摘要：

The effect of the calcium-specific chelant ethylene glycol-bis(beta-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 studied. Upon treatment with EGTA both sludge types showed a decrease in the calcium and phosphorus content and a release of protein and polysaccharides, leading to a decrease in strength of papermill granular sludge and a disintegration of propionate-grown granules. After treatment of propionate-grown granular sludge with high EGTA concentrations, the methanogenic activity with propionate and acetate as test substrates decreased by 88 and 33%, respectively. The marked reduction in propionate oxidation activity may be caused by a disruption of the special juxtapositioning of bacteria in the granules.
