Abstract :
A strain named n-3 was isolated for its flocculating efficiency could achieve 84.86% from the domestic wastewater of Urtmqi City. The strain was identified as Pseudomonas fragi based on its morphological and 16SrDNA sequence analysis. This study showed that the optimum pH and the optimum temperature for producing bio-flocculants were 7.0 and 30°C respectively.
