“…Benthic diatoms, such as Nitzschia Hass., may be used to manage the rate of N and P released from the sediment to reduce nutrient pollution from aquaculture (Xing et al, 2019). By studying the growth and nutrient removal of periphyton in a shallow, eutrophic lake, Ma, Chen, Lu, and Liao (2019) determined the nutrient removal capacity per unit area of periphyton is 1.23 × 10 −5 g total N m −2 day −1 and 2.46 × 10 −5 g total P m −2 day −1 . Yi, Yang, Yan, and Pei (2019) observed periphyton (by its absorption, filtration, and precipitation of nutrients) acting as biological buffers for nutrient cycling, with periphyton's extent of influence closely related to sediment nutrient levels.…”

Highlights of new, interesting, and emerging research findings on substratum-associated microbiota covered from a survey of 2019 literature from primarily freshwaters provide insight into research trends of interest to the Water Environment Federation and others interested in benthic, aquatic environments. Coverage of topics on bottom-associated or attached algae and cyanobacteria, though not comprehensive, includes new methods, taxa new-to-science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, and bloom-forming and harmful algae. Coverage of bacteria, also not comprehensive, focuses on the ecology of benthic biofilms and microbial communities, along with the ecology of microbes like Caulobacter crescentus, Rhodobacter, and other freshwater microbial species. Bacterial topics covered also include metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. Readers may use this literature review to learn about or renew their interest in the recent advances and discoveries regarding substratum-associated microbiota. © 2020 Water Environment Federation • Practitioner points • This review of literature from 2019 on substratum-associated microbiota presents highlights of findings on algae, cyanobacteria, and bacteria from primarily freshwaters. • Coverage of algae and cyanobacteria includes findings on new methods, taxa new to science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, bloomforming and harmful algae. • Coverage of bacteria includes findings on ecology of benthic biofilms and microbial communities, the ecology of microbes, metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. • Highlights of new, noteworthy and emerging topics build on those from 2018 and will be of relevance to the Water Environment Federation and others interested in benthic, aquatic environments

“…Biofilms drive several material cycling and energy flow pathways and thus, play important roles in environmental restoration [7]. ES has been installed in diverse ecosystems, including rivers [8], lakes [9], and reservoirs [10] and has wide functions in increasing hydraulic retention time, tuning the delivery of nutrients, mediating the fate of pollutants, which make great contributions to the self-purification of aquatic ecosystems [11]. To manage the environmental degradation issue caused by the intensive aquaculture, the ES has been utilized in aquaculture systems, including Litopenaeus vannamei aquaculture systems [12], Penaeus monodon aquaculture systems [13], and Oncorhynchus mykiss aquaculture systems [14], etc.…”

Aquaculture supplies high-quality and healthy proteins. With the increasing human demand for aquaculture production, intensive pond aquaculture developed rapidly and results in environmental deterioration. To solve this problem, the eco-substrate (ES), which is the biofilm carrier, has been utilized in aquaculture ponds. Studying the ecological mechanisms of ES from the perspective of the ecosystem may be conducive to the sustainable development of aquaculture. In this study, it was evaluated how ES makes a difference to the trophic structure, energy flow, and system characteristics of two different aquaculture pond ecosystems via the ecopath model. Three aquaculture ponds with ES were designed as the treatment ecosystem and three aquaculture ponds without ES were designed as the control ecosystem. There were 13 and 14 functional groups in the control and treatment ecosystems, respectively. The results showed that (1) the macrozooplankton and microzooplankton showed strong effects on the ecosystem in the keystoneness index; (2) energy transfer pathways in the treatment system with ES increased by 26.23% compared to the control system; (3) the ES improved the utilization rate of detritus, which was 14.91% higher than that of the control ecosystem; (4) the material and energy flow index and network information characteristics demonstrated the ES enhanced the complexity and stability of the treatment system. To improve the energy utilization efficiency, filter feeders can be introduced to ES ponds. Overall, the ES can alter the trophic structure, improve the energy utilization efficiency, and enhance the stability and maturity of aquaculture ecosystems, representing a sustainable practice. Considering the total area of aquaculture ponds on the earth reaching more than 5 million hectares, the application prospect of ES is broad.

“…Periphyton, consisting of bacteria, fungi, algae, and other microbes, are microbial aggregates growing on submerged substrate surfaces (Battin et al, 2016; Tlili et al, 2017). As the main primary producer, periphyton plays a pivotal role in the biogeochemical cycle in aquatic systems (Battin et al, 2016), and is susceptible to changes in a variety of environmental stressors, especially water quality variables, such as temperature (Bondar‐Kunze et al, 2021), nutrients (Ma et al, 2019), and salinity (Cochero et al, 2017). Owing to rapid community succession, periphyton tends to adapt to these external stressors by altering its community structure (Larned, 2010).…”

1. Periphyton in aquatic ecosystems play a crucial ecological role in element cycling and are susceptible to natural disturbances and anthropogenic activities.To understand the responses of periphytic communities to water quality factors and altitude gradients, DNA metabarcoding was employed to investigate the distribution characteristics of epilithic periphyton (comprising prokaryotes and eukaryotes).2. Epilithic periphyton and water were sampled at 26 sampling sites with an altitude ranging from 445 to 1,565 m in the Jue River and its three tributaries in Qinling Mountain, China. The altitudinal patterns of water quality variables were initially investigated, followed by redundancy analysis and distance-based linear models to explore the responses of community structure to altitudes and water quality. Meanwhile, the relationship between these variables and fluorescence parameters to reflect the photosynthesis of epilithic periphyton along an altitudinal gradient was examined.3. The results indicated that with decreasing elevation, water quality variables including total dissolved solids (TDS), water temperature, conductivity, salinity, and concentrations of NO − 3 -N, total nitrogen, and NO − 2 -N increased. This pattern was closely associated with the intensification of anthropogenic disturbance downstream. Specifically, higher salinity and water temperature downstream may reduce the prokaryotic biodiversity but promote the diversity and evenness of eukaryotes; higher concentrations of total nitrogen may increase the diversity, richness, and evenness of the whole periphyton community. Furthermore, salinity, nutrients, and TDS were identified as crucial variables shaping periphyton community structure, especially salinity and TDS, which were linked to the growth of chlorophytes.4. The attenuated maximum photochemical efficiency of periphyton at high altitudes indicated that photosystem II was inhibited, while the enhancement of maximum photochemical efficiency at low altitudes may be attributed to the
