The bagasse of (maguey pulquero) is a residue generated during the exploitation of the plant to obtain pulque, inulin, honey, etc. Due to its chemical composition, it can be used for the cultivation of fungi of the genus and the subsequent use of the degraded material "degraded substrate (DS)" as a support for the germination of vegetables. The objective of the study was to characterize the bagasse of maguey pulquero biodegraded by as a new perspective in its value chain, and subsequent use for the germination of (tomato). The DS was recovered at 60 d from the culture, characterized physicochemically and the conformation of the plant tissue was observed by scanning electron microscopy. The DS showed a decrease in protein (4.8-3.3 %) content and fibrous fraction (54-36 %), but dry matter digestibility increased from 47 to 71 %; in addition, changes in mineral composition were observed, mainly in calcium concentration (6 %). Due to its composition, it is possible to revalue DS in the germination of L. to reduce the use of peat moss (commercial peat). The results show that up to 25 % of maguey DS mixed with 75 % peat moss can be used (25:75), reaching a germination percentage of 85 % and increasing the seedling emergence speed index from 0.96 - 1.25. Concluding that it is possible to implement a circular strategy in which agave bagasse is used for mushroom cultivation and the subsequent recovery of the spent substrate for tomato germination.
（龙舌兰普尔克酒用龙舌兰）的蔗渣是在利用该植物获取普尔克酒、菊粉、蜂蜜等过程中产生的一种残渣。由于其化学成分，它可用于培养某属真菌，随后将降解后的物质“降解基质（DS）”用作蔬菜发芽的支撑物。本研究的目的是将经某菌降解的龙舌兰普尔克酒蔗渣作为其价值链中的一个新视角进行表征，并随后用于番茄发芽。在培养60天后从某菌培养物中回收DS，对其进行理化特性表征，并通过扫描电子显微镜观察植物组织的形态。DS的蛋白质含量（从4.8%降至3.3%）和纤维部分（从54%降至36%）减少，但干物质消化率从47%提高到71%；此外，观察到矿物质组成发生变化，主要是钙浓度（6%）。由于其组成，有可能在番茄发芽过程中重新利用DS以减少泥炭藓（商业泥炭）的使用。结果表明，高达25%的龙舌兰DS与75%的泥炭藓混合使用（25:75），发芽率可达85%，并使幼苗出土速度指数从0.96提高到1.25。结论是有可能实施一种循环策略，即利用龙舌兰蔗渣进行蘑菇栽培，随后回收用过的基质用于番茄发芽。
