“…An analysis of urban soils from the street green belts of the city of Chicago, USA, revealed that soils along a one‐way street showed higher Shannon and phylogenetic diversities than other soils, including those along a two‐way street, a feature that could be correlated with soil pH, moisture and texture (Wang et al ., ). We believe that the microorganisms living in the street, in street gutters and on pedestrian surfaces may present specific surface‐associated diversity, such as the ones identified on concrete (Domingo et al ., ; Li et al ., ; Gomez‐Alvarez et al ., ; Jiang et al ., ; Cayford et al ., ; Cowle et al ., ; Li et al ., ) or buildings and monuments (Ragon et al ., ; Chimienti et al ., ; Gaylarde et al ., ; Adamiak et al ., ; Dyda et al ., ).…”

Summary Streets are constantly crossed by billions of vehicles and pedestrians. Their gutters, which convey stormwater and contribute to waste management, and are important for human health and well‐being, probably play a number of ecological roles. Street surfaces may also represent an important part of city surface areas. To better characterize the ecology of this yet poorly explored compartment, we used filtration and DNA metabarcoding to address microbial community composition and assembly across the city of Paris, France. Diverse bacterial and eukaryotic taxonomic groups were identified, including members involved in key biogeochemical processes, along with a number of parasites and putative pathogens of human, animals and plants. We showed that the beta diversity patterns between bacterial and eukaryotic communities were correlated, suggesting interdomain associations. Beta diversity analyses revealed the significance of biotic factors (cohesion metrics) in shaping gutter microbial community assembly and, to a lesser extent, the contribution of abiotic factors (pH and conductivity). Co‐occurrences analysis confirmed contrasting non‐random patterns both within and between domains of life, specifically when comparing diatoms and fungi. Our results highlight microbial coexistence patterns in streets and reinforce the need to further explore biodiversity in urban ground transportation infrastructures.

The pollution release and the anti-scourability characteristics of the pipe sewage sediments can directly determine the blockage status of pipeline and treatment burden at the terminal (sewage treatment plant). In this study, the sewer environment under different buried depths was designed to explore the impact of incubation time on the physicochemical characteristics, pollution release effect and anti-scouring ability of the silted sediment in the drainage pipe. The results show that, incubation time, sediment matrix, temperature and dissolved oxygen can affect microbial activity, but temperature has a greater in uence.These factors affect microbial activity and loosen the superstructure in the sediment. In addition, by measuring the indexes of nitrogen and phosphorus in the overlying water, it was found that the sediment incubated for a certain time can release pollutants to the overlying water, and the release amount was obviously affected by high temperature (e.g., 35 ℃). After a certain time (e.g., 30 days), bio lms appear on the sediment surface, and the anti-scourability of sediment was signi cantly improved, which was re ected in the increase of the median particle size of sediment left in the pipe.
