چکیده انگلیسی
Traditional methods to combat disease with antimicrobial agents in aquaculture have caused serious concern and alternative approaches using probiotics have been sought. A photosynthetic purple sulfur bacteria Marichromatium purpuratum RuA2 that thrives at salt concentrations of 0.5% to 5.0% and has a more temperate tolerance for oxygen was isolated from a marine fish pond located on the southwestern shore of Qigu, Taiwan. The effects of M. purpuratum RuA2 on the water quality parameters, the occurrence of the sulfonamide resistance gene sul1 and the microbial community were investigated in situ. Supplementation with strain RuA2 resulted in an increased removal rate of total organic carbon and nitrate ions, as well as a lower occurrence of sul1, in the bacterial community. The abundance and diversity of the bacterial community in the control and M. purpuratum RuA2-supplemented water samples were investigated. Proteobacteria, Bacteroidetes, Cyanobacteria, Actinobacteria and Planctomycetes were identified to be the top five predominant phyla in the control and M. purpuratum RuA2-supplemented water samples. However, supplementation with M. purpuratum RuA2 increased the diversity of the bacterial community composition. Fourteen unique genera were detected solely in strain RuA2-supplemented water samples and the relative abundance of seven shared genera was associated with supplementation with strain RuA2. In conclusion, M. purpuratum RuA2 showed a desirable capacity for improving water quality, reducing the occurrence of the resistance gene sul1 and advantageous effects on the microbial community structure. Tolerant to salinity and oxygen, M. purpuratum RuA2 exhibits an attractive potential for resolving the challenges facing aquaculture today.
