以自主驯化的光合细菌混合菌群M PB1为研究对象,研究固定化M PB1菌群最优固定化条件,及其对水产养殖尾水的处理效果.高通量测序结果显示,不同驯化培养阶段的M PB1群落结构存在显著差异.培养完全阶段M PB1优势菌属为红假单胞菌属(Rhodopseud-omonas)71.7％ ～85.2％、脱硫弧菌属(Desulfobibrio)2.5％ ～7.7％、蛋白质菌属(Proteini-clasticum)0.7％ ～8.43％ 和拟杆菌属(M acellibacteroides)1.9％ ～4.2％.群落相互作用分析表明菌群间协同作用提升了M PB1的生物净化能力.以壳聚糖(CS)和海藻酸钠(SA)复合物作为固定材料、交联时间为6 h、SA和CS的体积分数分别为1％ 和4％ 的包埋条件下固定M PB1菌...

Taking the self domesticated photosynthetic bacteria mixed flora MPB1 as the research object,the optimal immobilization conditions of the immobilized MPB1 flora and its treatment effect on aquaculture tail water were studied.High throughput sequencing results showed that there were significant differences in MPB1 community structure at different domestication and culture stages.In the complete culture stage,the dominant bacteria of MPB1 are Rhodopseudomonas(71.7%~85.2%),Desulfobibrio(2.5%~7.7%),Proteiniclasticum(0.7%~8.43%)and Macellibacteroide...
