|a This study examines the primary and ultimate biodegradation of a non-ionic surfactant, an alkylpolyglucoside, in ready biodegradability tests. The surfactant concentration was tested by the anthrone method, while the ultimate biodegradation (mineralization) was analyzed by the total organic carbon determinations. The influence of the concentration on the extent of primary and ultimate biodegradation and the kinetics of degradation also were determined. The primary and ultimate biodegradation was studied at different initial concentrations-15, 25, 50, 75, and 100 mg/L. The increasing concentration of test chemical from 15 to 100 mg/L resulted in a decrease in the relative maximum mineralization rate and longer estimated lag times by a factor of approximately 4.3. During the degradative process, two different stages were noted; these are better described with Quiroga and first-order kinetic models, respectively. For the study of the influence of concentration, the parameters characteristic of the biodegradation profiles in the different biodegradation assays were evaluated
