The substrate mixtures were created in the study, using spent coffee grounds for Pleurotus ostreatus cultivation with the addition of straw and fluidized bed ash at 5 and 10 percent by weight relative to the total weight of coffee grounds. In order to determine the ability to accumulate heavy metals and the possibility of further waste management, analyses of micro- and macronutrients, biogenic elements, as well as the metal content of fungal fruiting bodies, mycelium and post-cultivation substrate were performed. The addition of 5 percent resulted in slower growth of mycelium and fruiting bodies, and with the addition of 10 percent, the growth of fruiting bodies was completely inhibited. The accumulation of elements such as (Cr), (Cu), (Ni), (Pb) and (Zn) was reduced in the fruiting bodies grown on the substrate with the addition of 5 percent fly ash, compared to spent coffee grounds without additives.
研究中使用咖啡渣作为糙皮侧耳（Pleurotus ostreatus）的栽培基质，添加 5%和 10%（相对于咖啡渣总重量）的秸秆和流化床灰分，以创建基质混合物。为了确定积累重金属的能力和进一步废物管理的可能性，对微生物和宏量营养素、生物元素以及真菌子实体、菌丝体和培养后基质中的金属含量进行了分析。添加 5%导致菌丝体和子实体生长缓慢，添加 10%时，子实体的生长完全受到抑制。与未添加添加剂的咖啡渣相比，在添加 5%飞灰的基质上生长的子实体中，（Cr）、（Cu）、（Ni）、（Pb）和（Zn）等元素的积累减少。
