The purposes of this study was to evaluate the ability of Aspergillus niger and Rhizopus oligosporus for one-step bioleaching of Cu and Pb in printed circuit boards (PCBs) scrap from e-waste recycling shops, compared to acidic extraction with citric and lactic acids. The fungal spore suspension was cultivated in potato dextrose broth with dried PCBs and a shaker for 42 days. Every 7 days the leachates were analyzed for Cu and Pb concentrations using atomic absorption spectroscopy. The Cu and Pb concentrations in PCBs in e-waste recycling shops were 152.81 ± 26.54 and 25.62 ± 8.33 g kg–1 PCBs, respectively. The leaching experiment showed that 0.05 M citric acid was the most efficient leaching pure acid: more than 54.59% of Cu and 79.55% of Pb was released into solution. Heavy metal leaching by the lactic acid was less efficient. The best metal bioleaching efficiency was achieved by A. niger fungus, which extracted approximately 46.92% of Cu, and almost 30.63% of Pb from PCBs. R. oligosporus leached only 8.53 and 19.61% of Cu and Pb, respectively.
本研究的目的是评估黑曲霉和少孢根霉对电子垃圾回收店印刷电路板(pcb)废料中铜和铅的一步生物浸出能力，并与柠檬酸和乳酸酸提取进行比较。将真菌孢子悬浮液与干燥的多氯联苯和摇床一起在马铃薯葡萄糖肉汤中培养42 d。每隔7天用原子吸收光谱分析渗滤液中Cu和Pb的浓度。电子垃圾回收站多氯联苯中Cu和Pb浓度分别为152.81±26.54和25.62±8.33 g kg-1 PCBs。浸出实验表明，0.05 M柠檬酸是最有效的浸出纯酸，Cu和Pb的释放量分别超过54.59%和79.55%。乳酸对重金属的浸出效率较低。黑曲霉的金属浸出效果最好，铜和铅的浸出率分别为46.92%和30.63%。少孢霉对Cu和Pb的浸出率分别为8.53%和19.61%。

Feeding with the telia structures of an exotic fungus species Gymnosporangium sabinae (Dicks.) G. Winter (1884) (Basidiomycota: Pucciniaceae) by the native snail species, Trochulus hispidus (Linnaeus, 1758) (Gastropoda: Hygromiidae), was documented in spring of 2015 and 2016 in Latvia. In both years snails fed with G. sabinae in field conditions at a home garden at Dobele (Latvia). T. hispidus generally preferred initial structures of G. sabinae telia before these structures developed as orange gelatinous mass, when fungus lost its attraction as potential food for T. hispidus snails.
