“…For instance, Proteobacteria play an important role in carbon metabolism [ 34 ], decompose soluble sugars [ 35 ] and can be influenced by humic-like DOM [ 36 ]. Actinobacteria play important roles in decomposing organic carbon for lake water quality [ 37 , 38 ] and were reported to be strongly affected by humic-like DOM [ 36 ]; Bacteroidetes are mainly responsible for carbon metabolism, including decomposing hydrolytic cellulose [ 39 ] and remineralising complex and labile DOM [ 40 ]. Cyanobacteria typically act as the dominant primary producers of DOM [ 41 ].…”

The relationship between CDOM (Chromophoric dissolved organic matter) and the bacterial community was investigated in ice-covered Baiyangdian Lake. The results showed that environmental parameters significantly differed in Baiyangdian Lake, whereas a-diversity was not significantly different. Moreover, the microbial and functional communities exhibited significant differences, and T (Temperature), pH, ORP (Oxidation-reduction potential), DO (Dissolved oxygen), NO3−-N, NH4+-N, and Mn (Manganese) were the main environmental factors of these differences, based on redundancy analysis and the Mantel test. Biomarkers of the microbial and functional communities were investigated through linear discriminant analysis effect size and STAMP analysis. The number of biomarkers in the natural area was highest among the typical zones, and most top functions were related to carbohydrate metabolism. Two protein-like components (C1 and C2) and one humic-like component (C3) were identified by parallel factor analysis, and C1 was positively related to C2 (R = 0.99, p < 0.001), indicating the same sources. Moreover, CDOM significantly differed among the typical zones (p < 0.001). The high biological index, fluorescence index, β:α, and low humification index indicated a strong autochthonous component and aquatic bacterial origin, which was consistent with the results of UV-vis absorption spectroscopy. Network analysis revealed non-random co-occurrence patterns. The bacterial and functional communities interacted closely with CDOM. The dominant genera were CL500-29_marine_group, Flavobacterium, Limnohabitans, and Candidatus_Aquirestis. Random forest analysis showed that C1, C2, and C3 are important predictors of α- and β-diversity in the water bacterial community and its functional composition. This study provides insight into the interaction between bacterial communities and DOM (Dissolved organic matter) in ice-covered Baiyangdian Lake.

“…Several attempts have been tested for bioremediation of waste. This included the use of cyanobacterial mats for bioremediation of chemical wastes [5]- [11], use of sand filter [12], land fills [13], incineration of wastes [14] and composting of organic wastes [15]. So far, the cyanobacteria were able to use the organic pollutants as a source of carbon, whereas sand filter was able to reduce biological and chemical oxygen demand for wastewater and provided good quality wastewater.…”

This study investigated the effect of biogas production on the removal hazardous waste properties. Biogas was produced from caw, chicken and mixed manure. Samples were taken before and after biogas production and tested for removal of total solid (TS), removal of chemical oxygen demand (COD), biological oxygen demand (BOD), and fecal coliform bacteria (FC). Results showed tremendous removal of the above mentioned parameters after biogas production. Chemical analysis of digestate indicates the advantages of using them as plant nutrients. Application of digestate in soil dramatically changed the chemical and physical properties of soil. It can be concluded that biogas production, is not only producing biogas but also removing waste parameters (TS, COD, BOD, FC) and producing plant nutrients.

“…Proteobacteria and Chloroflexi were detected as the main dominant phyla with a high frequency for wastewater treatment [33][34]. Proteobacteria could be related to the removal of various organic matters from wastewater [35]. Meanwhile, Proteobacteria has the function of nitrogen and phosphorus removal, such as Nitrosomonas and Nitrosococcus genus in AOB, and Nitrobacter and Nitrococcu in NOB all belong to Proteobacteria phyla [36][37].…”

“…Namely, the surface layer contained more Actinobacteria and Bacteroidetes. Actinobacteria [35] and Bacteroidetes [39] mainly existed in the place where the organism is concentrated. The influent of the CRI was from the upper part uniformly, so the organism concentration on the surface was the highest, which caused the abundances of Actinobacteria and Bacteroidetes to be higher.…”

To study the removal performance of a constructed rapid infiltration (CRI) system and its microbial community characteristics, we took the demonstration project of a CRI system that has successfully operated for 15 years as an example, aiming to analyze the CRI system's removal performances for COD, NH 4 +-N, TN and TP. Meanwhile, high-throughput sequencing technology was used for the first time to study the microbial community diversity and structure in the CRI system. The results showed that the average removal efficiencies for COD and NH 4 +-N were 75.52% and 92.94%, and the average removal efficiencies for TN and TP were respectively 39.74% and 42.78%. High-throughput sequencing technology indicated that a variety of bacterial phyla were found in CRI's bacterial communities, including Bacteroidetes, Actinobacteria and Acidobacteria, among which Proteobacteria dominated. At the genus level, a spatial variation was illustrated for the diversity and structure of bacterial communities. The dominant genera on the surface layer (0 cm) of CRI were mainly Nocardioides, Sphingomonas, Bryobacter and other microorganisms that can degrade organic matter, and the dominant genera in the inside (30-120 cm) were mainly microorganisms that play an important role in removing nitrogen. This study provided a theoretical basis for the long-term operation of a CRI system.
