Mushroom cultivation is a sustainable agricultural waste utilization method, but the lack of high-value utilization of the produced spent mushroom substrate (SMS) has hindered the development of mushroom cultivation-based circular agricultural systems. Conversion and utilization of SMS via larvae (PBL) have proven to be a high-value AASMS utilization strategy. However, SMS (AASMS), which contains woodchips, is less palatable and digestible for PBL. To solve this problem, in this investigation, we screened out microflora (MF) for AASMS fermentation by comparing the fermentation performance as well as the effect on PBL feed intake, weight gain, and AASMS phytotoxic compound removal efficiency. In addition, by bacterial community analysis, the genera , , and were predicted to be functional bacteria for AASMS fermentation and contribute to palatability and digestibility improvement.
蘑菇栽培是一种可持续的农业废弃物利用方法，但所产生的废菌糠（SMS）缺乏高价值利用阻碍了基于蘑菇栽培的循环农业系统的发展。通过幼虫对SMS进行转化和利用（PBL）已被证明是一种高价值的AASMS利用策略。然而，含有木屑的SMS（AASMS）对PBL来说适口性和消化性较差。为了解决这个问题，在本研究中，我们通过比较发酵性能以及对PBL采食量、体重增加和AASMS植物毒性化合物去除效率的影响，筛选出用于AASMS发酵的微生物区系（MF）。此外，通过细菌群落分析，预测属、属和属为AASMS发酵的功能细菌，并有助于改善适口性和消化性。
