Abstract：
The safe management of sewage waste is a current concern due to population growth and waste production. Biosolids, derived from sewage sludge treatment, are globally used as organic fertilizers, aligning with Sustainable Development Goal 6 for resource recycling. However, biosafety concerns arise due to the presence of metals and microplastics in biosolids, potentially impacting soil and water. This study investigated biosolids\' use for in vitro cultivation of Bowdichia virgilioides Kunth. Results indicate that while biosolids can replace traditional nutritional media, balancing their concentration is crucial for optimizing plant growth. The WPM (Wood Plat Medium) remains essential for in vitro cultivation, but substituting it with biosolids at concentrations of up to 2 g L- 1 is feasible, providing similar plant development compared to the WPM medium. However, when combined, there is a complex and challenging interaction between biosolids and the culture medium.
摘要：
由于人口增长和废物产生，污水废物的安全管理是当前关注的问题。生物固体,来自污水污泥处理，在全球范围内用作有机肥料，与资源回收的可持续发展目标6保持一致。然而,由于生物固体中金属和微塑料的存在，生物安全问题引起了人们的关注，可能影响土壤和水。这项研究调查了生物固体在体外培养中的用途。结果表明，虽然生物固体可以替代传统的营养培养基，平衡它们的浓度对于优化植物生长至关重要。WPM（木纹培养基）对于体外培养仍然是必不可少的，但是用浓度高达2gL-1的生物固体代替它是可行的，与WPM培养基相比提供相似的植物发育。然而,当合并时，生物固体和培养基之间存在复杂且具有挑战性的相互作用。
