Sažetak
The aim of this study was to investigate the influence of various carbon sources applied at different initial concentrations of phosphorus and growth conditions, on the phosphate release and uptake in pure culture of Acinetobacter calcoaceticus DSM1532. P-release and uptake studies with various carbon sources applied at different initial concentrations of phosphorus were carried out in alternating anaerobic/aerobic batch experiments. The best P-release and P-uptake rates were obtained when sodium propionate was the carbon source. Glucose addition in the synthetic wastewater caused the lower P-release and uptake ratios, but it does not have significant influence on the final percentage of P-removal. The highest P-release and P-uptake rates were obtained by the highest phosphorus loadings. The highest P-release resulted in the highest P-uptake rates. The observed aerobic P-uptakes in batch test, without preliminary resort to the anaerobic conditions, indicate probable aerobic mechanism of P-uptake by A. calcoaceticus DSM1532. The results of the semi-continuous test indicate the possibility of adaptation of A. calcoaceticus DSM1532 on the high phosphorus loads (up to 100 mg P L-1) in the wastewater.
