title: A new enzymatic technique to estimate the efficiency of microbial degradation of pollutants.
abstract: Dynamics of active sludge microorganism activity in aerotanks under chemostat conditions has been studied. Dependence of microorganism catalase activity has been found to depend on residual substrate concentration in proportion to the biomass of microorganisms. Experimental data and field observations has formed the basis to develop a technique to evaluate in relative units the amount of the substrate consumed by biocenosis of the active sludge in the air tanks of purification facilities.
