The key limiting factors in the treatment of low C/N micropolluted water bodies are deficient essential electron donors for nitrogen removal processes. An iron/activated carbon aquagel (IACA) was synthesized as a slowly released inorganic donor to enhance aerobic denitrification performance treatment. efficiency IACA reactors enhanced by more than 56.72% and highest 94.12% accomplished compared with those control reactors. Moreover, CODMn improved 34.32% Illumina MiSeq sequencing consequence explained that denitrifying bacteria facultative denitrification, iron oxidation, reduction function were located dominant species niches (e.g., Pseudomonas, Leptothrix, Comamonas). diversity richness bacterial communities Network analysis indicated consortia presented complicated co-occurrence structure. potential long-term operation. This study affords pathway utilize IACA, promoting during body

The coculture theory that promotes denitrification relies on effectively utilizing the resources of low-efficiency microbes. Here, strains Streptomyces sp. PYX97 and TSJ96 were isolated showed lower capacity when cultured individually. However, enhanced nitrogen removal (removed 96.40% total nitrogen) organic carbon reduction 92.13% dissolved carbon) under aerobic conditions. Nitrogen balance analysis indicated coculturing efficiency nitrate converted into gaseous reaching 70.42%. Meanwhile, promoted cell metabolism source metabolic activity. thrived in conditions C/N = 10, alkalescence, 150 rpm shaking speed. reduced CODMn raw water treatment by 83.32 84.21%, respectively. During this treatment, activity density increased reactor. Moreover, could utilize aromatic protein soluble microbial products during processes treatment. This study suggests inefficient actinomycete be a promising approach for treating polluted bodies.
