In this work, carbonized quinoa starch (CQS) was incorporated in the growth of the fungal hyphae (FH) of Aspergillus niger (AN) and Myrothecium verrucaria (MV), to form FH/CQS composites through a biological self-assembly method. The two hyphae/starch porous carbon materials (PCCQS-AN and PCCQS-MV) were successfully prepared using the FH/CQS as templates. The characterization results showed that PCCQS-AN and PCCQS-MV had higher specific surface areas and pore volumes than the quinoa starch-based porous carbon (PCQS). Adsorption experiments involving a synthetic dye, Rhodamine B (RhB), and an antibiotic, tetracycline hydrochloride (TCH), as model pollutants revealed that the adsorption capacities of PCCQS-AN and PCCQS-MV were higher than those of PCQS. In addition, the removal rates of RhB and TCH by PCCQS-AN and PCCQS-MV remained above 50% after 5 cycles, which were higher than that of PCQS. This study proves that the biological self-assembly approach is an advanced method, and provides a new feasible direction for the research and development of other microorganism composites.

生物自组装菌丝/淀粉多孔碳复合材料去除水中有机污染物

在这项工作中,碳化藜麦淀粉 (CQS) 被纳入黑曲霉(AN) 和疣状菌丝 ( Myrothecium v​​errucaria ) 真菌菌丝 (FH) 的生长中。(MV),通过生物自组装方法形成 FH/CQS 复合材料。以 FH/CQS 为模板成功制备了两种菌丝/淀粉多孔碳材料(PCCQS-AN 和 PCCQS-MV)。表征结果表明,PCCQS-AN 和 PCCQS-MV 比藜麦淀粉基多孔碳 (PCQS) 具有更高的比表面积和孔体积。涉及合成染料罗丹明 B (RhB) 和抗生素盐酸四环素 (TCH) 作为模型污染物的吸附实验表明,PCCQS-AN 和 PCCQS-MV 的吸附能力高于 PCQS。此外,PCCQS-AN 和 PCCQS-MV 对 RhB 和 TCH 的去除率在 5 个循环后保持在 50% 以上,高于 PCQS。这项研究证明了生物自组装方法是一种先进的方法,
