colonies were grown on different supports for the removal of nitrates from water. A carbon material and different commercial metal oxides, such as SiO, TiO and AlO, and their corresponding carbon-metal oxide composites were studied. The physicochemical properties were analyzed by different techniques and the results were correlated with their performance in the denitrification process. Developed biofilms effectively adhere to the supports and always reach the complete reduction of nitrates to gaseous products. Nevertheless, faster processes occur when the biofilm is supported on mesoporous and non-acid materials (carbon and silica).
将菌落培养在不同载体上以去除水中的硝酸盐。研究了一种碳材料、不同的商业金属氧化物，如二氧化硅、二氧化钛和氧化铝，以及它们相应的碳 - 金属氧化物复合材料。通过不同技术分析了其物理化学性质，并将结果与它们在反硝化过程中的性能相关联。所形成的生物膜能有效附着在载体上，并总能将硝酸盐完全还原为气态产物。然而，当生物膜负载在中孔和非酸性材料（碳和二氧化硅）上时，反应进程更快。
