“…This result was likely because species affiliated to these families, frequently isolated from wastewater treatment plants, were introduced by sewage sludge into mudflat soil and favored the growth by the amended physicochemical properties therein. It is worth noting that abundant members belonging to the families mentioned above have been widely demonstrated to be associated with carbon substrate utilization and nitrogen related functions in soils, strongly implying the improvement of mudflat soil functional capabilities induced by sewage sludge amendment [ 69 , 70 , 71 , 72 , 73 ]. Regarding unique microbiomes, distinct profiles of bacterial communities were observed across four treatments, and the profiles were dramatically different from the soil core bacterial communities ( Figure 3 B), indicating that the unique microbiome in mudflat soil more relied on the sewage sludge application.…”

The study investigated the influence of sewage sludge application at rates of 0 (CK), 30 (ST), 75 (MT), and 150 (HT) t ha−1 to mudflats on bacterial community diversity and predicted functions using amplicon-based sequencing. Soils under sewage sludge treatments, especially the HT treatment, exhibited lower pH, salinity and higher nutrient contents (C, N, and P). Moreover, restructured bacterial communities with significantly higher diversities and distinct core and unique microbiomes were observed in all sewage sludge-amended soils as compared to the control. Specifically, core bacterial families, such as Hyphomicrobiaceae, Cytophagaceae, Pirellulaceae Microbacteriaceae, and Phyllobacteriaceae, were significantly enriched in sewage sludge-amended soils. In addition, sewage sludge amendment significantly improved predicted functional diversities of core microbiomes, with significantly higher accumulative relative abundances of functions related to carbon and nitrogen cycling processes compared to the unamended treatment. Correlation analyses showed that modified soil physicochemical properties were conducive for the improvement of diversities of bacterial communities and predicted functionalities. These outcomes demonstrated that sewage sludge amendment not only alleviated saline–sodic and nutrient deficiency conditions, but also restructured bacterial communities with higher diversities and versatile functions, which may be particularly important for the fertility formation and development of mudflat soils.
