This study performs an integrated evaluation of the formation and distribution of algal-bacterial bioflocs in aquaculture wastewater supplemented with agricultural waste, together with an assessment of their behavior in the microbial community and of the water quality of the system in which a new bioaugmentation strategy was applied. Results indicated that the dual bioaugmentation strategy via the consortium addition of bacteria and microalgae had the highest formation performance, providing the most compact biofloc structure (0.59 g/L), excellent settleability (71.91%), and a large particle diameter (4.25 mm). The fed-batch supplementation of molasses and rice bran, in terms of changes in the values of COD, NH, NO, and PO, stimulated the formation of biofloc through algal-bacterial bioflocs and microbe-rice bran complexes within a well-established microbial community. These findings provide new insight into the influence of bioaugmentation on the formation of an innovative algal-bacterial biofloc.

双生物强化策略，以农业废弃物作为替代营养源和生物质支持材料，增强水产养殖废水中藻菌共生生物絮团的形成
本研究对补充有农业废物的水产养殖废水中藻细菌生物絮团的形成和分布进行了综合评估，同时评估了它们在微生物群落中的行为以及采用新的生物强化策略的系统的水质。应用。结果表明，细菌和微藻联合添加的双重生物强化策略具有最高的形成性能，提供最致密的生物絮体结构（0.59 g/L）、优异的沉降性（71.91%）和大粒径（4.25 mm） 。分批补料糖蜜和米糠，通过 COD、NH、NO 和 PO 值的变化，通过藻类-细菌生物絮凝物和微生物-米糠复合物在成熟的微生物体内刺激生物絮凝物的形成社区。这些发现为生物强化对创新藻类-细菌生物絮团形成的影响提供了新的见解。
