Influence of the pH of wastewater on the phosphate-accumulating bacterium.
The effects of the pH (3-10) of synthetic wastewater on the pure culture of phosphate (P) – accumulating bacterium Acinetobacter junii were studied. The pH 7 was set as an optimal value for growth, aerobic P-uptake and anaerobic P-release of A. junii. The wastewater having pH 3, 4 and 5 showed negative influence to the growth and metabolism of A. junii. The addition of clay mineral in the reactors having unfavourable pH (4 and 5) resulted in the shift of pH toward the neutral pH 7 due to its buffering ability. The addition of clay enabled the survival of A. junii at low pH 4 and 5. The majority of the cultured bacterial population was immobilized onto the clay particles, showing that clay can be good carrier of bacteria. It can be concluded that the addition of clay could impair the influence of unfavourable pH of the wastewater on the A. junii due to its buffering capacity and immobilization of bacteria.
