The role of protein shell (PS) amendment in altering the fungal community during pig manure (PM) composting was investigated. Six different dosages of PS based on the dry weight of PM (0 %, 2.5 %, 5 %, 7.5 %, 10 %, and 12 %; T1-T6, respectively) were mixed with wheat straw to make the initial feedstock and composted for 42 days. The results showed that Ascomycota, Basidiomycota, and Giomeromycota were the most abundant phyla in all treatments. However, the relative abundance of Giomeromycota was the highest in the control treatment, although a substantially greater population was observed in all treatments. Genus abundance declined steadily from T1 to T6; however, T4 and T6 had smaller populations. Correlation analysis also suggested that T6 amendment increased the overall fungal dynamics and organic matter degradation. Thus, T6 was more efficient to enhance the overall fungal population and dynamics with considerable network connections among all the analyzed parameters.
研究了蛋白质外壳（PS）改良在改变猪粪（PM）堆肥过程中真菌群落中的作用。基于 PM 的干重，将六种不同剂量的 PS（0%、2.5%、5%、7.5%、10%和 12%；分别为 T1-T6）与小麦秸秆混合作为初始原料进行堆肥 42 天。结果表明，在所有处理中，子囊菌门、担子菌门和球囊菌门是最丰富的门。然而，在对照处理中，球囊菌门的相对丰度最高，尽管在所有处理中观察到的种群数量都要大得多。属丰度从 T1 到 T6 稳步下降；然而，T4 和 T6 的种群数量较小。相关性分析还表明，T6 修正案增加了整体真菌动态和有机质降解。因此，T6 更有效地增强了整体真菌种群和动态，所有分析参数之间都有相当多的网络连接。
