The fungal dynamics and its correlation with physicochemical and gaseous emission were investigated using metagenomics and Heat map illustrator (HEMI). Five different concentrations of wheat straw biochar (WSB) were applied to poultry manure (PM) and composted for 50 days; those without the WSB treatment were used as a control. The results revealed the dominant phyla to be Chytridiomycota, Mucoromycota, Ascomycota and Basidiomycota, while Batrachochytrium, Rhizophagus, Mucor, and Puccinia were the superior genera. In particular, the diversity of Chytridiomycota and Ascomycota was more abundant among all of the treatments. Overall, the diversity of the fungal species was correspondent, but relative abundance varied significantly among all of the composts. Principle Coordinate Analysis (PCoA) and Non-Metric Multi- Dimensional Scaling (NMDS) indicated that different concentrations of WSB applied treatments have significantly distinct fungal communities. In addition, correlation analyses of fungal interactions with environmental elements via HEMI also indicate a clear difference among the treatments. Ultimately, the relative abundance of fungal composition significantly influenced the PM compost treated by the WSB.
采用宏基因组学和 Heat map illustrator(HEMI)研究了真菌动态及其与理化性质和气体排放的相关性。将 5 种不同浓度的小麦秸秆生物炭(WSB)应用于禽粪(PM)并进行了 50 天堆肥;未添加 WSB 处理的作为对照。结果表明,优势菌门为接合菌门、毛霉门、子囊菌门和担子菌门,而优势属为蛙壶菌属、根毛菌属、毛霉属和柄锈菌属。特别是所有处理中,接合菌门和子囊菌门的多样性更为丰富。总体而言,真菌物种的多样性是一致的,但所有堆肥中的相对丰度差异显著。主坐标分析(PCoA)和非度量多维尺度分析(NMDS)表明,应用不同浓度 WSB 的处理具有明显不同的真菌群落。此外,通过 HEMI 对真菌与环境要素相互作用的相关分析也表明,处理之间存在明显差异。最终,真菌组成的相对丰度显著影响了 WSB 处理的 PM 堆肥。
