Abstract: |
Abstract: Microbial flocculant2p roducing bacteria (HF28 ) were screened from active sludge of wastewater
treatment p lant. To this strain, s culture medium composition and the culture conditionswere op timized. The culture
medium best formula is ( g/500ml) : cane: 10g, ammonium sulfate: 0. 2g, monopotassium phosphate: 2g, dipotassi2
um hydrogen phosphate: 2. 5g, sodium chloride: 0. 05g, hep tahydrate magnesium sulfate: 0. 1g, water: 500ml. The
best culture condition is: the culture temperature: 30. C, the initial pH: 6, rotate speed of shack bed: 120 r/min. |
