Analyzing the Catalytic Role of Active Site Residues in the Fe-type Nitrile Hydratase from \u3cem\u3eComamonas testosteroni\u3c/em\u3e Ni1 [PDF]

, 2015
A strictly conserved active site arginine residue (αR157) and two histidine residues (αH80 and αH81) located near the active site of the Fe-type nitrile hydratase from Comamonas testosteroni Ni1 (CtNHase), were mutated. These mutant enzymes were examined

Mineral Concentrations in Different Types of Honey Originating from Three Regions of Continental Croatia

Foods
Honey has been recognized as a reliable indicator of environmental quality because of honeybees’ intense foraging activity, which brings them into contact with many persistent organic pollutants around the hive. In this study, four types of honey (meadow,

Phase Chemistry of Tank Sludge Residual Components [PDF]

, 2002
Experiments began with ''neutralization'' of iron (III)-aluminum nitrate solutions by addition of sodium hydroxide at room temperature. The final pH of most experiments was approximately 13.7. The samples were neutralized in PP or HDPE bottles that were then submerged in a water bath and aged at 90 C for up to 120 h.
