The kinetics of calcium ion complexation by ethylene glycol bis(beta-aminoethyl ether)-N,N'-tetraacetic acid (EGTA) were investigated using the stopped-flow technique. This study was performed within the pH range 5.8 to 8.4. The reaction was found to be first order in EGTA and complex order in calci
The effect of the calcium-specific chelant ethylene glycol-bis(fl-aminoethyl ether)-N,N-tetraacetic acid (EGTA) on methanogenic granular sludge from a laboratory-scale upflow anaerobic sludge-blanket (UASB) reactor fed propionate and from a full-scale reactor treating paper-mill waste-water was stud
A simple dilution test for evaluating the individual effect on enzymatic activity of [Ca2+], [EGTA], or [Ca.EGTA] variations in Ca-EGTA buffers is presented. We verified that a 50-fold dilution of the buffer (25-0.5 mM) at constant pH did not affect [Ca2+] (measured with fura-2), whereas [EGTA] and
