Abstract：
OBJECTIVE: Developing energy-saving and ecofriendly strategies for treating harvested Microcystis biomass.
RESULTS: Streptomyces amritsarensis HG-16 was first reported to effectively kill various morphotypes of natural Microcystis colonies at very high cell densities. Concurrently, HG-16 grown on lysed Microcystis maintained its antagonistic activity against plant pathogenic fungus Fusarium graminearum. It could completely inhibit spore germination and destroy mycelial structure of F. graminearum. Transcriptomic analysis revealed that HG-16 attacked F. graminearum in a comprehensive way: interfering with replication, transcription, and translation processes, inhibiting primary metabolisms, hindering energy production and simultaneously destroying stress-resistant systems of F. graminearum.
CONCLUSIONS: The findings of this study provide a sustainable and economical option for resource reclamation from Microcystis biomass: utilizing Microcystis slurry to propagate HG-16, which can subsequently be employed as a biocontrol agent for managing F. graminearum.

摘要：
目的：开发处理收获的微囊藻生物质的节能和生态策略。
结果：首先报道了双股链霉菌HG-16在非常高的细胞密度下有效地杀死各种形态型的天然微囊藻集落。同时,在裂解的微囊藻上生长的HG-16保持了对植物病原真菌镰刀菌的拮抗活性。它可以完全抑制孢子的萌发并破坏禾本科草的菌丝结构。转录组学分析显示，HG-16以全面的方式攻击F.graminearum：干扰复制，转录,和翻译过程，抑制初级代谢，阻碍能源生产，同时破坏禾谷草的抗应激系统。
结论：这项研究的结果为微囊藻生物质的资源回收提供了一种可持续和经济的选择：利用微囊藻浆液繁殖HG-16，随后可将其用作管理F.的生物防治剂。
