, when the above-described various coloring agents are combined to be used, there are...

I agree with you, but it does not explain why in particular the combination H2O2/HCl is such a powerful oxidizer. A mixture H2O2/H2SO4 at the same normality is not nearly as potent as H2O2/HCl. The reason for this is the very strong complexing properties of the chloride ion, even in...
The reaction was stopped by the addition of 420 µL 12 M HCl. To remove HCl and bring the target compound into an organic solvent that can be easily evaporated, we performed liquid-liquid extractions using a mixture of ethyl acetate/toluene (85/15 (v/v)). Each sample was ...
