This data describes the supplementary materials (additional Figures, and Tables) for the article https://doi.org/10.1016/j.jenvman.2020.111252 Thermoacidophilic effective microbes (tEM) were used to enhance the composting process of lignocellulosic waste. Composting with tEM slightly reduced NH3 emission during the composting process while CH4, and CO2 patterns positively correspond to the rate of composting, with higher emissions in tEM treatment during 60d – 90d composting. Compost microbial evolution based metagenomic DNA sequencing and culture-based microbial enumeration indicate higher abundance and diversity of microbes in tEM treated groups especially at thermophilic temperatures. Chemical analysis showed higher rate of mineralization in tEM treated compost compared to control group while the heavy metal content was below the international threshold levels in both treatment and control. Moreover, germination index (Gi) and global germination index (GI) were higher in tEM treated compost compared to control group. The data is important for evaluating composting efficiency and quality of the final compost product.

本数据集对应期刊论文https://doi.org/10.1016/j.jenvman.2020.111252的补充材料（含附加图表与表格）。该研究采用嗜热嗜酸功能微生物（Thermoacidophilic Effective Microbes，tEM）强化木质纤维素类废弃物的堆肥工艺。采用tEM进行堆肥可小幅降低堆肥过程中的氨（NH3）排放；而甲烷（CH4）与二氧化碳（CO2）的排放规律与堆肥速率呈正相关，在堆肥60至90天阶段，tEM处理组的排放水平更高。基于宏基因组DNA测序与培养法微生物计数的堆肥微生物演化分析结果显示，tEM处理组的微生物丰度与多样性更高，尤其在堆肥高温阶段。化学分析结果表明，相较于对照组，tEM处理组堆肥的矿化速率更高；且处理组与对照组的重金属含量均低于国际阈值标准。此外，tEM处理组堆肥的发芽指数（Germination Index，Gi）与总发芽指数（Global Germination Index，GI）均高于对照组。本数据集可为堆肥效率与最终堆肥产品的质量评估提供重要支撑。

背景概述

该数据集是学术文章《Thermoacidophilic effective microbes (tEM) were used to enhance the composting process of lignocellulosic waste》的补充材料，内容包括额外的图表和数据。数据集展示了使用嗜热酸性有效微生物（tEM）增强木质纤维素废物堆肥过程的效果：tEM处理略微减少NH3排放，提高微生物丰度和多样性，加速矿化速率，并改善堆肥质量（如发芽指数更高），同时重金属含量低于安全阈值。这些数据对于评估堆肥效率和最终产品质量至关重要。
