- Abstract
Effects of moderate-intensity static magnetic field (SMF) on biodecolorization of azo dyes by a marine microbial community (MMC) and halotolerance of the consortium were investigated. Performance of decolorization, chemical oxygen demand (COD) removal, detoxification, and biomass multiplication exposed to SMF of different intensities were monitored and compared. In addition, effects of SMF on microbial community structure were analyzed using a high-throughput sequencing technique. Results showed that compared with those with the MMC without SMF, efficiencies of decolorization, COD removal, and detoxification were higher when exposed to 45.3 mT SMF; however, they were lower when exposed to 95.0 and 249.5 mT SMF. By contrast, biomass multiplication was enhanced by all the three tested SMFs. On the contrary, 45.3 mT SMF also enhanced halotolerance of the MMC. Results of MiSeq sequencing demonstrated that 45.3 mT SMF influenced biodiversity and structure of the MMC, and the relative abundance of some putative genera involved in azo dye decolorization increased, including bacteria such as Shewanella and Vibrio, fungi such as Issatchenkia, and genera affiliated to unclassified Pseudeurotiaceae. This study might provide a potentially useful pathway for improving effectiveness of biological treatment processes and their tolerance to extreme conditions in practical applications.
