Abstract
- This study investigates the effectiveness of modified micrometer graphite (MMG) in enhancing the biodegradation of perchlorate in sludge. Different MMG types, specifically GO205, GO003, ATGO205, and ATGO003, were evaluated for their impact on perchlorate degradation rates. The results showed a significant acceleration in perchlorate reduction, particularly with the MMG variant GO205, which achieved complete degradation within 48 hours, marking a six-fold increase compared to controls. This rapid degradation also correlated with enhanced microbial activity, as indicated by increased cytochrome C concentrations and electron transport system activity, suggesting a boost in overall microbial metabolic functions. Additionally, shifts in the microbial community composition were observed, with a notable increase in perchlorate-reducing bacteria populations. The study highlights MMG's potential to improve perchlorate remediation processes efficiently and offers promising insights into its application in treating perchlorate-contaminated environments. [Display omitted] • Addressed persistent perchlorate contamination from industrial sources. • Used MMG to enhance microbial perchlorate biodegradation in batch experiments. • Conducted UASB reactor trials with MMG with 40 days. • MMG can change microbial community structure and pcrA gene transcription. • MMG enhances biodegradation efficiency, aiding sustainable wastewater treatment.
