Enhancement of the aspartame precursor synthetic activity of an organic solvent-stable protease.
The PST-01 protease is highly stable and catalyzes the synthesis of the aspartame precursor with high reaction yields in the presence of organic solvents. However, the synthesis rate using the PST-01 protease was slower than that observed when thermolysin was used. Structural comparison of both enzymes showed particular amino acid differences near the active center. These few residue difference...

The study of an azo dye removal from liquid medium by modified clay
In this batch study, montmorillonite was modified by a cationic surfactant [hexadecyltrimethylammonium bromide (HDTMA-MMT)] and used as sorbent to remove bromocresol green (BCG) from aqueous solutions. The effect of several factors such as surfactant loading rate onto the clay, contact time, pH, adsorbent dosage, dye concentration, and ion strength were investigated on the sorption. The equilib...
