“…The microorganisms have been used to convert dissolved organic matter into harmless substances, and the commercial micro-ecological products include effective microorganisms (EM), Bacillus, Streptococcus, Lactobacillus, and photosynthetic bacteria ( Kuebutornye et al, 2019 ). The exogenous microorganisms were used to enhance the water purification effect when combined with purification materials that can provide a microorganism-loaded environment ( Ren et al, 2021 ; Yin et al, 2022 ). The nitrifying and phosphorus-accumulating bacteria were enriched when added microorganisms in the activated sludge ( Kuśnierz et al, 2022 ).…”

The study tested the water purification mechanism of the combination of microorganisms and purification materials via characteristic, enzymatic, and metagenomics methods. At 48 h, the removal rates of total nitrogen, total phosphorous, and Mn chemical oxygen demand in the combination group were 46.91, 50.93, and 65.08%, respectively. The alkaline phosphatase (AKP) activity increased during all times tested in the volcanic rock, Al@TCAP, and exogenous microorganism groups, while the organophosphorus hydrolase (OPH), dehydrogenase (DHO), and microbial nitrite reductase (NAR) activities increased at 36-48, 6-24, and 36-48 h, respectively. However, the tested activities only increased in the combination groups at 48 h. Al@TCAP exhibits a weak microbial loading capacity, and the Al@TCAP removal is primarily attributed to adsorption. The volcanic rock has a sufficient ability to load microorganisms, and the organisms primarily perform the removal for improved water quality. The predominant genera Pirellulaceae and Polynucleobacter served as the sensitive biomarkers for the treatment at 24, 36-48 h. Al@TCAP increased the expression of Planctomycetes and Actinobacteria, while volcanic rock increased and decreased the expression of Planctomycetes and Proteobacteria. The growth of Planctomycetes and the denitrification reaction were promoted by Al@TCAP and the exogenous microorganisms. The purification material addition group decreased the expression of Hyaloraphidium, Chytridiomycetes (especially Hyaloraphidium), and Monoblepharidomycetes and increased at 36-48 h, respectively. Ascomycota, Basidiomycota, and Kickxellomycota increased in group E, which enhanced the nitrogen cycle through microbial enzyme activities, and the growth of the genus Aspergillus enhanced the phosphorous purification effect.

“…Bacillus species are often applied as biocontrol strains owing to their ability to produce a variety of biocontrol agents [ [1] , [2] , [3] , [4] ]. Cyclic lipopeptides of Bacillus , such as surfactin, iturin, and plipastatin (fengycin), have well-known potential in biotechnology and biopharmaceutical applications due to their biosurfactant properties, antibacterial, antifungal, and antiviral activities [ [5] , [6] , [7] ].…”

“…The large amounts of feed and metabolites in aquaculture wastewater promote the eutrophication of seawater and coastal wetlands, which may destroy the seagrass bed ecosystem. The main pollutants found in aquaculture are ammonia nitrogen, nitrate, nitrite, and phosphate (Ren et al ., 2021; Wei et al ., 2021a). Environmental pollution in aquaculture has been reported to affect seagrass microbial community, and the microbial community of seagrass sediment is known to be more sensitive to the duration of exposure and concentration of polycyclic aromatic hydrocarbons (PAHs) (Ling et al ., 2015).…”

The global seagrass bed ecosystem acts as a natural ecological barrier in the littoral coastal zone. In recent years, this ecosystem has suffered from serious eutrophication and destruction caused by the continuous expansion of aquaculture. However, our understanding of the influence of aquaculture on the bacterial community remains limited. In this study, we used 16S amplicon sequencing to evaluate the impact of aquaculture feed extract solution on the composition and function of bacterial epiphytes and endophyte communities of the core seagrass from the seagrass bed ecosystem in Hainan, Thalassia hemprichii. The feed extract solution was the main factor that significantly affected the bacterial epiphyte and endophyte community structure of seagrass leaves but had no marked effect on alpha diversity was observed. Additionally, the bacterial epiphyte and endophyte community of the T. hemprichii leaves alleviated the effects of organic matter, sulfide, and nutrients caused by aquaculture wastewater. The feed extract solution promoted the proliferation of Bacteroidales, Vibrio, Desulfobulbaceae, Desulfobacteraceae, Pseudoalteromonas, Paludibacter, Marinomonas, and Pseudomonas in the leaves and root of T. hemprichii, which can effectively improve the digestibility of eutrophication. In fact, Desulfobacteraceae and Desulfobulbaceae can reduce sulfate to sulfide and oxidize sulfide to sulfur within seagrass, indicating that the increase in Desulfobulbaceae and Desulfobacteraceae facilitated the accumulation of sulfide with the treatment of feed extract solution, which may be the reason for the degradation of seagrass caused by aquaculture wastewater containing high concentrations of organic pollutants. These results suggest that although seagrass beds can withstand low concentrations of aquaculture pollutants, sulfide emissions should be minimized.
