In this study, the impact of pig manure on the maturity of compost consisting of spent mushroom substrate and rice husks was accessed. The results showed that the addition of pig manure (SMS-PM) reached 50°C 5days earlier and lasted 15days longer than without pig manure (SMS). Furthermore, the addition of pig manure improved nutrition and germination index. High-throughput 16S rRNA pyrosequencing was used to evaluate the bacterial and fungal composition during the composting process of SMS-PM compared to SMS alone. The SMS treatment showed a relatively higher abundance of carbon-degrading microbes (Bacillaceae and Thermomyces) and plant pathogenic fungi (Sordariomycetes_unclassified) at the end of the compost. In contrast, the SMS-PM showed an increased bacterial diversity with anti-pathogen (Pseudomonas). The results indicated that the addition of pig manure improved the decomposition of refractory carbon from the spent mushroom substrate and promoted the maturity and nutritional content of the compost product.
在这项研究中，评估了猪粪对由废弃蘑菇基质和稻壳组成的堆肥成熟的影响。结果表明，添加猪粪（SMS-PM）比不添加猪粪（SMS）更早达到 50°C，且持续时间长 15 天。此外，添加猪粪提高了营养和发芽指数。高通量 16S rRNA 焦磷酸测序用于评估 SMS-PM 与 SMS 单独堆肥过程中的细菌和真菌组成。在堆肥结束时，SMS 处理显示相对较高丰度的碳降解微生物（芽孢杆菌科和嗜热真菌）和植物病原菌真菌（Sordariomycetes_unclassified）。相比之下，SMS-PM 显示出更高的细菌多样性，具有抗病原体（假单胞菌）的特性。结果表明，添加猪粪可提高废弃蘑菇基质中难降解碳的分解，并促进堆肥产品的成熟和营养含量。
