Abstract
The growth of Chlorella pyrenoidosa microalgae, Nannochloropsis sp. and the bacterium Pseudomonas fluorescens on urea nitrogen industry wastewater has been investigated as an effort to study the potential of these microorganisms in the remediation of nitrogen industry wastewater. Microalgae and bacteria to be grown on media in water treatment plants with high levels of urea fertilizer NH3-N and by 50 percent urea for inhibitory Concentration (IC50). The results showed that the microalgae C. pyrenoidosa able to grow and tolerant on the levels 626.646 ppm of NH3-N and 1426 ppm urea, Nannochloropsis sp. NH3-N and urea 559.854 1398 ppm, whereas P. fluorescens 723.219 ppm and 1623 ppm urea. Microalgae and bacteria growth at that concentration can absorb C. pyrenoidosa NH3-N 53.46% and urea 58%, Nannochloropsis sp. NH3-N 57.5% and 53.71% urea, whereas P. fluorescens NH3-N 62.47% and 62.47% urea. Based on the results of these studies, microalgae and bacteria have potency to be developed as a bioremediation agent in absorbing nitrogen industry wastewater, on the bottom of the pool, deposition microalgae can be used as an alternative energy source.
