“…Thus, pioneer species may actively change their environment (i.e. biofilm formation) to facilitate the invasion of new species that would otherwise not survive and/or thrive [ 30 ]. This study showed that Alphaproteobacteria and Gammaproteobacteria were the main prokaryotic colonizer species in the early plastisphere, which have also been recognized as pioneer colonizers of the plastisphere in aquatic environments [ 37 , 38 ].…”

“…Then, the beta-diversity of the plastisphere prokaryotic and eukaryotic communities was partitioned into two components (species turnover and nestedness) using the “betapart” R package [ 29 ]. Specifically, β ratio = β sim /β SOR , β ratio > 0.5 indicates that beta diversity was determined dominantly by species turnover, and β ratio < 0.5 indicates that nestedness was the dominant driver [ 30 ]. To reveal the rate of temporal turnover of the plastisphere prokaryotic and eukaryotic communities, the distance–decay relationship was investigated using the Sørensen similarity of microbial communities and change in Euclidean distance with colonization time [ 31 ].…”

Succession is a fundamental aspect of ecological theory, but studies on temporal succession trajectories and ecological driving mechanisms of plastisphere microbial communities across diverse colonization environments remain scarce and poorly understood. To fill this knowledge gap, we assessed the primary colonizers, succession trajectories, assembly, and turnover mechanisms of plastisphere prokaryotes and eukaryotes from four freshwater lakes. Our results show that differences in microbial composition similarity, temporal turnover rate, and assembly processes in the plastisphere do not exclusively occur at the kingdom level (prokaryotes and eukaryotes), but also depend on environmental conditions and colonization time. Thereby, the time of plastisphere colonization has a stronger impact on community composition and assembly of prokaryotes than eukaryoties, whereas for environmental conditions the opposite pattern holds true. Across all lakes, deterministic processes shaped the assembly of the prokaryotes, but stochastic processes that of the eukaryotes. Yet, they share similar assembly processes throughout the temporal succession: Species turnover over time causes the loss of any priority effect, which leads to a convergent succession of plastisphere microbial communities. The increase and loss of microbial diversity in different kingdoms during succession in the plastisphere potentially impacts the stability of entire microbial communities and related biogeochemical cycles. Therefore, research needs to integrate temporal dynamics along with spatial turnovers of the plastisphere microbiome. Taking the heterogeneity of global lakes and the diversity of global climate patterns into account, we highlight the urgency to investigate the spatiotemporal succession mechanism of plastisphere prokaryotes and eukaryotes in more lakes around the world.

“…One of the problems is how to maintain a stable operation under the increasing nitrogen substrate concentration [5]. Biofilm has a good tolerance for the fluctuating cultural environment [6][7][8][9]. There are many related studies on anammox fillers [10][11][12][13], but few related studies on the comparison of different anammox fillers in different substrate ratios and concentrations.…”

The article investigated the effect of substrate ratio and shock load resistance on the nitrogen removal efficiency of curtain packing anammox filler and bundle packing anammox filler. The results had shown that the nitrogen removal performance was recommendable when the NH4 +-N: NO2 −-N was set as 1:1.20, regardless of the curtain packing filler or the bundle packing filler. After the total nitrogen concentration was directly increased from 770 mg/L to 1320 mg/L for 12 h. From the perspective of the steady of nitrogen removal performance, the bundle packing filler was better than curtain packing filler, and the effluent TN concentration was beyond 70 mg/L. Subsequently, within 1 day when the influent TN concentration increased to 770 mg/L, both filler systems quickly recovered. The structure of the bundle packing was beneficial to the fixed, cultured, and aggregation of anammox bacteria made it a better filler type. The high-throughput results showed that the dominant bacteria in the two packing fillers was Candidatus Kuenenia, which accounted for 15.16% and 22.85% in the curtain packing filler and the bundle packing filler system respectively.
