OBJECTIVE: One strain of photosynthetic bacteria associated with highly removal capability of pollutant was isolated, and investigated about its growth.
METHODS: By using an enrichment culture and plate dilution method, one strain of bacteria, named VOTO1-G, was isolated from river sediment mainly received domestic wastewater. The VOTO1-C bacteria was researched about its growth law, and identified by molecular biology method, and further used to test its ability in the removing of nitrogen, phosphorus and organic compound from eutrophic water by 0.05 per thousand, 0.1 per thousand and 0.2 per thousand.
RESULTS: By checking the individual morphology, colony culture characteristics, DNA sequencing and 16S rDNA gene bank, VOTO1-G was identified as Rhodopseudomonas palustris. The isolated bacteria strain had some nitrogen, phosphorus and organic compound removal ability.
CONCLUSION: One strain of photosynthetic bacteria was successfully isolated from sewage sediments. Its removal capacity of nitrogen, phosphorus and organic compound from eutrophic water was good, which removed COD 12%, TP 25%, TN 13%.
