DDT (1,1,1-trichloro-2,2 bis(4-chlorophenyl) ethane) is a synthetic insecticide that has several negative effects on the environment and humans. Therefore, determining an effective method to reduce may give beneficial impact. Brown-rot fungus, Gloeophyllum trabeum, well known have ability degrade DDT, even though it might require long-term remediation. In this study, effect of addition bacteria biodegradation by G. trabeum had been investigated. Bacillus subtilis, Pseudomonas aeruginosa, Ralstonia pickettii were screened for which volume at 1, 3, 5, 10 mL time range days 0, 5. The B. P. R. into culture increased approximately 62.02; 74.66; 75.72%, respectively, in was only able 54.52% 7 incubation. enhanced degradation process, bacterium day 1 possessed highest value 92.41% within DDD detected be product metabolite through dechlorination reaction. This study indicated mixed cultures can used DDT.

Burning question: Rethinking organohalide degradation strategy for bioremediation applications

Microbial Biotechnology, Год журнала: 2024, Номер 17(8)

Abstract Organohalides are widespread pollutants that pose significant environmental hazards due to their high degree of halogenation and elevated redox potentials, making them resistant natural attenuation. Traditional bioremediation approaches, primarily relying on bioaugmentation biostimulation, often fall short achieving complete detoxification. Furthermore, the emergence complex halogenated pollutants, such as per‐ polyfluoroalkyl substances (PFASs), further complicates remediation efforts. Therefore, there is a pressing need reconsider novel approaches for more efficient these recalcitrant pollutants. This review proposes redox‐potential‐mediated hybrid bioprocesses, tailored physicochemical properties contexts, achieve detoxification organohalides. The possible scenarios proposed discussed. In anaerobic environments, sediment groundwater, microbial reductive dehalogenation coupled with fermentation methanogenesis can convert organohalides into carbon dioxide methane. environments anaerobic‐aerobic alternation, paddy soil wetlands, synergistic process involving reduction oxidation facilitate mineralization highly organic compounds. Future research should focus in‐depth exploration consortia, application ecological principles‐guided strategies, development bioinspired‐designed techniques. paper contributes academic discourse by proposing innovative strategies complexities organohalide pollution.

Enhanced in situ bioremediation of chlorinated ethenes: from in situ microcosms to full-scale application

Bioremediation Journal, Год журнала: 2024, Номер unknown, С. 1 - 17

Concentrations greater than 20 mg/L of chlorinated volatile organic compounds (cVOCs) including tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (cDCE) have been present in site groundwater for more four decades. To promote a faster clean-up time, an situ bioremediation approach was evaluated using In-Situ Microcosms® (ISMs) followed by full-scale approach. The ISM study slow-release versus quick-release carbon substrates with without bioaugmentation the ethene degrading culture, SDC-9™. After three-month incubation period, ISMs were retrieved. amended source or displayed 93% reduction TCE, which corresponded to increase cDCE all ISMs. Dehalococcoides population gene abundances associated biodegradation (tceA, bvcA, vcrA) increased three orders magnitude bioaugmented over natural attenuation only Additionally, SDC-9™ AquaBupH®, enhanced emulsified oil substrate (EOS®) buffer, unit showed highest level vinyl chloride similar EHC®, controlled-release, organo-iron substrate, ISM.
