“…Nitrogen fixation, ammoniation, nitrification and denitrification in nature are all inseparable from the participation of microorganisms [63]. Other studies found that phosphate was the main environmental factor influencing the structure of the bacterial community in surface water, such as reservoirs [56] and rivers [64], because bacteria can assimilate phosphate through the cell membranes to meet their need for phosphorus [65]. No specific relationship caused by the environmental factors was found between natural water and reclaimed water in this study.…”

“…The dominant microbes of natural biofilms collected in the river channel on the first day (NF) were Firmicutes (38.61%), Actinobacteria (20.69%), Proteobacteria (18.27%), Bacteroidetes (14.74%) and Cyanobacteria (4.95%) ( Figure 4a). There are few reports about Firmicutes as the most dominant phylum in biofilms, and a high relative abundance of Firmicutes is usually detected in wastewater [56]. This may indicate that the water or biofilm may be contaminated.…”

Using reclaimed water as a resource for landscape water replenishment may alleviate the major problems of water resource shortages and water environment pollution. However, the safety of the reclaimed water and the risk of eutrophication caused by the reclaimed water replenishment are unclear to the public and to the research community. This study aimed to reveal the differences between natural water and reclaimed water and to discuss the rationality of reclaimed water replenishment from the perspective of microorganisms. The microbial community structures in natural water, reclaimed water and natural biofilms were analyzed, and the community succession was clarified along the ecological niches, water resources, fluidity and time using 16S rRNA gene amplicon sequencing. Primary biofilms without the original community were added to study the formation of microbial community structures under reclaimed water acclimation. The results showed that the difference caused by ecological niches was more than those caused by the fluidity of water and different water resources. No significant difference caused by the addition of reclaimed water was found in the microbial diversity and community structure. Based on the results of microbial analysis, reclaimed water replenishment is a feasible solution that can be used for supplying river water.

“…These findings indicate that the environmental factors change with the change in breeding cycle, which affects the growth and living environment of the turtle [74,75]. These findings also explain that the microbial composition and abundance of water are closely related to water quality indicators [25,76].…”

“…Meanwhile, with the continuous expanding of environmentally microbial research, the high-throughput 16S rRNA gene amplicon sequencing was widely used for understanding the effects of a variety of environments on the microbes and also helps to profile complex microbial communities and the diversity of bacterial structure and function with the significant reduction in sequencing costs, which results in a surge of microbial sequencing researches [ 14 , 15 , 16 , 17 , 18 , 19 ]. The aquaculture systems are complex and easily affected by natural environment and human factors [ 20 , 21 , 22 ], and the microbial diversity is greatly affected by aquaculture water quality factors [ 23 ], for example, the ammonia nitrogen (AN) and total nitrogen (TN) contents had a great influence on the bacterial communities of Litopenaeus vannamei culture ponds [ 24 , 25 ]. Hence, the water quality factors, aquatic microorganisms, and the health of aquatic product are closely related to each other.…”

A First Insight into the Structural and Functional Comparison of Environmental Microbiota in Freshwater Turtle Chinemys reevesii at Different Growth Stages under Pond and Greenhouse Cultivation

The microbial community structure of water is an important indicator for evaluating the water quality of the aquaculture environment. In this study, the investigation and comparison of the bacterial communities of pond cultivation (PC) and greenhouse cultivation (GC) between hatchling, juvenile, and adult growth stages of C. reevesii were performed. In addition, the V4 regions of the 16S rRNA gene were sequenced. The Chao1 richness estimator of the PC group was significantly higher than that of the GC group. The beta diversity showed that the microbiotas of the two groups were isolated from each other. The dominant phyla were Cyanobacteria, Proteobacteria, Actinobacteria, Bacteroidetes, Verrucomicrobia, and Planctomycetes in the PC group and Proteobacteria, Bacteroidetes, Firmicutes, Cyanobacteria, Chloroflexi, and Actinobacteria in the GC group. Both the numbers and the types of Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway annotations differed between the PC and GC groups. The prediction of bacterial phenotype implied that the GC environment is more likely to deteriorate, and turtles are more susceptible to pathogens than those of the PC environment. In addition, a total of nine potential pathogenic bacteria were identified and the correlation of environmental factors analyses showed significant differences of bacterial species between the PC and GC groups, while the potential pathogenic bacteria showed significant correlation with the stocking density, temperature, pH, orthophosphate (PO4-P), and dissolved oxygen (DO) in both the PC and GC groups. Noticeably, this is the first report to describe the different microbiota characteristics of the different cultivation environments in the different growth stages of C. reevesii, which will provide valuable data for water quality adjustment, disease prevention, and the healthy breeding of turtles.

The microbial community structure is an important indicator for evaluating the water quality of the aquaculture environment. In this study, V4 regions of 16S rRNA gene of pond (PC) and greenhouse cultured (GC) C. reevesii were sequenced. Results showed that a total of 1,993,090 high quality counts and 105,159 observed OUTs were obtained; and the Chao1 richness estimator of PC was significantly higher than that of GC groups. Beta-diversity showed that the microbiota of two groups were isolated from each other. In addition, the correlation analysis of environmental factors showed that NO2-N, PH, PO4-P, and stocking density played significant roles in the bacterial community composition. The dominant phyla in PC groups were cyanobacteria, proteobacteria, actinobacteria, bacteroidetes, verrucomicrobia, planctomycetes; and in GC groups were proteobacteria, bacteroidetes, firmicutes, cyanobacteria, chloroﬂexi, actinobacteria. The functional prediction showed that the top5 Picrust prediction gene functions were protein processing in endoplasmic reticulum, retinol metabolism, proteasome, glycan binding proteins, and stilbenoid, diarylheptanoid and gingerol biosynthesis. Meanwhile, the numbers and types of KEGG pathway annotations showed a significant difference between the two cultivation environments. The prediction of bacterial phenotype implied that the GC environment is more likely to deteriorate, and turtles are more susceptible to pathogens than those of PC environment. This is the first report to explore and understand the difference of microbiota characteristics between different cultivation environments in different growth stages of C. reevesii, which will provide basic data for water quality adjustment, disease prevention, and healthy breeding of turtle.
