- Abstract
In order to improve flocculation activity of microbial flocculants in extreme environments, the resilience protective effect of compatible solute ectoine on the flocculation activity of flocculant was researched in this paper. Moderate halophilic bacterium Halomonas sp. B01 was isolated, screened and identified from the sediment of a saltern pool. The strain could synthesize flocculant and compatible solute ectoine simultaneously which were partially excreted into the fermentation broth during a fermentation process in this paper. The optimal conditions of flocculation activity by Halomonas sp. B01 flocculant were NaCl 30 g/L, 30 °C and pH 8. Ectoine had significant protective effects of resilience to extracted and purified flocculant in the high salt, high temperatures and alkaline environment. By applying Flocculant/Ectoine co-production fermentation broth by Halomonas sp. B01, the purification treatment of the desulfurized wastewater discharged from the seawater magnesia wet flue gas desulfurization was investigated, the results showed that the removal rate of solid content, turbidity and colority were 91.1%, 90.5% and 71.4%, respectively. The Flocculant/Ectoine co-production fermentation broth by Halomonas sp. B01 had significant effect of purification treatment to the desulfurized wastewater discharged from the seawater magnesia wet flue gas desulfurization.
