With the purpose of investigating the phosphate removal ability of Bacillus subtilus isolated f-rom fish processing wastewater, five bacterial strains were se-lected for experiments to determine the density of microorganisms, the suitable phosphate concentration range, and phosphate treatment efficiency comparing with products on the market under aerobic conditions. The results showed that the phosphate treatment ability of the bacteria strains was more than 50% effective with a density of 103 microorganisms/mL
phosphate concentration in the range of 10-100 ppm and in aerobic conditions. The processing ability of the mixture of bacteria strains has similar results compared with products on the market (Bio-Em, EcocleanTM, Jumpo ARKeywords Bacillus subtilus, phosphate, seafood processing wastewater.
